As I write this, Hurricane Michael has struck the Florida panhandle as a category 4 storm. In the past couple months, we have seen the extreme forces of nature with deadly consequences from Hurricane Florence, an earthquake in Japan, and an earthquake and tsunami in Indonesia. We normally expect the occurrence of tornados in the Midwest of the United States, but even

Richmond, Virginia, where I live, experienced a deadly tornado, spun off from Florence as the hurricane moved north. While tornados can approach with little time to prepare, hurricanes are tracked through the National Oceanic and Atmospheric Administration (NOAA) Hurricane Center providing adequate time to prepare. Emergency management and other local agencies are valu-able resources for readiness when natural disasters strike,

Message From The President

Helen CerraPresident

offering precautions for the public and workplaces. What about cooling towers? Prepare your cooling tower for anticipated high wind events by locking out the electri-cal supply to mechanical equipment, securing fan blades from spinning, fastening basin covers, and securing any loose elements or chemical containers. Our CTI member manufacturers and suppliers can provide additional infor-mation to ensure your equipment survives storm forces. In addition, Technical Paper 17 presented in 2017 discussed the design of cooling towers for sustaining high winds. As Thomas Fuller said, “In fair weather, prepare for foul.”In the spirit of preparedness, I hope you are preparing to attend the CTI 2019 Annual Conference February 10-14 in New Orleans. New Orleans is not only a favorite destina-tion, but a city that has suffered the ravages of a hurricane and recovered. We extend our sympathies to those who have suffered the devastation of natural disasters through-out the world and hope for less severe weather in the future.

Jeffrey ParhamO/O Program Chair

Larry has a BSME degree from the University of Kansas, a MSME degree from the University of Missouri and is a registered professional engineer.CTI’s 128 Acceptance Test Code provides the methodology to measure sound coming from heat rejection equipment. Concerns have been voiced in the past regarding the sound power calculated for small towers generally used in HVAC applications using the 128 code that it may not properly depict the sound energy observed in the field. This session will present the findings from recent studies that have been performed to evaluate the sound power emitted from various heat rejection equipment configurations comparing the current 128 code small tower method to various alternative techniques such as AHRI, ISO, DIN and EN. The 128 technical committee has voted to adopt a new technique for calculating the sound power based on sound pressure measurements of HVAC sized equipment that ad-dresses inconsistencies of the surface area and measurement locations in this code as well as providing better correlation to globally recognized standards.

Session 5: Corrosion and Steamside Inspection of Air-Cooled Condenserspresented by Andrew Howell, Technical Executive for EPRI’s Materials and Chemistry Program in the Fossil Generation Sector.

Dr. Howell serves as a subject matter expert on research programs and projects associated with power-generating facilities involving water management technology (ad-vanced cooling focus) and steam cycle chemistry, He joined EPRI’s staff in January 2018.Air-cooled condensers (ACCs) are large structures with steamside surfaces typically composed of carbon steel, thus providing the potential for major generation and transport of iron oxide corrosion products. The low-pressure turbine exhaust environment can be cor-rosive for carbon steel, and the high velocities of steam transported through the ACC accelerate the removal of corrosion products generated on carbon steel surfaces,

particularly where turbulent flow exists, such as at heat exchange tube entries. In addition, the thin-walled tubing necessary for enhancing heat transfer to air is a risk for through-wall corrosion, thus introducing the contaminants and performance inefficiencies associated with air inleakage. Optimal steam cycle chemistry treatment, along with condensate filtration, can effectively manage the corrosion and transport of iron, but periodic internal inspection of steamside surface is very useful in confirming the effectiveness of such treatment. A rating scale for steamside corrosion has come into widespread use among ACC operators over the past decade.

Water Treating Panel Monday, February 11, 2019 2:00p - 3:30p

Topic: Best Practices for Water Treatment Program Performance Guidelines - A Long Overdue Update by IndustrySummary:For the past 40-50 years, performance guidelines for water treatment programs have languished under the metrics when dichromate and gaseous chlorine were the norm in HPI/CPI industrial accounts from a chemical treatment perspective.Likewise, HVAC systems were universally not included in any guidelines for water treatment program performance, other than manufacturers general recommendations for water quality for warranty considerations.This panel discussion will address the shortcomings of previous guidelines related to corrosion, scale, and bio growth control and will offer new, updated program performance guidelines as a draft document for WTG-161, which will hope-fully be published after comments from this panel discussion have been addressed.The discussion of the draft document will include panelists from a variety of industries from an “End User” perspective, as well as participants representing major water treatment suppliers to those industries.We are looking for a “spirited “ discussion of the proposed, updated performance guidelines specific to industrial customer

categories. The Water Treatment Program Committee will evaluate and consider all comments, relative to developing a final draft of CTI-WTG-161: Water Treatment Program Performance Best PracticesPlease join the Committee Panel Discussion on Monday, from 2:00-3:20 to offer your comments on these proposed new guidelines.Jack Bland-Best Practices Committee ChairCharles Kuhfeldt-Water Treatment Committee Chair

8:30a - 9:00aTP19-02Reclaim Water for Cooling Tower Makeup; Not as Simple as PerceivedBrad Buecker and Ray Post, ChemTreat, Inc.

Brad Buecker is Senior Technical Publicist with ChemTreat. He has 35 years of experience in or affiliated with the power industry, much of it in steam generation chemistry, water treatment, air quality control, and results engineering positions with City Water, Light & Power (Springfield, Illinois) and Kansas City Power & Light Company’s La Cygne, Kansas station. He also spent two years as acting water/wastewater supervisor at a chemical plant. Most recently he was a technical specialist with Kiewit Engineering Group Inc. He has authored many articles and three books on power plant and water/steam chemistry topics. He is a graduate of Iowa State University.Growing emphasis, and rightly so, is being placed on water recovery and reuse to help sustain our planet’s water supplies. By choice or

mandate, design engineers for many new industrial plants are selecting alternatives to fresh water for plant makeup, with an increasingly common choice being effluent from a publicly owned treatment works (POTW). These waters go by various names including reclaim water, grey water, purple-pipe water, and so forth. Regardless, virtually all reclaim waters contain elevated concentrations of ammonia, nitrate, organics, phosphate, and suspended solids, all of which, if left untreated, can lead to a nightmare scenario of microbiological fouling in cooling towers and cooling systems; a point that is sometimes not emphasized enough to those designing new facilities or switching supplies at existing plants. But with proper pre-treatment and cooling water chemical treatment, these waters can successfully be utilized for cooling water makeup. Methods to prepare this water for use in cooling systems include biological treatment of the makeup, consistent and reliable biocide feed to the recir-culating water, and use of all-polymer treatment for scale/corrosion control in place of the phosphate/phosphonate programs of the past. The latter has also been gaining impetus due to concerns about the environmental impacts of phosphorus discharge to lakes and rivers.

9:00a - 9:30aTP19-04DiscFiltration for Cooling Water TreatmentBill Willersdorf, Veolia Water Technologies

Bill Willersdorf has been serving the water and wastewater industry for over 40 years, primarily in the Power Generation industry. He has a BS in Environmental Engineering from Lehigh University and a MBA in Marketing.He has primarily worked for two corporations; Graver Water and one company that went through several acquisitions and name changes- Per-mutit/USFilter/Siemens Water Technologies and Veolia.Bill is currently Veolia Water Technologies’ Global Power Director and serves on the Executive Committee for the International Water Conference, sponsored by the Engineers Society of Western Pennsylvania.He has spoken at the World Bank in Washington DC during ‘Water Week’ and at other prestigious conferences; including the IWC and the Electric

Utility Chemistry Workshop sponsored by the University of Illinois; and now is happy to add the Cooling Technology Institute’s 2019 annual conference.Global conservation of fresh water via reuse is a passion- as is fresh water fishing! Bill and his wife Carol have three grown children and three Grandchildren- in 3 different States (FL, NJ and TX)Discfiltration is not a new technology but it has only recently caught on for cooling water treatment. Most discfilter installations are at POTW’s for tertiary filtration of sewage and since many industries are using reclaim water for cooling it was a natural progression and a very inexpensive way to filter large quantities of water. They have been applied for cooling water make-up, sidestream filtration and cooling tower blowdown. Major advantages: low installed cost, continuous filtration; low backwash rates and volumes- some clients reducing backwash volume by 90% over media filters.

9:30a - 10:00aTP19-06Impact Of Legionella Regulations On Water Treatment Programs And Control – An Observational Prospective SurveyPatrick Racine, Klenzoid Canada – Eldon WaterPatrick Racine, P.Eng., CEM is General Manager of Klenzoid Canada and Eldon Water.

Dave has used his six-sigma black belt training for Chocolate Bayou Plant (CHB) as well as other sites. Technical Lead for numerous Root Cause Analysis Studies at the CHB site and other Ascend sites involving water chemistry issues.A Review of learning’s for cooling tower system maintenance

focused on practical experience. Topics covered will include the following: Pump Perfor-mance, Pump Screens and Side Stream Filtration, CT PM Maintenance Plan Overview, Transition to FRP from wood, Fan Maintenance and Monitoring, and Counterflow Towers.

9:00a - 9:30aTP19-03Bolted Structural Connections In Fiberglass MaterialsMark Martich, Cyrco, Inc.

Senior Design Engineer and Project Manager with extensive US and international business development experience managing cross-functional teams. Products include high-volume automo-tive and other consumer products, OEM electro-mechanical and solid-state electronic components, industrial controls, telecom-munications network components and network management equipment. Technical expertise includes injection & transfer plastic molding, metal stamping, sheet metal fabrication, tool-ing, offshore sourcing/relocation, and returning production to the US through product redesign and automation. Recognized

for creative contributions to the growth of small and large organizations with more than 25 US utility patents and intellectual property protection experience spanning 25 years while leading and contributing to new product development.This paper compares several methods of connecting fiberglass pultruded plastic (FRP) structural members with bolts that are commonly used in the cooling tower industry. The study shows full-scale test results and compares the results with theoretically pre-dicted values. The geometry of the structural members studied are representative of the diagonal bracing typically found in cooling towers, but the results should not be lim-ited to just those members, or only structures found in cooling towers for that matterr. 9:30a - 10:00aTP19-05A Fouling And Thermal Performance Test Rig For Cooling Tower Fill SelectionJohannes P. Kotze, TF Design and Ockert Augustyn, Eskom Soc Ltd Bio:

Johan Kotzé obtained his PhD from Stellenbosch University in 2014. His research pioneered the use of metallic phase change materials for isothermal energy storage with eutectic molten metals as heat transfer fluids to enable the use of supercriti-cal steam in concentrated solar power (CSP) applications. He went on into CSP research on robust, low cost, self-learning heliostat technology to reduce the cost CSP in the Helio100 project. Currently Johan is working as a project manager and senior engineer at TF Design, a company with expertise in thermo fluids, heat transfer, thermodynamics and mechanical

engineering. ESKOM’s coal fired power stations mostly have natural draft wet cooling towers, where excessive fouling results in maintenance and performance issues. ESKOM is planning to replace the asbestos fill in selected cooling towers and need to evaluate potential replacement fills. A set of four test rigs has been built that simulates conditions within a natural draft wet cooling tower. Water tapped from a cooling tower is used in the test. Both the fouling and thermal performance of the fills are measured as fouling occurs over time. This paper presents the overall design of the test rig, and initial results.

10:00a - 10:30aTP19-07High Efficiency Heat Exchanger For Ice Energy Storage And BeyondMitchell Ishmael, Levon Atoyan, and Grady Iliff, Active Energy Systems

Dr. Ishmael, the inventor of our technology and initial force behind Active Energy Systems, received his Ph.D. in Materials Science and Engineering from Cornell University in May 2017. Dr. Ishmael has experience designing, building and using experimental equip-ment for precision measurements of material properties. He has synthesized phase change materials for efficient and cost effective thermal energy storage.Active Energy Systems has developed a new high-efficiency multi-phase heat exchanger for ice energy storage. We achieve our high performance by constantly shedding the ice from the freezing

surface. Doing so, first we achieve 5-10x larger freezing rates than currently seen. Second, an ice storage system that uses our heat exchanger takes up much less space than what is currently offered, a great benefit for high-density urban environments. Third, the heat ex-changer operates at steady freezing and melting rates, a major improvement to the transient behavior seen in current systems. These factors combine to substantially lower costs and increase applicability of the ice energy system.

10:30a - 11:00aTP19-09Extending The Service-Life of Reinforced Concrete Structures By Means Of Cathodic-ProtectionEyad Alhariri, Structural Technologies

Eyad Alhariri is the NACE CP Specialist & Instructor Director of Corrosion Solutions. Mr. Alhariri has experience in the design, installation, testing, and commissioning of both conventional ca-thodic protection systems as well as cathodic protection for steel in reinforced concrete structures. He is a member of IEEE, SCS, and NACE, and has recently become a NACE instructor for Cathodic Protection Certifications. Reinforced concrete structures are meant to function with little maintenance. As structures age, it’s important to choose a repair approach focused on long-term protection to extend service-life

and reduce maintenance costs. This paper discusses a cooling tower basin that required corrosion protection via an ICCP system. This system showed significant cost savings by eliminating future repairs and led to a second phase implementation on untouched areas of the basin. Data collected since the system’s commissioning confirmed both repair phases are protected. A life-cycle cost analysis illustrated the value of a one-time cost system for long-term corrosion protection.

11:00a - 11:30aTP19-11Cold Water Data Collection Method For An Individual Cell Of A Multicell TowerArushi Shukla and Navneet Kishor Dubey, Brentwood Industries India Pvt Ltd

The speaker has been working for Brentwood Industries India Pvt. Ltd. for three years as an Applications Engineer and has a Bachelor’s of Technology in Chemical Engineering from one of the top Engineering Institutes of India. She is a research enthusiast and has publication in prestigious research journals such as American chemical society (ACS) - Journal of chemical and engineering data, has presented various papers and has participated in significant workshops and exhibitions at her University. She is a permanent resident of Chhattisgarh, India. There are instances when, an owner wants to assess the thermal performance of just an individual cell of a cooling tower as per

ATC 105. But, the cold-water outlet being common for the entire tower, it has been very difficult to devise a method wherein a cell can be isolated from the tower and thermally tested. This paper addresses solution to this problem- encompassing initial ideas, challenges faced and troubleshooting involved in a fill demo test conducted in India as per ATC-105, utilizing a unique, modular and cost-effective test set-up to thermally assess individual cell of the tower.

speaker on the national level on the subject of water treatment and Legionella prevention.Localized Legionella regulations often get implemented following an outbreak. Many questions have been raised regarding the effectiveness of such regulations. Following the Quebec City Legionella outbreak in 2012, the province of Quebec introduced legislation requiring owners of evaporative cooling systems to register their cooling towers. Owners must now document the mechanical maintenance program as well as their water treat-ment program. Since July 2014, they must also sample for Legionella on a 30-day interval basis. What was the impact of the regulation on cooling water treatment programs, con-trol schemes and the industry? Through the review of what is believed to be the world’s largest dataset of over 10,000 Legionella samples and corresponding 10,000 service reports from field engineers, we will draw conclusions and try to answer some of these questions.

10:00a - 10:30aTP19-08Optimized Cooling Water Circuit Brings Cost Savings of More 50%Christophe Vanschepdael, ENGIE Laborelec

Christophe Vanschepdael is a Project Engineer at ENGIE Labor-elec, and an expert in water treatment, including boiler and cool-ing water treatment, working for power plants worldwide. With a bachelor’s degree in Chemistry and the Environment obtained from La Haute Ecole Louvain en Hainaut in 2006, he has participated in seminars and workshops, and has presented a number of papers on water treatment. He received a Grand Prix at the GDF Suez Innovation Awards in 2014 for his work on the implementation of an innovative, cost effective and safer anti-scalant for cooling water circuits.

Cooling water treatment is a major element of total chemical costs in power plants. For new plants, the relevant guidelines are usually somewhat conservative, and treatments are not optimized for the specific cooling circuit. This case study discusses cooling circuit treat-ment optimization carried out by ENGIE Laborelec at a Belgian power plant. The annual cost of the original water treatment was estimated at about 700,000€ per year. Optimiza-tion was achieved in three steps, starting with evaluation of the make-up water, followed by technical optimization via pilot testing and finally implementation on site. In addition, the solution takes into account environmental factors, with the study leading to the annual water treatment costs falling to 325,000€ per year.

10:30a - 11:00aTP19-10Metal And Organic Solutions For Reduced Phosphorous ApplicationsPaul R. Frail and Claudia P. Pierce, Suez Water & Technologies Solutions

Paul R. Frail is currently a Senior Engineer with Suez Water & Technologies Solutions with 7 years’ experience in the Cool-ing division (2010 – Current). Prior to working with Suez he completed a post-doctorate fellowship and PhD degree at the University of Pennsylvania in the Materials Science and Elec-trical Engineering Departments and Chemistry departments respectively. In the Cooling division, he has focused primarily on deposit control and corrosion control. During this time, he has developed expertise understanding the relationship between surface chemistry, corrosion rate, chemical treatments, and wa-

ter characteristics. Paul has authored and co-authored 20 peer reviewed publications, 4 patent applications, and currently belongs to the ACS and NACE. Customers are facing a trending reduction in the allowable phosphorous they can expel from open recirculatory cooling systems in direct discharge applications, requir-ing significant modification of traditional treatment programs. Other Customers have had to circumvent fouling associated with the use of phosphorous inhibitors, seeking non-fouling options and assurances. This paper will provide a review of metal solutions, as well as, highlighting recent advances in the use of aluminum and all organic solu-tions. Surface analysis was used to identify passivation films and correlate their chemical composition to respective treatment and water conditions; providing the knowledge to manipulate film chemistry for performance.

11:00a - 11:30aTP19-12Control of Ozone Based On Water Temperature For Reduction Of Legionella In Cooling TowersDave Gilbert, EMO3 Inc.

The author is a mechanical engineer and owner of EMO3 Inc. Graduated from the Royal Military College of Canada, he has subsequently and successfully created technology companies representing sustainable solutions to societies needs. As such, EMO3 provides sustainable solutions for industrial water treat-ment needs notably for cooling towers.Having worked and studied in water treatment for cooling towers and industrial applications, the author has pioneered a method to control ozone dosage in treating waters in cooling towers in order to control bacteria growth and Legionella development. Ozone

being a very powerful biocide has proven effective in neutralizing Legionella pneumophilia in water. Several factors contribute to bacterial and Legionella growth in cooling towers, one of which is water temperature. Knowing that ozone half-life is reduced by higher water temperatures while bacterial growth increases, the paper will present a method to control ozone dosage to maximize the reduction of bacterial growth while avoiding over-dosing.

Joe Leist is the CEO of Scranton Robotics USA, Inc.On-line tank cleanings utilizing submersible robots and basins have greatly improved the landscape of industrial water tank cleaning by reducing costs and liabilities while greatly increas-ing site safety. This is the next step in tank cleaning, along with new, improved forms of tank inspections.

2:00p - 2:30pTP19-15Deformation Behavior of Cooling Tower FillsNina Woicke, Enexio Water Technologies GmbH

Dr.-Ing. Nina Woicke is the head of R&D for ENEXIO Water Tech-nologies. She is an expert in process engineering and has a PhD in polymer analysis from the University of Stuttgart, Germany. She has nearly 20 years of experience in plastic engineering as well as 10 years of knowledge on the use of structured packings in vari-ous industrial applications like cooling towers. Her main goal is to create products with enhanced properties or performance, to include trendsetting technologies into the production processes and to improve the cost effectiveness of the whole manufacturing chain for the ENEXIO products.

Mechanical behavior of plastic cooling tower fills is not only dependent on the pure load, but also on loading time and temperature. In a previous paper of the author a simplified viscoelastic deformation model had been derived to take these factors into account, but at that time the model was calibrated only for one type and material (PP). Now this model has been extended to generalized to PVC as well as a second product type. To show the model in application, it has been used to calculate the deformation for a specific case in a cooling tower environment.

2:30p - 3:00pTP19-17Life-Cycle Cost Analysis For Concrete Cooling TowersMark Williams, Walter P. Moore And Associates, Inc.

Mark Williams, Ph.D., P.E., S.E., is a Principal and Senior Project Manager in Walter P Moore Diagnostics Group. He has 16 years experience in structural engineering analysis, design and manage-ment, as well as software engineering research and development. Dr. Williams has been involved with the restoration of several cooling towers as well as repair of several bridges and garage projects that have used state of the art carbon fiber reinforced polymers for structural enhancementsThe deterioration of concrete cooling towers and the cost of repair-ing, rehabilitating, or replacing deteriorated tower structures is a

major issue for tower owners and operators. This paper will explore the application of a Life-Cycle Cost Analysis (LCCA) as a useful tool to predict and schedule maintenance and repair tasks for concrete cooling towers. Factors that affect the durability of concrete cooling tower structures, including concrete cover to reinforcement, type of reinforcement, concrete material properties, admixtures, concrete surface treatments, cooling water chemistry, and environmental exposure, will be discussed as input parameters to concrete service life pre-diction models.

TP19-19Utilizing New Technology to Provide Comprehensive Asset Management for Cool-ing Tower MaintenanceGlenn Schaefer, Eric Koehler, and Eyad Alhariri, Structural Technologies

Glenn Schaefer is the Director of Durability Solutions at STRUC-TURAL TECHNOLOGIES and has over 25 years of experience in the industry with a focus on concrete durability. He oversees all condition assessments and investigative efforts, including the management and integration of project disciplines such as forensics, corrosion, testing, and determining service life to develop holistic repair recommendations for a wide variety of concrete structures throughout the world. Glenn has led teams of technical experts in the evaluation and analysis of concrete structures with a focus on concrete durability, concrete materials,

and degradation mechanisms, and serves as technical liaison on these topics to other parts of the organization.Because cooling towers are such massive structures, assessments can be challenging. Typically, only limited and cursory tactile field assessments and sample collection are evaluated to determine areas in need of repair. Utilizing new technology, such as drones, allows for more comprehensive inspections at a reasonable cost. Advancements are tak-ing these technologies past standard assessment methodologies and into 3-D graphic modeling, design, and integrated quality assurance during construction to create an asset management approach for cooling tower infrastructure maintenance. This paper discusses where this new technological approach is taking us in each area of asset management from investigation and analysis, to design and quality control in a BIM-like environment.

Osprey Corporation Ltd & FTL (Fluid Technologies (Env) Ltd) work together in a JV headed up by David Missions (Process Me-chanical Engineer & TD of Osprey) & Howard Davis (Chemical Engineer & MD of FTL). They market a unique fluid bed technol-ogy, which simultaneously absorbs toxic gases, removes very fine particulate & recovers heat to high efficiency in a single compact unit. Employed across a very wide range of industrial applications this versatile technology has recently been adapted to Cooling Tower configuration trialed successfully at Huhtamaki’s Maine pulp & paper plant.

These Cooling Towers use an improved cooling variant of the technology originally de-veloped for gas scrubbing which simultaneously absorbs toxic gases, removes sub-micron particulates and recovers heat by direct gas-liquid heat transfer. Using the vigorous fluid bed tumbling action for ultra-rapid counter-current contact of hot liquids with cooling gases achieves the following advantages: Unrivalled Heat Transfer in Highly Compact Towers, Sub 3ºF Approach & Range Temperatures Achieved, Guaranteed Non-Clogging allows Cooling of Slurries, Minimal Air to Water Ratios Minimize Fan Power, Self-Clean Mobile Packing Overcomes Biofilm Build Up.

7:30a – 8:00aTP19-16The Rest of the Story – Your Cooling System is Being Treated – What Can Go Wrong?Adam Green, Baker Donelson and Robert J Cunningham, International Water Consultants

Adam Green is an attorney and the Chairman of Baker Donelson’s Water Technology and Water Treatment Group. Over the past 17 years, has successfully defended high value, catastrophic failures of building water systems on a national scale. He has served as lead counsel in litigation arising from failures of varying degrees and from a myriad of different causes. In addition to defending multimillion dollar property damage claims, he has successfully defended and advised clients on a wide range of matters relating to water borne pathogens, water handling systems and water treat-ment throughout the United States and in international venues. He

has published numerous technical papers on the subject and is a regular speaker with the Association of Water Technologies and the Cooling Technology Institute where he serves on various technical committees.Open and closed cooling systems are subject to the very real constant threat of corrosion, scale, and microbiological fouling. While water treatment is the science of minimizing these conditions, water treatment alone cannot avail the system. The process by which systems are designed, installed and started-up is complex and necessarily involves various specialized trades. In order to provide for optimum conditions, these trades must closely coordinate for a system that remains uncompromised from initial conception through hydro-testing, commissioning and turnover. This publication will address the critical moments in the life of a cooling system, areas of common risk and how those risks can be minimized.

8:00a - 8:30aTP19-18Legionella Law: How Did We Get Here?Adam Green, Baker Donelson and Robert J Cunningham, International Water Consultants

Adam Green is an attorney and the Chairman of Baker Donelson’s Water Technology and Water Treatment Group. Over the past 17 years, has successfully defended high value, catastrophic failures of building water systems on a national scale. He has served as lead counsel in litigation arising from failures of varying degrees and from a myriad of different causes. In addition to defending multimillion dollar property damage claims, he has successfully defended and advised clients on a wide range of matters relating to water borne pathogens, water handling systems and water treat-ment throughout the United States and in international venues. He has published numerous technical papers on the subject and is a

regular speaker with the Association of Water Technologies and the Cooling Technology Institute where he serves on various technical committees.Whether due to a true increase in disease frequency or improved diagnostics, reported cases of Legionnaires’ disease are on the rise. The flurry of corresponding litigation has been substantial. Understanding the critical factors that influence judicial decisions in Legionella lawsuits is paramount in understanding and managing risk. This publication will review the roadmap of landmark decisions and the current state of Legionella law. The potential issue of competing standards is imminent. These standards may complicate and could delay codification of best practices.

8:30a - 9:00aTP19-20Tailoring Scale Prediction Models to a Specific Application: Cooling WaterRobert J. Ferguson, French Creek Software, Inc.

Rob Ferguson began modelling the minimum effective dosage for scale inhibitors in the early 1970’s and has been a major contributor to the practical application of computer modelling to water treatment applications, control, and treatment. He worked in research. marketing, computer services and technical support for several major water treatment service companies prior to cofound-ing French Creek Software in 1989. Mr. Ferguson was honored to receive the Association of Water Technologies Ray Baum Water Technologist of the Year Award in 2017. Rob was educated at the U.S. Naval Academy and the University of Minnesota where he

received a BS BioCh in 1971.This paper discusses the practical application of advanced physical chemistry techniques commonly employed in cooling water, geothermal and oil field chemistry, to application specific modelling of mineral scale formation and control in cooling water systems. The techniques are discussed and applied to: Predicting scale formation; Identifying the upper driving force limit for inhibitors and blends; Developing inhibitor models for minimum effective dosage; and Developing models for preventing failure due to inhibitor solubility. The methods discussed have been validated in field applications.

9:00a - 9:30aTP19-22Using Experience And Six Sigma To Optimize Water TreatmentDavid W. Anton, Ascend Performance Materials and John Morstead, Suez Water Technologies

Dave has supported many site engineering teams as an energy and water treatment expert. He has developed numerous tools for tracking energy and chemical performance. Many sites have used his leak calculator tool for steam, water, compressed gases, and insulation to determine the potential impact of system energy losses. Dave has used his six sigma black belt training for Choco-late Bayou Plant (CHB) as well as other sites. Technical Lead for numerous Root Cause Analysis Studies at the CHB site and other Ascend sites involving water chemistry issuesA review of learning’s for cooling tower system treatment program

Topics covered will include the fol-lowing: Passivation of equipment, Stabilization of incoming water quality, Feed locations and measurement analysis, Statistical regression of data, Time lag of processes, Corrators, Coupons, and inspections linking the processes and Drawing straight lines and challeng-ing your sampling process.

9:30a - 10:00aTP19-24Clean And Green Approach To Cooling Tower Water ManagementBee Keong Ng, Innovative Polymers P/L

Chemical & Material Engineer- Graduated 1980 University Of Auckland, New Zealand Co-Inventor of a “Chemical Free Water Treatment System for Cooling Tower”Scale deposition is a challenge commonly encountered when pro-cessing aqueous solutions containing ions of sparingly soluble salts. Scale deposits can readily form on flow surfaces when a solution is concentrated beyond the solubility limit of a dissolved sparingly soluble salt or when a solution containing an inverse solubility salt is in contact with a hot surface. Many brackish water sources contain alkaline forming ions which tend to precipitate CaCO3

and Mg(OH)2. Controlling the scaling potential of water circulating in cooling towers using precipitation by electrolytic methods has long been recognized. But now, it can be enhanced with a modern control system and chemical-free approach.

8:00a - 8:30aTP19-23ATC-105 And Cold End System PerformanceUpendranath Bhupal, Spectrum Consultants Pvt. Ltd

Upendranath Bhupal is a Mechanical Engineer with an overall experi-ence of 27 years. He has spent his initial years of work in a thermal power plant and the subsequent years of his experience dedicated to cooling towers. He has worked with Balcke Durr, India for 9 years and is presently a consultant to the cooling tower industry.A cold end system in a thermal power plant comprises of a condenser and a cooling tower. The performance of each of these equipment is inter-dependent, which means that a below par performance of one affects the other. This aspect of inter-dependence of performance of these equipment is often ignored when it comes to PG testing of cooling towers and only the condition of the cooling towers is as-

sessed for its readiness for a PG test while that of the condenser is ignored. There are many situ-ations where the condition and performance of the condenser directly affects the performance of the cooling tower. Such situations, based on experience gained during third party PG tests in India, have been explained briefly in the paper so that agencies party to PG tests can take an informed decision vis a vis the test conditions of the cold end system as a whole.

8:30a - 9:00aTP19-25Adiabatic Fluid Coolers and Condensers: Impact Of Pad System Design On Saturation Efficiency And Unit OperationJennifer Hamilton, Evapco, Inc.

Jennifer Hamilton is the Vice President of HVAC Product Develop-ment at Evapco, Inc where she manages the design, testing, and rat-ing of factory assembled cooling towers and closed-circuit coolers. She has been a part of the cooling tower industry since 2005 with experience in both Applications Engineering and Product Develop-ment. Jennifer holds a BS in Chemical Engineering and a Minor in Environmental Engineering from the Pennsylvania State University. Prior to joining Evapco she spent several years as a consultant to the Environmental Protection Agency (EPA) where she supported the Office of Water, the Confidential Business Information group and the Office of Compliance.

Air-cooled, closed circuit coolers and condensers are growing in popularity due to increasing water costs, water scarcity, regulatory burdens, and the desire to reduce maintenance associ-ated with water-cooled products. However, in some climates, applying air-cooled, dry heat exchangers can be cost prohibitive due to capital, available installation footprint and total system energy requirements. Incorporating an air dry-bulb pre-cooling system via adiabatic pads to an air-cooled heat exchanger can be a solution to better balance costs and resource consumption. Consumers face a major challenge when evaluating this technology: widespread commercializa-tion and variation in claimed adiabatic saturation efficiency exists in the global marketplace. This variation results in a dramatic impact to the size of the air-cooled closed-circuit cooler or condenser. Currently, no third-party performance verification or certification program exists for adiabatic coolers, adiabatic condensers or the adiabatic pads. While adiabatic cooling is a known process, thoroughly understanding how it works is critical to ensure the air-cooled heat exchanger is properly designed to meet thermal performance and energy use expectations.

9:00a - 9:30aTP19-27A New Technology For Ultra-Low Noise And High Efficient Axial Fan For Industrial ApplicationRiccardo Provasi, Axial Fans Int Srl

Riccardo Provasi current position is Director of Global Technology and Innovation with Axial Fans International. His fields of expertise are structural analysis, thermodynamics, fluid dynamics, acoustics and signal processing. Before joining Axial Fans International, Ric-cardo held the position of Director of Process Engineering and R&D Department with SPIG S.p.A., where he provided technical supports in wet and dry cooling system design area and directed the develop-ment of new products. Formerly, Riccardo was the Technical Direc-tor of Cofimco S.p.A., a leader in aluminum and fiberglass axial fans manufacturing. Riccardo received the M.S. degree in aeronautical engineering from the Politecnico of Milan, Italy, in 1989.

In the industrial plants, the regulations concerning the noise emission are prescribing more and more stringent requirements. In the large cooling systems like cooling towers and air-cooled steam condensers, to comply with these regulations, the use of the so called ultra- low noise fans is mandatory. But these fans actually available on the market, despite their optimal acoustic properties, have some negative aspects in terms of efficiency, weight, and size, that they determine a huge impact on the cost of the whole unit. This paper describes an innovative technology solving all the negative aspects that also the last generation of the ultra-low noise fans could not solve completely.

9:30a - 10:00aTP19-29CTProfiler: Performance Evaluation of Cooling TowersJure Smrekar, JS Energy Ltd and Marko Hocevar, University of Ljubljana

Jure Smrekar is Engineering Director at company JS energy Ltd. His doctorate work was in performance evaluation of local anomalies inside natural-draft wet cooling towers. He manages projects related to continuous improvements of fossil-fired power plants. His expertise is in performance improvements of boilers, turbines and cooling sys-tems with numerous applications in industry. Dr. Smrekar was also a project leader of the EU innovation project CTProfiler: Performance Evaluation of Cooling Towers. In the natural-draft cooling tower (NDCT) market, there is no service that can estimate the impact of local issues inside NDCTs on power production, financial losses and emissions. Due to the slow pace of

degradation of NDCTs, their big sizes and complexity of heat and mass transfer processes, NDTCs performance degradation is in most cases unnoticed and unattended. In this paper, the solution CTProfiler is presented consisting of: (1) high-resolution mobile-based measuring system for detection of component issues inside NDCT, (2) NDCT and power plant modelling and (3) cost-benefit analyses. Based on the high-resolution measurements, an impact of NDCT degradation, damages or design issues on power generation, financials and emissions is evaluated.

Standing Committee Minutes from July 2018Performance and Technology

Kent Martens - SPX Cooling Technologies, ChairChris Lazenby - Southern Company, Vice Chair

Jared Medlen - Mesa Associates, Vice Chair

1. General Notes a. Discussed setting up a Technical Review Committee to monitor five year document

cycle, review documents that are due for review and report their recommendations to the P&T Committee. This was past practice, but in recent years, the Chair and Vice Chairs have solicited volunteers to perform that function. We will recruit committee members before the next meeting.

b. Some task groups have lost vice chairs. Chairs for these task groups were asked to suggest names for filling vice-chair positions.

c. ATC-107 (test code for air cooled condensers) is due for review. No session was held at this meeting. Virtually all ACC tests are currently performed with ASME 30.1. For the code to be viable, it will need, at a minimum, refreshing; and potentially could “leap frog” the ASME code. This will take a large amount of effort, but has fallen to the bottom of our priority list due to the current load of documents in the cycle that are more in demand. This could be an opportunity to engage members of the ACC Users Group. Further discussion will be required to be able to recommend future action.

d. ATC-105S Test Code for Closed Circuit Coolers. This document is due for review.This group did not meet. Lessons learned from the 105-DS review will be applied, including sections on barometric pressure correction, and the inclusion of performance curves for varying glycol concentration. Hussnain Yaser has asked for members to review and comment in preparation for a teleconference in advance of the Winter Meeting.

2. Task Group Highlights a. STD-202 Publication of Custom Tower Performance Test Results -

Paul Lindahl, Chairi. Discussed administrative details and communication with CPA to be sure document and time table are understood.ii. Participating Manufacturers need to let Paul know if they have not received the CPA report by January 15th of each year.iii. Made editorial change to allow action for extraordinary circumstances.

b. PFM-143Airflow Testing – Sander Venema i. Completed review of instrumentation accuracy/uncertainty sections.ii. Removed pressure recovery of cylinders out of the main document and moved to an appendix. Table to be revised.iii. Measurement uncertainty review pendingiv. Goal of final draft before Winter Meeting.

c. ATC-105DS – “Dry Supplement” to test code for dry cooling performance of fluid coolers – Jennifer Hamilton, Chair

i. Expedient handling is necessary to support ASHRAE 90.1 2019 modifications that will include establishing minimum efficiency standards for dry performance.ii. Reviewed and incorporated or responded to ad-hoc comments. Ad-hoc reviewers were sent the comments overnight. All three have responded and approved all comments. The document is ready for a board vote.

d. ATC-105 Acceptance Test Code for Cooling Towers – Larry Burdick, Chair i. Reviewed ad-hoc comments on Appendices Q&R (Helper Tower appendix for IP and SI units). Both were approved. ii. Reviewed Appendix N (Line Loss Calculations); discussion held. Equations and procedure draft will be distributed to the group by mid- August; expect approval and ad-hoc review to be complete by September 30th. iii. All other sections have been approved. The document should be ready to send to the CTI office for formatting and draft printing by September 30th.

e. ATC-140 Isokinetic Drift Measurement Test Code for Water Cooling Tower – Chris Lazenby, Chair

i. Ray Post recruited two surfactant experts from Dow (Kaylie Young & Wanglin Yu) to discuss the impact of surfactants on surface tension. Excellent feedback on session, and much was learned. Dow will be providing some surfactants for preliminary testing purposes two members. R&D proposal scope may be impacted by this preliminary testing, which is expected to be complete in time for a November teleconference. ii. Discussion on potentially adding conductivity method to analyze drift rates as a secondary (non-preferred) method; delegated to a subgroup to review Vincent Ganzitti language to be reviewed prior to the November teleconference.

f. ATC-128 Sound Test Code – Larry Burdick, Chair i. Reviewed comparative test results of 128 versus methods in other codes, expanding on JP Libert’s paper TP-18-27. Compared to ISO3744 (hemispheric), good alignment was found for cube-shaped towers; more variability (2-3 dBA in Sound Power Level) in long towers and long dry coolers. Group members were asked to develop ideas of how to deal with discrepancies in long aspect ratio towers. ii. Will reach out to sound consultant for availability for review. iii. Teleconference is planned for the week of August 6th to discuss further.

San Antonio summer meeting. The task group is focused on constructing a new document discussing water generated off site for reuse in cooling water systems. We want operators to know the potential impact on the system from use of water of varying quality. WTG 158, Physical Water Treatment, Mark Winter (Chair). Document is cur-rently at Ad HocWTG 125, Instrumentation and Control, Mike Dorsey (Chair) – complete and approved by boardWTG 142, Galvanized/White Rust John Zibrida (Chair), Dwight Emerich (Vice-Chair).Currently the task group has nine members. John will be sending out the current white rust document along with the AWT white rust document to the subcommittee. SPX and Evapco were mentioned as possible contributors. Work will continue at the summer meeting. A literature search on the subject only revealed patents on new galvanized corrosion inhibitors. We don’t anticipate the need for substantial changes to the current document.GDL 159, Legionella, Bill Pearson (Chair)/Helen Cerra (Past Chair).The document is going through final editing. Looking at going to Ad Hoc later this year.

New Business: We hope to have, and are working towards a panel discussion about the WTG 161, Best Practices Guidelines for Cooling Water Systems at the 2019 winter meeting. It is anticipated that this will be a draft version of the document which will then be reviewed by the panel and opinions about the limits and concept input will be heard from the audience. After work on the non-oxidizing biocides document, WTG 126, Application of Non-Oxidizing Biocides, is completed (likely to be complete in the summer of 2018), we discussed developing a similar document in the same format for newer oxidizing biocides. There is an existing document for oxidizing biocides, WTG 141, which was reviewed in 2016 and is listed for sale. However, that document does not address new developments in oxidizing biocides which have come into use. We want to start on this document at the summer meeting.

Old Business:Three documents are in the Ad Hoc review stage, and they are past the stage for receiving the reviews. The plan is to locate and/or have the reviews from the exist-ing reviewers completed or to add new Ad Hoc reviewers. The target is to have these reviews by the summer meeting, which is important, so the documents can be completed.

As stated in its opening paragraph, CTI Standard 201... "sets forth a program whereby the Cooling Technology Institute will certify that all models of a line of water cooling towers offered for sale by a specific Manufacturer will perform thermally in accordance with the Manufacturer's published ratings..." By the purchase of a "certified" model, the User has assurance that the tower will perform as specified, provided that its circulating water is no more than acceptably contaminated-and that its air supply is ample and unobstructed. Either that model, or one of its close design family members, will have been thoroughly tested by the single CTI-licensed testing agency for Certification and found to perform as clained by the Manufacturer.CTI Certification under STD-201 is limited to thermal operating conditions with entering wet bulb temperatures between 12.8oC and 32.2oC (55oF to 90oF), a maximum process fluid temperature of 51.7oC (125oF), a cooling range of 2.2oC (4oF) or greater, and a cooling approach of 2.8oC (5oF) or

greater. The manufacturer may set more restrictive limits if desired or publish less restrictive limits if the CTI limits are clearly defined and noted int he publication.Those Manufacturers who have not yet chosen to certify their product lines are invited to do so at the earliest opportunity. You can contact Virginia A. Manser, Cooling Technology Institute at 281.583.4087, or vmanser.cti.org or PO Box 681807, Houston, TX 77268 for further information.

Cooling Technology Institute Licensed Testing Agencies

For nearly thirty years, the Cooling Technology Institute has provided a truly independent, third party, thermal performance testing service to the cooling tower industry. In 1995, the CTI also began providing an independent, third party, drift performance testing service as well. Both these services are administered through the CTI Multi-Agency Tower Perfor-mance Test Program and provide comparisons of the actual operating performance of a specific tower installation to the design performance. By providing such information on a specific tower installation, the CTI Multi-Agency Testing Program stands in contrast to the CTI Cooling Tower Certification Program which certifies all models of a specific manufac-turer's line of cooling towers perform in accordance with their published thermal ratings.To be licensed as a CTI Cooling Tower Performance Test Agency, the agency must pass a rigorous screening process and demonstrate a high level of technical expertise. Addition-ally, it must have a sufficient number of test instruments, all meeting rigid requirements for accuracy and calibration.Once licensed, the Test Agencies for both thermal and drift testing must operate in full compliance with the provisions of the CTI License Agreements and Testing Manuals which were developed by a panel of testing experts specifically for this program. Included in these requirements are strict guidelines regarding conflict of interest to insure CTI Tests are conducted in a fair, unbiased manner.Cooling tower owners and manufacturers are strongly encouraged to utilize the services of the licensed CTI Cooling Tower Performance Test Agencies. The currently licensed agencies are listed below.

* Type A license is for the use of mercury in glass thermometers typically used for smaller towers.* Type B license is for the use of remote data acquisition devices which can accommodate multiple measure-

ment locations required by larger towers.

Cooling towers are used extensively wherever water is used as a cooling medium or process fluid, rang-ing from HVAC to a natural draft cooling tower on a power plant. Sound emanating from a cooling tower is a factor in the surrounding environment and limits on those sound levels, and quality, are frequently specified and dictated in project specifi-cations. The project specifications are expected to conform to local building codes or safety standards.

Consequently, it may be in the interest of the cooling tower purchaser to contract for field sound testing per CTI ATC-128 in order to insure compliance with specification require-ments associated with cooling tower sound.
