About Senior Design Project (SDP)
Symposuim allow students to test their engineering knowledge in a related field setting prior
to graduation. On each project, three to four students collaborate to design, build, and test a
realistic engineering system under faculty supervision. Each project is completed for a real
task, thereby giving students an opportunity to experience engineering challenges paralleling
those found in the real life learning. While working on the projects, students must consider
safety, economic, environmental, and ethical concerns.
By working on capstone projects the students learn to deal with open-ended questions, and
get a chance to pull together as a group the many things they've learned in classes throughout
their undergraduate degree. Completed senior design projects in a range of disciplines are
showcased each spring at the Engineering Design Expo in the Integrated Teaching and
Learning Laboratory.

ABSTRACT
The universal motor is a common motor used in various applications and they
have distinctive characteristics including: having a high starting torque and
rotation at high speeds. The objective of our work in the Senior Design Project
is to design and implement a semiconductor-based converter for controlling the
speed and the direction of the universal motor. This is achieved through using a
power electronic converter, namely; a line bridge incorporating triacs across the
motor field winding. This is useful in controlling both the direction and the speed
at the same time. The speed is governed by controlling the firing angle to reduce
the voltage applied to the motor, and by switching the arms the exciting field
current is switched, which causes reversing of rotation.
Key Words: universal motor, Triac Bridge, Speed control, Direction reversing.

ABSTRACT
Induction motors are being widely used for various applications such as
conveyor systems, blowers, fans, etc. The efficiency of these systems depends
on the performance of induction motor, which in turn depends on the starting
and running performance of induction motor. The three phase induction motor
during the initial starting condition draws up much higher current than its
capacity. This results in a mechanical jerk and thermal stress on the windings
of the motor. Sometimes, the windings may get burnt. To solve this problem,
many solutions have been provided to take over on this high current such as
auto-transformer, star-delta and frequency converter. This project is based on
resolve this problem by giving a smooth start to the induction motor based on
using the SCR (triacs) which is triggered at larger delayed firing angle during
starting, and then gradually reducing the delay till it reaches zero voltage
triggering. This results in low voltage during start and then gradually increase
to full voltage. Thus the motor starts slowly and then slowly picks up to full
speed. The control of starting voltage is done by using micro-controller
(Arduino). Key Words: Qassim University, College of Engineering, Induction

ABSTRACT
Over the last few decades, enormous changes have been witnessed in power system
structure and therefore, their operational and control problems become very complex and
difficult. Operating a power system in interconnected fashion has aggravated the complexity
further. To provide good quality of electricity to consumers, an effective and reliable control
schemes are required to regulate the system frequency and voltage levels to their nominal
values following the load disturbance in the system. The present SDP aims to design PID
structured controllers to regulate the frequency of a two-area interconnected power system
consisting of reheat thermal turbines in the wake of step load disturbance in the system. As
generation rate constraint(GRC) is generally imposed in real time power system operation on
generators, the effect of GRC on system dynamic performance is incorporated in the study.
From the investigations of the system dynamic plots obtained for step load disturbance in one
of the areas, it is revealed that the designed regulators/controllers are very effective to mitigate
the deviations caused due to disturbance. Moreover, it is shown that incorporation of GRC
has resulted in the deterioration in system dynamic performance..

ABSTRACT
In last few decades, electric power demand is increasing at a very fast pace and the power
industry has witnessed many structural and technological changes. The stability of power
system has become more difficult these days as consumption of electrical power fluctuates
randomly. Due to limited resources of power generation, the transmission lines getting
heavily loaded and facing the various important issues like; stability, voltage sag, and
reactive power. The FACTS technology is essentially proved in tackling these issues and
able to alleviate them efficiently. Flexible alternating – current transmission systems
(FACTs) devices usually install power electronic devices at the appropriate places of the
existing AC systems to enhance controllability and increase power transfer capability. In this
project, the various reactive power compensation techniques based on FACTS devices like
thyristor controlled phase shifter (TCPS), static Var compensators (SVC) and Static
Synchronous Series Compensator (SSSC) are considered for design and implementing the
voltage control schemes in the power system network using Power System Analysis Toolbox
(PSAT) via the link with MATLAB.

ABSTRACT
Growing concern for environmental issues poses significant chance to utilization of
distributed renewable energy resource. The intermittent nature of renewable energy put power
system at risk. Microgrid is introduced as a strategy to integrate renewable energy resource
from various locations with power system. In addition, Battery energy storage (BES) plays an
important role in microgrid operation and control, as it can potentially improve local reliability
and resilience, reduce operation cost, and mitigate challenges caused by high penetration
renewable generation. The main drawback that limits the installation of BES is their high
investment cost. However, to ensure an acceptable economic and technical performance, BES
must be optimally sized in terms of its power rating and energy rating size. In this project, the
concept of microgrid is studied and the applications of BES in microgrid operation are
discussed. Moreover, a BES design model that enables microgrid planners to determine the
optimal size of the installed BES is developed.

ABSTRACT
Over the past several decades, digital information science has emerged to seek answers to the
question: can any technique ensure tamper-resistance and protect the copyright of digital
contents by storing, transmitting and processing information encoded in systems where digital
content can easily be disseminated through communication channels? Today it is understood
that the answer is yes. Digital watermarking is a technology of embedding watermark with
intellectual property rights into images, videos, audios, and other multimedia data by a certain
algorithm. The basic characteristics of digital watermark are imperceptibility, capacity,
robustness, Low Complexity and security of the hiding place. Moreover, the Classification of
digital watermarking applications are Copyright Protection, Fingerprinting, Copy Control,
Content integrity, Broadcast Monitoring, Owner Identification and Medical Applications. The
digital watermarking can be embedded by a several domains. Every domain used in the
embedding has weaknesses and features. The digital watermarking can be implemented using
several platforms. However, in this report it is implemented using MATLAB.

ABSTRACT
Due to hot weather or parking cars without shades (especially in summers) makes inside
of the car too hot which in turn makes it unbearable and difficult for not only passengers to
sit but also for driver and also for electronics of the car. Therefore, there is a need to develop
a system, which can ventilate the hot air in the car. Consequently, this project will develop a
low cost system to vent the air. The goal of the project is to reduce automobile's temperature
by throwing the hot air outside before the driver or passenger gets into the vehicle. The effect
of the product will be studied and will be analyze to study the engine is not overburdened,
conserving energy, protecting the environment and improving comfort. The main functions
of product will be to provide coolness, protect the car electric appliance, and health.

ABSTRACT
It is important for every school and parents to have a trustworthy and secure transportation
service to ensure the safety of the students. This has become a major concern for parents now-
a-days due to accident ratio along with incidents such as many children find themselves
locked in a school bus in the bus parking lot after falling asleep on their way to school, miss
the bus, or leave at the wrong station. It is also required for school administration to effectively
manage their bus fleet, potentially reduce mishaps, and ensuring the safety and security of the
students. This is where vehicle monitoring, organizing and alerting system takes effect. The
proposed system in the project provides real time information about various parameters of
vehicle (i.e. location, the route, the list of passengers, the adherence of drivers to schedule and
much more) by using appropriate sensor and alarm system. In our system we make use of
RFID (MFRC522), to identify each student as they board or alight the vehicle by reading the
id from their RFID tags. GPS (NEO-6M) technologies, is used to find the current geographic
coordinates of the vehicle's location. In order to connect them to a remote server over Wi-Fi,
Arduino (ESP-01) microcontroller has been used, to upload the information from the
peripherals to a database in the web server. The system consists of three main units, bus unit,
parent unit, and school unit. The bus unit is used to detect when a child enters/exits from the
bus using RFID Card. In addition, it checks the reading of the sensors inside the bus. That
information is sent to the parent unit and school unit. Parents unit is an Android app that helps
parents to track their kids effectively by providing them with information about the kid and
the bus. The parents can also use the app to estimate the arriving time of the bus too. The
school administration can also access the application to ensure student safety and contact a
driver or a parent. The application also allows the administration to be informed of
emergencies. The overall system is integrated together through a common database based on
internet of things (IoT) technology.

ABSTRACT
Sustainable design of wastewater treatment plant plays an important role to the management
of wastewater. The main objective of the project is to design the wastewater treatment plant
for the Qassim University based on predicted population growth in 2030. The comprehensive
design was developed for the units of Grit Removal, Primary sedimentation tank, Rotating
Biological Contactor (RBC), Secondary sedimentation tank, Rapid sand filter and
Disinfection tank. A details design of plant hydraulics and piping with economic analysis
was performed. The plant design was considered as many sustainable and cost effective
concepts as possible, in order to keep construction and maintenance costs low. The calculated
volume of different treatment units for the year of 2030 were compared with the current
wastewater treatment plant and eventually noted down the important observations that have
resulted from the comparison. Our design calculation showed that the most of the existing
plant treatment units have to be extended around 1.5 times in 2030 to meet the wastewater
management in Qassim University. The results of this project may serve as a useful tool for
the management of wastewater for the Qassim University.

ABSTRACT
Water saving for different uses in Saudi Arabia is a critical issue. Wadi Al-Romah is the most
important Wadi in Qassim area, Saudi Arabia. It runs with its full capacity once every 33
years. During its running with full capacity, the amounts of water loss are highly significant.
In this project, the amount of water losses was calculated and found to be 11,938,761.6
m3/year. Accordingly, various parameter of the rehabilitation of Wadi were designed, using
state of art techniques. As the result of design two proposals of cross-section for Wadi Al-
Romah are provided considering the optimal saving of water. The first one, will save around
9.1 million m3 of water per year. The other one will save an amount of 10.98 million m3/year.
For augmentation of Wadi Al-Romah flow, recharge of groundwater via infiltration in the
downstream part of Wadi was estimated and found to be 208,77 m3/day. Three downstream
ponds, located at east south of Buraydah, were investigated. The area, depth, and volume of
these ponds were estimated. Volumes of these ponds are found to be not sufficient to
accommodate the volume of water flowing in Wadi Al-Romah as the result of rainfall. The
extra water beyond the capacity of these ponds usually causes floods in Buraydah the Capital
of Qassim. Hence the volume of these ponds must be increased to save Buraydah from floods.
Recharge wells also were proposed to help in this regards.

ABSTRACT
Cavitation is recognized to be one of the interesting phenomena that occur in the pumping
system. The purpose of this work is to design a test-rig for vibration diagnosis of pump
cavitation. To achieve this purpose, a centrifugal pump was selected with the appropriate
specifications that will enable the diagnosis of cavitation using vibration signals. The
selected pump has been modified by inserting a new driving unit with a speed controller. A
reversible engineering process has been conducted to design the shaft in order to check the
pump shaft capability to handle the new modification on the pumping system. The
measurements are conducted on a test setup equipped with two accelerometers and one
sensitive microphone to correlate their output signals with the emerged cavitation.

ABSTRACT
Erosion – corrosion (E-C) of metallic materials designates the material degradation where
mechanical wear by solid particles, liquid or the combination of both processes interacts with
corrosion caused by dissolution or surface oxidation. E-C phenomenon has caused many problems
resulting in a material loss and equipment failure. Therefore, the phenomenon received an
increasing attention from researchers all over the world. The main difficulty when trying to get

ABSTRACT
Exposure to high concentrations of particulate matter (PM) is known to cause serious respiratory
health problems, including asthma. PM is emitted during residential wood combustion and
incomplete combustion contributes to increase the concentrations of airborne particulates indoors.
In Saudi Arabia, a lot of homes have a room for burning wood called almushab. It is generally
occupied during the winter season and it might be considered the main emission sources of
particulate matter in Saudi homes. However, to the best of our knowledge, no efforts have been
made to assess the air quality in almushab rooms. Thus, in this senior project design, a typical
almushab room equipped with chimney chosen from a typical residential home in Buraydah is
used to conduct the investigation The results showed high mass concentration of PM,
particularly the mass in the smaller particles (<0.65 μm). Our findings demonstrate that air quality
in almushab room is poor and the concentration of airborne particles is elevated compared to the
standards set by the US Environmental Protection Agency (EPA). In addition, the data collected
from the pilot experiment were utilized to select the appropriate filters for the project. In the next
phase of our project, an air cleaner system will be designed and evaluated.

ABSTRACT
The objective of this Senior Design Project (SDP) is to design and implement a novel idea
in the area of air conditioning (AC). The aim of designing the new AC is to make it compact
and portable. There will be no refrigeration cycle embedded within our design, rather the use
of phase change materials (PCM) will be implemented. Water will be used as the phase-
change material since it is the most affordable type of PCMs. The AC will be used for a
period of 3 to 8 hours depending on several factors such as the mass of the PCM used, the
inlet air temperature, and the mass flow rate of inlet air. The AC is composed of the body
which is insulated, a fan, and the PCM. The air is moved by the fan, then the air exchange
heat with the ice and therefore the temperature drops and the ice melts after a certain period.
The AC is designed to be portable and to work within a small personal area.

ABSTRACT
The idea of the project was stemmed from “the need to catch an object when it enters the
reachable zone of the gripper and hold it for a while”. This idea was behind the control
strategy, which may be summarized as that the reachable space of the gripper is to be scanned
by a position sensor to detect if the object exists or not. Upon the existence of the object; the
controller signals the motor to move such that the gripper ends (jaws) clip the object, hold it
for a specific delay time then leave it. This delay time simulates as if the gripper was attached
to an arm and the arm is moving it to another destination. The control system is based on the
use of simple closed-loop control topology by programming an ARDUINO controller to
control the motion of the servo motor.
The conceptual design technique is utilized during the progress of this project. This includes
the use of Kepner-Tregoe Decision Analysis (KTDA) technique to select all components. The
project shows the dynamic analysis of the four joint mechanism. The project also contains the
steps of manufacturing a pre-gripper model by using the 3d-printer facilities. The
experimental tests conducted to test the system gave quit satisfactory results.

ABSTRACT
The electrical power system structure is operationally connected to many control areas
spreading over a large electrical area. This has made the controlling aspect of power system
a huge concern for all power engineers. Today’s life is dominantly reliant on the electrical
energy and the increasing power demand is to be balanced by the generation of power. The
automatic generation control (AGC) strategy is imperative in balancing the power in the
network and take care of frequency maintenance and tie-line flows. The conventional power
structure transforming into the market oriented model and splitting the entire single central
entity to different operational business modules. This deregulated and restructured power
system has separate module entities like generation transmission and distribution companies
and also the retail wheeling of power. However, this transition has posed many new technical
issues and challenges to the operation of deregulated power systems. Therefore, the existing
fundamental principles of operational and control philosophies are to be modified to handle
new power system environment.
In this proposed work, the conventional PID controllers and optimal controllers are to be
designed for AGC of interconnected power systems operating in deregulated environment.
The state space model of restructured power system shall be developed for AGC scheme
design and its implementation. The control scheme is to be designed based on the
conventional and optimal control theory concepts. The dynamic responses are to be
compared for both controller design techniques and stability analysis shall be done. The
MATLAB software and associated tools will be utilized to perform computation work and
the results so obtained may be investigated.

ABSTRACT
Municipalities in Saudi Arabia are managing their municipal solid waste management
(MSWM) systems without a structured performance assessment mechanism. For reliable
operations, all the key components of a MSWM system need to perform efficiently. First
framework is developed for selecting performance indicators for seven key components,
including public service and participation, personnel, physical assets, operational,
environmental, sustainability, and financial. Interview surveys were conducted with decision-
makers from two municipalities and academia in the Qassim Region to evaluate the indicators
against their ‘relevance’, ‘measurability’ and ‘understandability’. Fuzzy Analytic Hierarchy
Process (F-AHP) and PROMETHEE II were used to select and rank 58 PIs. Subsequently, a
hierarchical modeling framework, based on deductive reasoning, is developed for
performance assessment of the key components. Fuzzy rule based modeling is performed
using Simulink-MATLAB for performance inferencing at different levels of the hierarchy.
The model efficiently handles the inherent uncertainties due to limited data and imprecise
knowledge base. Results can exclusively assist the managers working at different levels of
organizational hierarchy for effective decision-making. The model has been implemented on
two medium-sized municipalities operating in Qassim. The results demonstrate the model’s
pragmatism for continuous performance improvement of MSWM systems in the country and
possibly elsewhere.

ABSTRACT
Water directorates in Kingdom of Saudi Arabia (KSA) are facing challenges related to both
the quantity and quality of water due to low annual rainfall, depleting water resources, and
presence of naturally occurring substances in groundwater. As a result, they are striving to
meet municipal water demand with adequate water quality through intermittent water supply.
Although, raw groundwater is being treated with expansive treatment processes, intermittent
water supply and in-house storage have led to various water quality problems at the consumer
end, such as possibility of bacterial contamination. In this research, a comprehensive risk-
based water safety management model will be developed to identify, analyse, and reduce the
water quality problems from source to the consumer tap. Root Cause Analysis will be
conducted to identify potential hazards in water source, treatment plant operations, treated
water storage, distribution networks, and the in-house plumbing system. Subsequently,
Fuzzy-Failure Mode and Effect Analysis (Fuzzy-FMEA) will be applied to assess and
prioritize different hazards. The model will be able to deal with different types of uncertainties
associated to the vagueness in expert opinion, data limitations, and inaccuracies in
measurements of water quality parameters. Based on the model results, the Water directorates
will be able to plan their available investments to minimize the hazards with highest risk
priorities. The model will be implemented on the water supply system in Unayzah to evaluate
its practicality for other water directorates in Qassim, other regions in KSA, and elsewhere in
the world.

ABSTRACT
In arid and semi-arid countries, it is required to identify alternative potential sources of water
and develop sustainable technologies for their recycling. A large amount of less contaminated
ablution greywater (AGW) is being produced at the mosques in all Muslim countries
including Kingdom of Saudi Arabia (KSA). Therefore, AGW certainly possesses significant
potential for recycling. In this study, a simple and cost-effective sustainable ablution
greywater recycle system (SAGWRS) is proposed to collect, treat and recycle the AGW
within the periphery of a mosque for toilet flushing. A conceptual model for SAGWRS was
developed and evaluated through techno-economic analysis. The SAGWRS consists of a
AGW collection and storage system, low cost ceramic filtration unit, activated carbon
adsorption column, chlorine dispenser, and overhead tank to collect and distribute treated
AGW. The SAGWRS meets the water quality standards for toilet flushing as well as for
irrigation. A simple operation and maintenances procedure made the system sustainable and
cost effective. The estimated cost (0.7-1.0 US$/m3) of the SAGWRS was found to be
considerably less than the municipality water cost (1.71 US$/m3) in KSA. SAGWRS
proposed in this study would be a prospective recycling practice of AGW in KSA for
sustainable development. Based on the techno-economic analysis, the proposed system
provides a sustainable approach of water conservation by on-site recycling of AGW in
Muslims countries around the world.

ABSTRACT
Additive manufacturing technology (AMT) is playing a more impact in the current
manufacturing industries. In olden days, this technology was pronounced as rapid prototyping
technology (RPT) as it was used to fabricate the reduced scale models of some large size
projects (design of aircrafts, locomotives, space crafts, human anatomy etc…). However, this
AMT is being used to fabricated all kind of highly complicated parts now-a-days especially
this technology is a boon for the medical applications (implant parts/bones/tissues). Several
thermoplastics, some metallic materials, and some ceramic powders can be printed as a
product in a few processing steps, namely, design of parts using CAD software, conversion
of file, and fabrication of part using any 3D printing technology (fusion deposition modeling,
selective laser sintering, Stereo-lithography, and 3D plotting). Among the various AMTs,
fusion deposition modeling (FDM) is a simple process which is being used in the aircraft
parts, bioparts / artificial bones, tissues, decorative models, teaching aids etc…. FDM can
easily print all kind of thermoplastics in which poly lactic acid (PLA) is a common polymeric
materials as it is easily available, less expensive, lower melting point, non-toxic, and
biocompatibility. This review poster presentation was aimed to present the various steps
involved in the 3d printing technology, general principle involved in FDM process, review of
literature related to PLA parts obtained from FDM, and investigate the various process

ABSTRACT
High Performance Concrete (HPC) is one of the most effective techniques in concrete
technology business. It has better quality than conventional concrete. However, the most
concerning problem of HPC is the high brittleness. Therefore, steel fibers are added to HPC
to investigate the reduction of the brittleness of the concrete upon becoming High
Performance Steel Fibers Concrete (HPSFC). The main purpose of this research is to
investigate the brittleness of the high performance concrete by including steel fibers in the
mix design. In addition, some of the tests are performed to evaluate the quality of the concrete.
Results show that increasing the percentage of fiber reduces the brittleness of the concrete,
as well as improving a number of other mechanical properties. Regression equations are
generated for design guidance.
Key Words: High Performance Concrete, steel fibers, mix design, brittleness.

ABSTRACT
Implants are very important in surgery applications and it is very difficult to replace the
injured/damaged human parts by another one (human donors). Day-by-day, the demand for
implants parts are increasing drastically due to accident/natural calamity. To save the human
life and improve their lives, it is necessary to manufacture the artificial implants which can
be fabricated through polymers, metals/alloys, and ceramics. These artificial implant parts
would help the life of the patients and enable them to continue their life probably. For such
applications, the materials used to make these devices must be chosen carefully. The current
work aims to provide an integrated idea about the implants materials used in medical
applications, examine the mechanical properties and various processing techniques.
Conventional techniques, namely, machining, metal forming, investment casting, CNC
machining etc.. Can be used to fabricate the implant parts. However, it will be very difficult
to maintain the dimensional accuracy in the complicated implants. Hence, the additive
manufacturing techniques can be used to resolve these issues.

ABSTRACT
The utilization of wind energy is very important and vital as all the experts have expected the
rapid exhaust of the conventional energy resources. One of the new trends is to generate
electrical power by using the clean and renewable wind power extracted by wind turbines.
Wind-turbine prime-mover has the problem of being of variable and unexpected speed these
mechanical power can be converted into electrical power by using electrical induction
generators. This raised the need to use the induction generators instead of the conventional
synchronous generators to solve the problem of variable speed turbines.
This research aims to maximize the power obtained from the wind energy, and to improve the
performance characteristics of the wind-driven induction generators. This will be done
through suggesting a simple method for controlling the cheap cage induction generator such
that wind turbine will trace the maximum extracted power locus at different wind speeds.

ENHANCING THE PERFORMANCE OF SELF-EXCITED
WIND-DRIVEN CAGE INDUCTION GENERATOR
THROUGH ALTERING THE POLES

Department of Electrical Engineering
College of Engineering, Qassim University
ABSTRACT
Abstract: The renewable wind energy encountering a globally rapid growth to become an
important electricity source, which replaces the polluting and exhaustible fossil fuel. The
induction generators are commonly used to transform the mechanical energy of the wind to
electrical energy. Various techniques have been employed to extract the topmost energy from
the wind streams. The present research aims at enhancing the performance of the self-excited
wind-driven cheap cage induction generators at the different wind speeds employing control
technique by altering the number of poles of the cage generator and adjusting the shunt
capacitor. The control aims to maximize the input power captured from the wind, and to
improve the generator electrical performance when the generator feeds static loads, and when
supplies dynamic induction motor load. A complete mathematical model and computer
simulation has been performed, and control protocols for the capacitor and poles have been
reached which governs the generator speed such that the wind turbine blades revolves at speed
which is optimally proportional to the wind stream speed. Consequently, the highest
mechanical power is being taken from the wind. At the same time, the built-up voltage is
adjusted around the load rated voltage for static loads. In case of dynamic induction motor
loads, the poles are fixed at the minimum number, and good performance is possible through
controlling the capacitor size. Study of the system through a developed simulating computer
program (MATLAP) or use of software program package if difficulties occurred during
programming the mathematical model of the system. Published an article in Indian Journal of

Supervised by: Associate Prof. Dr. Ahmed Abdelwahab
Date: 9th April. 2019 (392)
Abstract:Over the past several decades, digital information science has emerged to seek answers to the question: can any technique ensure tamper-
resistance and protect the copyright of digital contents by storing, transmitting and processing information encoded in systems where
digital content can easily be disseminated through communication channels? Today it is understood that the answer is yes. Digital
watermarking is a technology of embedding watermark with intellectual property rights into images, videos, audios, and other multimedia
data by a certain algorithm. The basic characteristics of digital watermark are imperceptibility, capacity, robustness, Low Complexity and
security of the hiding place. Moreover, the Classification of digital watermarking applications are Copyright Protection, Fingerprinting,
Copy Control, Content integrity, Broadcast Monitoring, Owner Identification and Medical Applications. The digital watermarking can be
embedded by a several domains. Every domain used in the embedding has weaknesses and features. The digital watermarking can be
implemented using several platforms. However, in this report it is implemented using MATLAB.
Objectives:
The main objective of digital marking is to make a mark that refer to ownership.
Make hiding information that have negligible effect on quality.
To make The digital watermarking standing ageist the attacks .
Description:In this project, the parameters can changes to achieve the ownership goals like block size, Wight of the embedding, threshold and
imperceptibility. There are tradeoff between these parameters. Therefore, to measure specific parameter, the other parameters must be constant
at the average. Then choose the best selection . After that use this selections of all parameters to get the optimum results .the figures as shown
below explains the effect of changes on every parameter.

Conclusion and recommendations:The suitable technique for the application copyright protection is digital watermarking technique. Watermarking has characteristics and criteria
which are robustness, Imperceptibility and others. Therefore, ownership have to concede all these criteria because they are related to each other.
The classification of digital watermarking applications like copyright protection, owner identification and others are discussed. MATLAB reads
grey images as a matrix with NxM size and every pixel in this matrix has 8-bits binary word. Moreover, the MATLAB can divide the image into
edge and shade blocks using block variance. Therefore, the total number of edge blocks is the capacity of the image. After that the secret massage
will embed into these blocks and use random permutation for selected edge blocks as a secret key. The embedding can be in several domains.
There is tradeoff between the characteristics of watermarking. Therefore, the characteristic’s changes must be thoughtful. The project needs

Date: 9th April, 2019 (392)Abstract
Induction motors are being widely used for various applications such as conveyor systems, blowers, fans, etc. The efficiency of these systems depends
on the performance of induction motor, which in turn depends on the starting and running performance of induction motor. The three phase induction
motor during the initial starting condition draws up much higher current than its capacity. This results in a mechanical jerk and thermal stress on the
windings of the motor. Sometimes, the windings may get burnt.
To solve this problem, many solutions have been provided to take over on this high current such as auto-transformer, star-delta and frequency converter.
This project is based on resolving this problem by giving a smooth start to the induction motor using the SCR (triacs) which is triggered at larger
delayed firing angle during starting, and then gradually reducing the delay till it reaches zero voltage triggering. This results in low voltage during start
and then gradually increase to full voltage. Thus the motor starts slowly and then slowly picks up to full speed. The control of starting voltage is done
by using micro-controller (Arduino).
Key Words: Induction motor, motor current control, SCR triggering, Starting current, phase angle control
Objectives and Motivations
Design a 3‐phase AC voltage controller power circuit.

Date: 9th April. 2019 (392)Abstract :Due to hot weather or parking cars without shades (especially in summers) makes inside of the car too hot which in turn makes it unbearable
and difficult for not only passengers to sit but also for driver and also for electronics of the car. Therefore, there is a need to develop a system,
which can ventilate the hot air in the car. Consequently, this project will develop a low cost system to vent the air. This project will adopt
airflow management technology to improve the local temperature distributions in an automobile to counteract the greenhouse effect. Thus,
goal of the project is to reduce automobile's temperature by throwing the hot air outside before the driver or passenger gets into the vehicle .
The five main functions of product will be to provide coolness, deodorization, demister, protect the car electric appliance, and health.
Objectives and Motivation:
• Design and implement simple
Vehicle Air Ventilation System.
• Study and design of input sources.
• Save the life of the children.
• Decrease the fuel consumption.
• Reduces heat damage to health.
Description:
For a parked car in an open area, solar radiation will heat the equipment inside the car. As a result, the driver
needs to run the air conditioning before starting to drive. This will increase the fuel consumption of the
vehicle because of the use of the AC at its maximum consumption. Moreover, this will effect the health of the
body because of breathing the toxic gas and also it will damage the electronics. So, to solve these problems
we designed a system that will help to reduce the temperature inside the car.
Conclusion and Recommendations:
• The ventilator can reduce temperature up to 8 C . This investigation proved that, the solar car
ventilator can provide a comfort level reaches to 18% of reduced temperature inside a car.
• comfort for passengers on their initial entrance to the vehicle
• reduction of temperature inside the car compartment will reduce the energy consumption of the
AC system.
• Very efficient electronics should be used to have long life of usage since it is working in a very

Supervised by: Dr. Ibrahim Alsaidan
Date: 9th April. 2019 (392)Abstract
Growing concern for environmental issues poses significant chance to the utilization of distributed renewable energy resources in power system. The
intermittent nature of renewable energy, however, put power system at risk. Microgrid is introduced as an efficient strategy to integrate renewable energy
resources safely from various locations within the distribution network. Distributed energy storages are considered as a vital component of reliable cost-
efficient microgrid. Distributed energy storages applications in microgrid include but not limited to energy arbitrage, reliability improvement, resiliency
enhancement, and ancillary services. To ensure an acceptable economic and technical performance, distributed energy storage must be optimally sized and
placed. This project investigates the concept of microgrid and discusses the impact of integrating distributed energy storage on the microgrid operation.
Moreover, a battery energy storage design model that can be used to determine the optimal size of the installed battery energy storage is developed.
Project Objectives
• To define microgrid and investigate its benefits to power system.
• To study energy storage types and applications.
• To study the battery energy storage applications in microgrid.
• To develop a design model for battery energy storage.
• To determine the optimal design for the installed battery energy storage.
Fig.1. Proposed model.
Motivation
• The battery energy storage (BES) is an essential component for
microgrid operation and control [1]. However, the high investment cost
of BES limits its installation in the power system.
• Finding the optimal size of BES, which is related to its investment cost,
will ensure reliable and efficient installation of BES.
Description
In this project, BES design model is developed that enables microgrid
planners to determine the optimal size (i.e., power rating in kW and energy
rating in kWh) of the installed BES in their system. Mixed Integer Linear
Programming (MILP) is implemented to formulate the developed model.

Design and Implementation of Photovoltaic –Thermoelectric(PVTE) Dual Axis(DA) Tracking System
WALEED ABDUALRAHMAN ALTUWAYJIRIMOHAMMED SALAH ALHIGRES
Supervised by: Prof.Arvind Tiwari
Date: 9th April, 2019 (392)Abstract
This project describes the design and implementation of an energy efficient solar tracking system from a normal mechanical single axis to a
hybrid dual axis. For optimizing the solar tracking mechanism electromechanical systems were evolved through the implementation of different
evolutional algorithms and methodologies. To present the tracker, a hybrid dual-axis solar tracking system is designed, built, and tested based on
both the solar map and light sensor based continuous tracking mechanism. These light sensors also compare the dark and cloudy and sunny
conditions assisting daily tracking. The designed tracker can track sun’s apparent position at different months and seasons; thereby the electrical
controlling device requires a real-time clock device for guiding the tracking system in seeking the solar position for the seasonal motion. So the
combination of both of these tracking mechanisms made the designed tracker a hybrid one. The power gain and system power consumption are
compared with a static and continuous dual axis solar tracking system. It is found that power gain of hybrid dual axis solar tracking system is
almost equal to continuous dual axis solar tracking system, whereas the power saved in system operation by the hybrid tracker is 44.44% compared
to the continuous tracking system. Photovoltaic (PV) systems being one of the primary tools to convert solar energy into electrical energy also have
inherent losses which lead to lesser electrical output and less efficient system. In recent years researchers have introduced thermoelectric modules
with PV so as to improve the efficiency of the PV and electrical output of the system. Various researchers have designed, developed and compared
different PV system by either increasing the input energy by means of incorporating lenses and mirrors or by reducing losses by incorporating
collectors into the PV system. In this project, we will design the PVTE system incorporating dual axis(DA) sun tracking system to enhance the
electrical output and hence obtain better efficiency from the system.
Objectives and MotivationsThe objectives of this senior design project (SDP) are:
i) To design and implement a dual axis tracking using a controller.
ii) To increase the efficiency of the panel by using thermoelectric(TE).
iii)To Increase the irradiation on the panel by using the tracking system.
.Advantages• More efficiency.
• More irradiation on PV panel.
• More output power.
Conclusion
We decided to work on hybrid photovoltaic thermal systems (HPVT) to increase theefficacy and cool of the PV, we chose this method because it has better performance in termsof energy, life cycle assessment and being economical to the PV only systems in a standaloneconfiguration. From all the (HPVT) methods we chose to work on the thermoelectric coolers(TEC) have more promising waste heat recovering feature and the output is entirely electricalin nature, which could be used directly for enormous application and thus makes the systemmore economical in terms of energy production. We chose our design based on the easiness ofimplement, the elements should be at suitable prices and it should be flexible. In all thetracking system available dual-axis tracking system increases the output power by 25-40%.Hence, we intend to compare the performance of our hybrid (PV – TE) dual axis trackingsystems performance with a single axis and fixed frame PV-TE system.

CONSIDERING GENERATION RATECONSTRAINTSNader Ali Alarfaj
Ibrahim Sulaiman AlsallalSaleh Mohammed Alsaleem
Supervised by: Prof. Ibraheem Nasiruddin
Date: 9th April, 2019 (392)AbstractOver the last few decades, enormous changes have been witnessed in power system structure and therefore, their operational and control problems became very
complex and difficult. Operating a power system in interconnected fashion has aggravated the complexity further. To provide good quality of electricity to
consumers, an effective and reliable control schemes are required to regulate the system frequency and voltage levels to their nominal values following the load
disturbance in the system. The present SDP aims to design PID structured controllers to regulate the frequency of a two-area interconnected power system
consisting of reheat thermal turbines in the wake of step load disturbance in the system. As generation rate constraint(GRC) is generally imposed in real time
power system operation on generators, the effect of GRC on system dynamic performance is incorporated in the study. From the investigations of the system
dynamic plots obtained for step load disturbance in one of the areas, it is revealed that the designed regulators/controllers are very effective to mitigate the
deviations caused due to disturbance. Moreover, it is shown that incorporation of GRC has resulted in the deterioration in system dynamic performance which
needs the design of advanced controllers to handle the system dynamics effectively.
ObjectivesThe main objectives of this senior design project (SDP) are:
i) To develop linearized model of the system without generation rate constraints on electric power generators.
ii) To develop non-linear power system model of the system incorporating generation rate constraints on electric power generators
iii) To design PID structured load frequency controllers for both power system models developed in (i) &(ii)..
iv) To implement the developed PID structured load frequency controllers in the wake of different load disturbance conditions and to investigate the dynamic
system performance.
v) To demonstrate the effect/effectiveness of designed structured load frequency controllers.
ConclusionsThe investigations carried out from the dynamic response plots obtained with the implementation of designed regulators in the wake of step load disturbancein the system. These are shown above in Figs. 2-6. From the investigations of these dynamic response plots, it is inferred that frequency regulators designedusing Z-N tuned approach are very effective in eliminating the steady state error in responses and settling the deviations caused by load disturbance in fewseconds to zero. offer much better system dynamic response as compared to that offered when controller gains are obtained using trial and error approach interms of least overshoot and settling time. However, the presence of GRC has resulted in the deterioration in system dynamic performance which needs thedesign of advanced controllers to handle the system dynamics effectively.

DescriptionsThe PID controllers are designed for the load frequency control of a two-area interconnected power system consisting of reheat thermal plants. The two areasare interconnected by means of AC transmission line. First the transfer function model of the system is developed considering the generation rateconstraints(GRC) on generators. Following this the PID gains of frequency controller are obtained using Z-N technique. The designed frequency regulator havebeen implemented to control the generation so that it matches the varying load demand while keeping the frequency and tie-line interchanges at their schedulevalues even in the presence of GRC. Because the interconnected power system consists of identical areas, the dynamic response plots are obtained fordisturbance in area-1. The system dynamic response plots for ∆F1, ∆Pg1, ∆Ptie, ACE1, ∆Xg1 considering 1% load disturbance in area-1 are obtained with variousdesigned frequency regulators using SIMULINK Toolbox.

In last few decades, electric power demand is increasing at a very fast pace and the power industry has witnessed many structural and technological
changes. The stability of power system has become more difficult these days as consumption of electrical power fluctuates randomly. Due to limited
resources of power generation, the transmission lines getting heavily loaded and facing the various important issues like; stability, voltage sag, and
reactive power. The FACTS technology is essentially proved in tackling these issues and able to alleviate them efficiently. Flexible alternating –
current transmission systems (FACTs) devices usually install power electronic devices at the appropriate places of the existing AC systems to enhance
controllability and increase power transfer capability. In this project, the various reactive power compensation techniques based on FACTS devices
like thyristor controlled phase shifter (TCPS), static var compensators (SVC) and Static Synchronous Series Compensator (SSSC) are considered for
design and implementing the voltage control schemes in the power system network using Power System Analysis Toolbox (PSAT) via the link with
MATLAB. Simulation models are developed for IEEE 6 bus system with and without FACTS devices.
Key Words: FACTs, Reactive Power, Voltage Control, SVC, SSSC, TCPS .
Objectives and Motivations
The objectives of this senior design project (SDP) are:i) Voltages at the terminals of all equipment’s of the system should be
within acceptable limits.ii) System stability is enhanced to maximize the utilization of the
transmission network.iii)The reactive power flow is minimized to reduce I2R and I2X losses
to a practical minimum.iv) The voltage may be controlled and maintained by proper designing
and implementation of FACTs devices at the vulnerable load buses.
Conclusion:
The design and implementation of different voltage control methods based
on FACTS devices have been carried out in details. The production and
absorption of reactive power by various sources also presented in this
project report. The importance of the maintenance of voltages at different
locations in the power system network has been elaborated in the report and

Supervised by: Dr.Abdelraheim Emad
Date: 9th April. 2019 (392)
AbstractAn industrial robot arm usually ends with an end-effector. A common task of an industrial robot arm is to pickup certain object, hold it at a desiredconfiguration and move it between specific locations. The process of picking up and holding is the main task of a gripper.Many QEC-SDPs dealt with the subject of speculation of the design and implementation of a robot arm or robot cell. This project, however, may beconsidered as the foresight for the design, manufacturing and implementation of a mechanical gripper in QEC. The proposed gripper-model consists oftwo mating four joint mechanisms that can catch (pick up) and hold objects. The gripper is driven by single servo-motor and gear system. The idea of theproject was stemmed from “the need to catch an object when it enters the target zone of the gripper and hold it for a while”. This idea was behind thecontrol strategy, which may be summarized as that the target area of the gripper is to be scanned by a position sensor to detect if the object exists or not.Upon the existence of the object; the controller signals the motor to move such that the gripper ends (jaws) clip the object, hold it for a specific delaytime then leave it. This delay time simulates as if the gripper was attached to an arm and the arm is moving it to another destination. The control systemis based on the use of simple closed-loop control topology by programming an ARDUINO controller to control the motion of the servo motor.The conceptual design technique is utilized during the progress of this project. This includes the use of Kepner-Tregoe Decision Analysis (KTDA) techniqueto select all components. The project shows the dynamic analysis of the four joint mechanism. The project also contains the steps of manufacturing a pre-
gripper model by using the 3d-printer facilities. The experimental tests conducted to test the system gave quit satisfactory results.
Objectives and Motivations:
• Conceptual design application
• Design a system to move double mechanisms to pickup an object.
• Apply gained knowledge from ME340-ME467-EE318- GE211 to automate the operation of the designed system.
• 3D printing
• Implementation, assembly and running experiments.
Description:
The gripper system consists of single servo motor, Position sensor, two 4-joint mechanisms, each of which provides single degree of freedom, and Arduino chip. The misc. parts are: bolts, screws, base and wires.
Conclusions and Recommendations:
• Mechanical gripper model system was designed and implemented successfully
• The system need to more research to make its response more accurate.
• Using control topology to control closed loop for the current model.

MEASURMENT DUE TO PUMP CAVITATION
Abstract
Cavitation is recognized to be one of the interesting phenomena that occur in the pumping
system. The purpose of this work is to design a test-rig for vibration diagnosis of pump
cavitation. To achieve this purpose, a centrifugal pump was selected with the appropriate
specifications that will enable the diagnosis of cavitation using vibration signals. The
selected pump has been modified by inserting a new driving unit with a speed controller.
A reversible engineering process has been conducted to design the shaft in order to
check the pump shaft capability to handle the new modification on the pumping system.
The measurements are conducted on a test setup equipped with two accelerometers and
one sensitive microphone to correlate their output signals with the emerged cavitation.
Description
The overall pumping system setup which consists of a centrifugal pump with transparent
plastic cover, induction motor, elastic coupling, deep groove bearing, VFD, pressure
gauges, a tank with the capacity of 20 liters, accelerometer sensors, and manual valves
Conclusion
The test rig is designed to be used in education and research purposes. During
the design process, the minimum requirements to achieve the test-rig objective
are defined. Although the good correlation between the velocity spectrum of
vibrations and the sound spectrum of the generated cavitation, some irrelevant
reverberated frequencies of cavitation bubbles smeared the sound spectrum.

Abstract
Erosion – corrosion (E-C) of metallic materials designates the material degradation where mechanical wear by solid particles, liquid or the
combination of both processes interacts with corrosion caused by dissolution or surface oxidation. E-C phenomenon has caused many problems
resulting in a material loss and equipment failure. Therefore, the phenomenon received an increasing attention from researchers all over the world. The
main difficulty when trying to get information about the E-C is the method by which the experiments can be performed. The objective of this project is to
design and fabricate a test rig for E-C experimentation. Jet impingement set up had been designed and manufactured. All design procedures and
manufacturing steps were followed. Furthermore, the impact of the project on society, ethics, and environment were considered. Finally, the cost
estimation of the final product was done.
Objectives and Motivations
• Design and fabrication of test rig to generate Erosion - corrosion in the laboratory domain.
• Experimentally study of Erosion-corrosion effects on different materials.
• Study the effect of different parameters (time, velocity, concentration and impact angle) on erosion corrosion resistance.
• Calculate Erosion-Corrosion rate through weight loss.
Description
Erosion-Corrosion test rig (apparatus) consists of a tank contains a mixture (slurry) of water and solid particles (silica sand). A mechanical stirrer
is used to guarantee the homogeneity of the slurry. A pump is utilized to raise the slurry to attack the tested sample with various velocities. The
main idea is to prepare the homogenous slurry of water with specific concentrations of solid particles inside the tank then pumping this mixture to a
nozzle to impact the sample which is set in specific adjustable angles. The design allows the slurry to circulate continuously during the experiment.
The velocity can be measured by a flow meter supplied to the apparatus. The weight loss of samples is calculated as an indication of erosion corrosion
rate.

Supervised by: Associate Dr. Saad Mukras
Date: 8th April. 2018-2019 (392)
AbstractIn recent years, the quadcopter has gained popularity in many fields. This is because of the simplicity of mechanics thathas been used in this kind of copter. It is very beneficial, but it has some limitations. For example, the time of flying andthe range that can reach it in flying. So, this project will seek to address this problem of flying time and trying to extendthis time by designing a quadcopter that draws additional power from solar panels environmental reasons.
Objectives and Motivations• Design the appropriate structure that fit with placing the solar cells that would extend the range of a quadcopter. • Construct the quadcopter with a suitable frame.
DescriptionQuadcopter is very popular nowadays; and it is good in a number of applications. For example, it used in filmingmovies, military field, surveillance, search and rescue, construction inspections and several other applications. It ishowever limited in the ranges of the flying time. It is consuming a lot of power, and thus the battery can not stay for longtime. In this project, we are laying the groundwork for the design of a quadcopter where the flying time range is extendedusing solar energy. The aluminum metal chosen for this structure, because it is light in weight and strong. We did thecalculations of stresses and deflection to see if the metal can carry the loads of motors and the other components. We endwith relations of deflection with height and width. These relations helped in choosing the appropriate size of thestructure.
Conclusion and recommendation• The design of structure should be in way that allow more solar cells to place on it. • The material of the structure and the solar system should be light in weight, to reduce the power consumption as
possible as can. • The solar system should be efficient, to get the maximum power with less weight. • The stress calculations should be done correctly, it is better to use ANSYS software to inform your calculations and see
where is the maximum stress.

PORTABLE AIR CONDITIONING SYSTEM USING PHASE CHANGE MATERIALS
Ahmad AlodahSufyan Alqurban
Supervised by: Dr. Ahmed M. Alshwairekh
Date: 9th April. 2018-2019 (392)Abstract
The objective of this Senior Design Project (SDP) is to design and implement a novel idea in the area of air conditioning (AC). The aim of designing thenew AC is to make it compact and portable. There will be no refrigeration cycle embedded within our design, rather the use of phase change materials(PCM) will be implemented. Water will be used as the phase-change material since it is the most affordable type of PCMs. The AC will be used for aperiod of 3 to 8 hours depending on several factors such as the mass of the PCM used, the inlet air temperature, and the mass flow rate of inlet air. TheAC is composed of the body which is insulated, a fan, and the PCM. The air is moved by the fan, then the air exchange heat with the ice and thereforethe temperature drops and the ice melts after a certain period. The AC is designed to be portable and to work within a small personal area.
Objectives And Motivation
The motivation for this project is the kind of weather we have in the Kingdom of Saudi Arabia (KSA). In the summer season, The air temperature under direct sun light may reach to 50℃ easily. This kind of extreme temperature affect the performance and the daily functions of personal working outside. The use of regular air conditioners will not be practical because of the large size and the use of electricity. Hence, the idea of portable air conditioners are born.
Objectives:
1. Design a portable AC2. Reduce the air temperature3. Reduce the use of PCM
Description
The portable AC consists of three main parts, 1- the body of the AC. 2- the fan. 3- the PCM or the ice. The body of the AC should be thermally insulated to avoid any heat loss to the surroundings and to prolong the life cycle of the PCM. The fan is used to move the air from the surrounding environment to the inside of the AC body. As the air is moved inside, the air will exchange heat with the ice. Therefore, the temperature of the air will reduce. There are several factors that affect the reduction of the air temperature such as the mass flow rate of the air, the temperature of the inlet air, the mass of the ice contained in the body of the AC, and the arrangement of the ice inside the container. Also, the exit opening of the air can have several orientations and design, we have chosen a simple round tube to act as the outlet of the AC. The fan has a potentiometer attached to it so that the speed is variable. In the analysis of the AC, several factors can be studied. However, the most important factor are been considered such as 1- The speed of the inlet air. And 2- The mass of the PCM or ice. It is desired to have a small compact AC. Therefore, the mass of the PCM is an important factor to be considered. So, the mass of ice was changed from 1 kg to 5 kg with an increment of 1kg. Also, the speed of the inlet air was varied three times. The exit air temperature was monitored with time. The ultimate aim is to have the exit air temperature as low as possible for the longest period of time with the lowest possible amount of ice.
Results
Conclusion and Recommendations
In our design, the ice was placed in the bottom of the AC container. Therefore, the air was not having a perfect contact with the ice. Therefore, the arrangement of the ice is an important factor to be considered. It is recommended that the ice be raised over the bottom and the container should be divided so that the air can have a longer time in the AC. The longer the air is in the container, the more the temperature drop we have. However, this deign will give rise to a higher pressure drop, therefore, the velocity of the air should be increased to overcome the increased pressure drop from the different arrangement of the ice.
The exit air temperature was monitored over time for several cases. Sample cases are presented below.

Abstract
In this Senior Design Project (SDP) it is aimed to develop and test a cooling water system for residential roof tanks. Firstly a short review of storage
tanks is presented. Then the new types of tanks introduced are described. After that the elaboration of the cooling water system is performed. The system
consists of a 4-layer poleythelyne tank painted with a special insulating layers. For testing the new system, a second similar and regular tank is used.
The two tanks are filled with water and exposed to the sun temperature measurement. Measuring is each two hours starting at 7a.m.Unfortunately the
weather is still relatively cold for testing. However we expect to have good results and we just wait for the ambient temperature to increase for testing.
Motivations and Objectives
storage of potable water is needed for most of world population. Overhead water tanks are used to solve this crisis but their exposure to sun radiation
during hot days increases water temperature to the extent that it becomes unsupportable for bathing and washing. Therefore it is very important to develop
a cheaper cooling storage tank that keeps the water temperature within the acceptable range.
System description
Water Storage tanks have been significantly developed.
They are changed from stone-belt type, passing by
concrete and metallic type to reach the actual well treated
plastic type [1, 2 ] as shown in the figure 1.
Figure 1 water storage tank evolution
Eminent aspects of the developed cooling system
The developed cooling tank is made from a 4-layer Polyethylene Water Tank which has good insulation aspect, painted with extra insulating layers (prepared from a mixture of calcium carbonate and white glue ). This double insulation in addition to the light weight , affordable cost, easy installation, anti- corrosion, .. Form the distinguished features of the new cooling system.Concerning the system testing for keeping water cooler than ordinary tanks , the new system and another similar regular tank are filled with water in order to expose them on the college roof to solar radiation. Then water temperature will be measured at the same time in both tanks each two hours . Unfortunately the weather is still not enough hot to conduct the experience but we expect considerable difference between the temperatures of water in the two tanks. The two tanks are shown in fig.2
Conclusion and recommendationsthe project cost is not high and it is very essential for keepingwater cool in the hot Gulf summer season . Also the project shouldcontinue when the summer becomes very hot in order to assessthe new system.

Sewerage system is the infrastructure that collects, treats, and safely dispose the wastewater generated from residential, commercial, and industrial areas. Its main
components consist of a network of sanitary sewers, manholes, pumping stations, and wastewater treatment facilities. In this senior design project, a sanitary
sewerage system and wastewater treatment plant has been designed for a fully developed residential area in Buraydah City. Design of sanitary sewerage system
includes estimation of population served and peak sewage flows to design the sanitary sewers. Velocities in the sewers are equal or higher than the self-cleansing
velocity of 0.6m/s. Invert levels are calculated for upstream and downstream of each sewer. Locations of lift stations are identified for the sewers deeper than 15 m.
A complete hydraulic statement has been developed on Excel worksheet. Longitudinal profile for the longest sewer is also developed. Final disposal station is
designed to discharge the collected water into the wastewater treatment plant (WWTP). The components designed for WWTP consist of bar screen, grit chamber,
primary clarifier, rotating biological contractors (RBC), secondary clarifier, sand filter, and chlorination unit. The treated wastewater can be recycled for agriculture
purposes.
Key Words: Sanitary Sewer, Sewerage System Design, Self-cleansing Velocity, Invert Level, WWTP
Objectives and MotivationsThe objectives of this senior design project (SDP) are:
1. Estimation of design flow for sanitary sewerage systems.
2. Hydraulic design of sanitary sewerage system
3. Design of wastewater treatment plant for a residential area in the city of
Buraydah.
The motivation of our Senior Design Project (SDP) was to design a sanitary
sewerage system and wastewater treatment plant for safe disposal of
obnoxious wastewater. The treated wastewater recycled for agricultural
applications follows the sustainability objectives of Vision 2030 of Saudi Arabia.
Conclusions • A sanitary sewerage system for a residential area (1,600,000 m𝟐) located at the North of Buraydah was
designed. Sanitary sewage system consisted of 285 sewers, 284 manholes, and a final pump station.
• Due to rolling topography, the depth of trenches were found to be deeper than 15m at certain locations. To
avoid extra cost for deeper trenches, 3 lift station have been proposed.
• 96 drop manhole were provided at the manholes where the difference between invert levels of sewers was
found to be more than 0.6m.
• WWTP consisting of four main treatment phases preliminary, primary, secondary and tertiary treatment levels
sufficiently meets the required standards for recycling of wastewater fro agricultural applications.
