Chapter - 1

Development of New Civil Enclave at Kanpur Air Force Base

1.1 Background

Kanpur Air Force Base is an airport that was originally designated for the

Indian Air force. In the 1970s, flights operated from this airport regularly to

Delhi, Ahmedabad, Kolkata, Banglore, Chennai, Pune and Mumbai. However

passengers of Kanpur and surrounding developing cities have an opportunity

to get better air connectivity because of its close proximity to CCS

International Amausi Airport in Lucknow, for taking a flight to other Indian

cities or overseas. The Civil Air Terminal of Kanpur Airport was re-opened in

December 2004 and since then regular flights are operational on this airport.

This airport serves Kanpur, Unnao, Etawah, Kanpur Dehat, Hamirpur and

Fatehpur in Uttar Pradesh.

It is at a distance of 10 km from Kanpur city. Other nearest operational

Airports are Lucknow, which is located at distance of 86 Km.

Chapter - 2

HVAC & BMS System for the Proposed Terminal Building

2.1. General

This Chapter outlines the design features, basis of design, estimated

requirements etc. of the HVAC System at proposed terminal building.

The proposal for installing microprocessor based control system (BMS) is also

outlined in this Chapter.

2.2 Design Considerations

The system proposal is designed to fulfill the following objectives:

Low capital cost.

Energy efficient throughout the varying load patterns

Minimum power demand.

Providing required Indoor air quality (IAQ) with reduced operating cost.

Maximum flexibility of operation.

Use of highly responsive control system (BMS) to optimize system

functioning.

2.3 Energy Efficient

The air conditioning systems operate between a minimal demand of 40% and

up to a maximum demand of 95% for a major part of the year.

Hence, the selection proposed is such that the overall power requirement

remains consistent with the demand, avoiding all possible waste.

2.4 Flexibility

The use of Air cooled chilling units have been proposed instead of water

cooled chillers. This will avoid use of cooling towers and condenser water

pumps, thereby reducing by nearly 40% the number of equipments which

have to be operated and maintained.

Page 12: Pre-Feasibility Report (PFR) · Development of New Civil Enclave at Kanpur Air Force Base, Kanpur, U.P. 2 Navigation Aids NDB : AVAILABLE (IFA) ILS : Available (Cat -I) DVOR : Available

Development of New Civil Enclave at Kanpur Air Force Base, Kanpur, U.P.

11

The chiller will be fitted with air cooling pads to reduce power consumption

and save 80% water as compared to water cooled system, the cooling pads

will be used whenever Ambient temperature crosses 35°C.

The use of air cooled chillers will thus simplify operation and also avoid

worrying about availability of water in cooling towers at all times.

There will be separate pumps for secondary circuit.

In addition each floor will have independent Air handling Units (AHUs).

This will ensure that the equipment in operations is as per demand without

any wastage of power.

2.5 Control System

It is proposed to use microprocessor based control system (BMS) to optimize

plant operation and minimize running costs.

The various systems are selected carefully to provide maximum benefits at a

reasonable cost.

The BMS will also be used to integrate other services and control external

lighting and monitor other services.

2.6 Salient Feature of Air-cooled Chilling Units

The air-cooled chillers are packaged and factory assembled and consists of

the following components:

Screw / Scroll compressors.

Shell and tube chiller.

Condenser coils

Condenser fans

Control Panel

Weather proof housing.

These chillers are designed and manufactured for outdoor installation either

on the ground or on the roof, where they can get un-hindered supply of fresh

air.

2.7 Screw Compressors

The screw compressors are nearly as efficient as Centrifugal Compressors

and consume approx. 0.71 IkW per ton to 0.73 IkW per ton in the proposed

capacity range. These compressors have very few moving parts. Hence their

wear and tear is less and this reduces the maintenance costs.

These units are currently being imported or assembled in India from Imported

components and they come equipped with a microprocessor based control

panel. Hence, the output is automatically matched with the demand. Thereby,

these units result in further power saving. They can be used efficiently down

to 1/3 of the rated output.

2.8 Control System

It is proposed to install Microprocessor Based DDC Control system, (BMS) for

operating the HVAC plant, water supply system, common lighting and for

monitoring other systems. The use of BMS has the following advantages.

a. The sequencing of the chillers and pumps will be done automatically as

per the load requirement, thus avoiding wasteful operation.

b. The plants will operate automatically as per programmed schedule the

controllers will estimate the actual requirement on any particular day

depending on outside temperature and accordingly decide the lead time

required to achieve design inside conditions, in all areas, at the start of

offices.

c. All these feature help to bring down the energy consumption by 10 to

15%.

d. All standby pumps are rotated automatically to provide equal wear and

tear and reduce fatigue.

e. All external lighting and common area lighting are controlled

automatically to save energy.

f. The water supply system is controlled and operated as per requirement

without any wastage.

g. All other services are monitored.

2.9 Estimated AC Load Requirement

At the proposed civil enclave 3X200 TR (1 Working +1 Standby) air cooled

screw chillers are proposed.

2.10 System Concept

The main chilling station will have multiple screw chillers.

It is proposed to have strip heaters in supply air ducts for winter heating.

A standby chiller is also proposed.

The system has been designed on the basis of many areas having high heights.

Further, it is proposed to install nozzle type diffusers for long throw of air from such AHUs.

The A.C. plant will be placed outside in service yard along with other electric and water services.

2.11 Building Management System (BMS)

It is proposed to provide a Microprocessor Based Building Management and

control system (BMS) for HVAC system and other services to create an

intelligent building.

4.7 Sewerage Treatment and Disposal

As per water balance diagram, 107 kld sewage will be generated during the

operation of new terminal building which will be treated in STP of 125 kl/day

capacity.

4.8 Sewage Treatment Plant

Sewage generated from the airport will be treated in well-designed Sewage

Treatment Plant (STP). It is proposed to installed Moving Bed Biofilm

Reactor (MBBR) type sewage treatment plant of 125 kl capacity.

Design of STP

Approximately 125 kl per day sewage/waste water will be generated from the

proposed airport. Sewage will be collected and treated in well-designed

sewage treatment plant. After meeting stipulated standards, treated waste

water will be utilized for flushing purpose, irrigation of greenery and

landscaping.

Details of Sewage Treatment Process

The sewage from the proposed airport shall be collected by gravity into the

collection tank/equalization tank of Sewage Treatment Plant (STP) via

perforated screens to prevent the large particles into system. In equalization

tank, pH and temperature of incoming sewage will be equalized. The sewage

from equalization tank will be pumped to Moving Bed Biofilm Reactor (MBBR)

reactor for biological treatment, where required quantity of air in presence of

MBBR system will be supplied to meet the oxygen requirements by mean of

blower and fine bubbles air diffusers. After MBBR reactor, sewage will flow by

gravity to settler (tube type) where sludge will be settled at the bottom due to

Page 20: Pre-Feasibility Report (PFR) · Development of New Civil Enclave at Kanpur Air Force Base, Kanpur, U.P. 2 Navigation Aids NDB : AVAILABLE (IFA) ILS : Available (Cat -I) DVOR : Available

Development of New Civil Enclave at Kanpur Air Force Base, Kanpur, U.P.

gravity. This settled sludge will be recycled through sludge pump to MBBR

reactor to meet the mixed liquor suspended solids (MLSS) requirement,

excess sludge will be discharged through filter press for final disposal. Final

discharge of waste water from settler will be collected in chlorine contact tank,

where some chlorine will be dosed for disinfections of treated waste water.

Then, treated sewage will be pumped for tertiary treatment through duel

media filter or it will be passed through or it will be passed through Ultraviolet

(UV) disinfection system. Treated sewage will meet the norms prescribed by

State Pollution Control Board and will be utilized for flushing, HVAC and for

irrigation of greenery & landscaping purpose. Treated wastewater will not be

discharged outside the boundary of proposed airport.

Design Parameters

Design parameters for proposed STP are given below:

Sl. Parameters Inlet Outlet

1. BOD 300 mg/l Less than 20 mg/l

2. COD 400 mg/l Less than 150 mg/l

3. Oil & Grease 50 mg/l Less than 10 mg/l

4. TSS 200 mg/l Less than 50 mg/l

5. PH 6.5-8.5 mg/l 6.5-8.5 mg/l

No treated waste water will be discharged outside the proposed civil enclave.

Unit wise description of the proposed STP is given below and shown in

Figure 4.2.

Screen Chamber

Prior to the actual treatment of the wastewater, a screen chamber will be

provided. In this chamber removable type mechanical bar screens will be

provided for removal of various large size elements, such as paper, cloth,

plastic etc, etc, which may hamper the satisfactory functioning of subsequent

units of the STP, if not removed at early stages.

Equalization Tank

As the quantity of the flow is non-uniform in nature, an equalization tank will

have to be provided. By the provision of an equalization tank, wastewater

characteristics will become homogeneous in nature and, therefore, better

treatment can be achieved in the subsequent units of the STP. Diffused

aeration will be provided in this tank to stir the contents of the tank completely.

MBBR Reactor (Biological Treatment)

Moving Bed Biofilm Reactor (MBBR) technology employs thousands of

polyethylene biofilm carriers operating in mixed motion within an aerated

wastewater treatment basin. Each individual bio carrier increases productivity

through providing protected surface area to support the growth of

heterotrophic and autotrophic bacteria within its cells. It is this high-density

population of bacteria that achieves high-rate biodegradation within the

system, while also offering process reliability and ease of operation.

This technology provides cost-effective treatment with minimal maintenance

since MBBR processes self-maintain an optimum level of productive biofilm.

Additionally, the biofilm attached to the mobile biocarriers within the system

automatically responds to load fluctuations.

The bacteria/activated sludge grow on the internal surface of the carriers. The

bacteria break down the organic matter from the waste water. The aeration

system keeps the carriers with activated sludge in motion. Only the extra

amount of bacteria growth, the excess sludge will come separate from the

carriers and will flow with the treated water towards the final separator. The

system can consist of a one stage or more stage system (see underneath

schedule), depending on the specific demands. The specific bacteria remain

in their own duty tank because of the fact that the carriers remain in only 1

tank, protected by screens.

A bio-film develops on the media, which move along the effluent sewage in

the reactors. The movement within the reactors is generated by providing

aeration with the help of diffusers placed at the bottom of reactors. This thin

film on the media enables bacteria to act up on the bio-degradable matter in

the effluent sewage and thus reduce the BOD/COD content in presence of

oxygen from the air used for fluidization. Aeration will be done with the help of

twin lobe blowers. The MBBR reactors will increase the oxygen content of the

sewage and thus, will help in the growth of the micro-organisms required to

reduce the BOD. These micro-organisms will consume the organic matter and

will convert it into active biomass, better known as sludge. The waste water,

laden with sludge, will be transferred to tube settler for sludge separation.

Secondary Settling Tank Followed by Pre filtration Tank

The sludge formed will settle in the secondary settling tank followed by pre

filtration tank. The settled sludge will be discharged in the Sludge Collection

Tank and would be dewatered using sludge press. The clear supernatant from

the outlet of the tube settler will be discharged as treated waste water and will

be passed on to further treatment for final polishing. HDPE/PVC low

maintenance tubes will be provided for trouble free operation of the tube

settler.

Sludge Filter Press

The sludge from the settling tank of the STP will be collected in the tank and

will be treated in the sludge press. This will be 24 plates CI sludge press

completes with its pump and accessories. In sludge press, the sludge in the

form of liquid slurry is fed into the press and dry solid cake of sludge is taken

out from it. These dry cakes are used as manure for green belt and

landscaping.

Pressure Sand Filter

For final polishing of the treated waste water, a Pressure Sand Filter (PSF)

will be provided. The PSF comprises of a MS Vessel having filtering media

sand topping for filtration of supernatant treated sewage water and thus

ensuring clarity of water.

Activated Carbon Filter

For tertiary treatment, an Activated Carbon Filter (ACF) will be provided. This

will be MS constructed tank in which activated charcoal/carbon will be filled as

adsorbing media. This will not only adsorb impurities but will also act as the

polishing tank for the final treated waste water. The resultant water shall be

clear, odourless and will be reused for horticulture purpose.

Ultraviolet (UV) Disinfection System

Ultraviolet (UV) disinfection will use a UV light source. UV-rays are energy-

rich electromagnetic rays that are found in the natural spectrum of the

sunlight. They are in the range of the invisible short wave light having a

wavelength ranging from 100 to 400 nm. can pass through a flow chamber,

and UV rays are admitted and absorbed into the stream. When ultraviolet

energy is absorbed by the reproductive mechanisms of bacteria and viruses,

the genetic material is rearranged and they can no longer reproduce. They

are therefore considered dead and the risk of disease has been eliminated.

UV plant will have following features:

Stainless steel construction

Single lamp

Solid Waste Management

5.1 Solid Waste Generation

It is estimated that approx. 365 kg/d solid waste will be generated from the

airport. From the new terminal building, waste will be generated in the form of

paper, plastics, polyethylene bags, and food waste, etc.

5.2 Solid Waste Management

The following measures will be taken for management of solid waste during

operation phase of proposed airport.

Solid wastes management will be carried out as per Solid Waste

Management Rule, 2016.

Wastes shall be collected in designated waste bins based on their types,

placed at the strategic locations.

The solid waste handling and disposal services will be outsourced to

authorized agency to ensure disposal of solid waste generated from the

proposed airport. Solid waste generated in the aircrafts will also be disposed

off at the designated waste collection points from where the agency will pick

up the garbage bags. The agency will collect the garbage from designated

bins, which will be spread over the area of proposed airport. The wet garbage

of the aircrafts comprising of leftover food in the tray from the security gates of

flight kitchens will be disposed off at the specified places.

The collected garbage will be transported in covered container and will be

arranged to dispose off after segregation of recyclable wastes as per

provisions of Solid Waste Management Rule, 2016. After collection of

garbage, garbage bins will be disinfected every day by sprinkling disinfectant

powder by the agency. Weekly washing of garbage bins will also be carried

out by this agency.

After collection of waste, solid waste management plan to be followed by

authorized agency is as given below:

• Segregation of recyclable and non-recyclable wastes.

• Disposal of recyclable wastes for recycling.

• Composting of biodegradable organic of wastes for captive use

• Disposal of segregated wastes to common municipal waste landfill Site

Energy Conservation

6.1 Energy Conservation Measures

During design and construction of new terminal building at the proposed Civil

Enclave at Kanpur necessary measures will be taken for conservation of

energy in line with “Energy Conservation Building Code –2017” and “National

Building Code 2016”. The important energy conservation measures proposed

for new terminal building are described below:

Terminal building will be designed and constructed for GRIHA Rating 4

star,

Use of Energy Efficient building material & glass,

Use of LED lamps instead of GLS lamps,

Use of Solar Backed up Light Emitting Diode Lamps instead of par lamps,

Energy efficient HVAC system,

Solar passive techniques for terminal building,

Use of 5 star BEE energy efficiency rating electrical equipments,

Microprocessor-based Building Management System (BMS) will be

installed for minimization of energy consumption,

Automatic lighting on/ off control system will be provided in the airport area

for optimum utilization of energy.

It is proposed that 100 KW solar power generation plant will be established at

the airport to produce clean energy.

By adopting above measures about 30% energy will be saved.
