I hope that everyone had a great summer. For most of the US, winter has come upon us early this season! Speaking of summer, one of my highlights was participating in the very successful Summer Committee Workshop in Steamboat Springs, Colorado. A lot of committee work was accomplished and all that attended had a very enjoyable time in the beautiful Colorado countryside. I want to express

my appreciation to members of the Board of Directors, Standing Committee and Task

Group Chairs for their efforts in organizing the many meetings that resulted in good progress on reviewing, editing and authoring numerous documents important to our industry. Congratulations to Vicky, Donna and Andrew for their preparations and efforts that resulted in a very productive and enjoyable Workshop for the attendees as well as their families and guests that came along. I look forward to the upcoming CTI ‘2015 Annual Conference with great expectations. The conference will be held February 9-11, 2015 in New Orleans, at the Sheraton on Canal Street, right across from the French Quarter.

Water Treating Panel DiscussionMonday, February 9, 2015 from 2:00p - 3:30p

The purpose of a cooling water treatment program is to minimize corrosion, deposition, and microbiological growth in the cooling water contracted equipment, and in doing so, to avoid reductions in the thermal efficiency of the equipment and the equipment life and to eliminate health hazards to personnel working near these systems. The accurate control of cooling water treatment programs has become increasingly important and has led to the development of automatic chemical feed, monitoring and control systems, which better protect the cooling water equipment, extend the numbers of years between major turnarounds, and can reduce manpower requirements.

For nearly thirty years, the cooling Technology insti-tute has provided a truly independent, third party, thermal performance testing service to the cool-ing tower industry. in 1995, the cTi also began provid-ing an independent, third party, drift performance testing service as well. both these services are administered through

the cTi multi-agency Tower Performance 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 manufacturer’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. ad-ditionally, it must have a sufficient number of test instruments, all meeting rigid require-ments for accuracy and calibration.once licensed, the Test agencies for both thermal and drift testing must operate in full

9:00a - 9:30aTP15-04 The Impact Of Ionic Strength Upon Inhibitor Speciation and EfficacyRobert J Ferguson, French Creek Software, Inc.

Rob Ferguson began modeling mineral scale formation and its con-trol in 1974 and continues to be a major contributor to the practical application of physical chemistry to identifying and solving indus-trial water treatment challenges. Major career accomplishments include: developing the first successful ultra-low dosage treatment approaches for scale control in high volume utility once through cooling systems (1974); designing and implementing the first real-time microprocessor controlled scale inhibitor controller (1984); making advanced physical chemistry and laboratory study results to water treatment professionals through software available in a user friendly, visual format; and developing a user friendly system

for evaluating scale formation and control under extreme conditions. Rob was educated at the US Naval Academy and University of Minnesota and received a BS in Biochemistry and Microbiology in 1971. Rob worked in research, marketing, and software development for several major water treatment service companies prior to cofounding French Creek Software in 1989,Dosage optimization requires sounds mathematical models for inhibitor dosages. Frequent questions include: What test methods should be used to develop scale inhibitor performance data? How do you determine “end points” where scale inhibition is lost? What experimental design matrix should be used to prepare test conditions? How are failure points determined? This paper addresses these questions and describes recommended test methods for evaluating scale inhibitor performance based upon induction time extension.

8:30a - 9:00aTP15-01 Numerical Study on Erosion at the Tube Entry Region of an Air Cooled CondenserDonghyouck Han, Dept of Mechanical Engineering, Korea University

Dr. Han holds a Ph.D. and is specifically interested in heat transfer enhancement. He has conducted various research projects including test, design, and simulations in thermal systems. He has developed several thermal performance prediction models, especially for multi-phase flow. He is also keen on the thermal system optimiza-tion using computational fluid dynamics and statistical analysis.One of the common issues of an air-cooled condenser is the leakage that occurs at heat exchanger tube entry. Leakage creates prob-lems that not only include power generation loss but also freezing damage of heat exchanger tubes. Through a parametric numerical study with the help of computational fluid dynamics, the effect of

steam velocity, particle diameter, and particle material on the erosion rate are investigated. Additionally, a design guideline to minimize the erosion at the tube entry are presented.

David A. Corelli holds a Bachelor of Science degree in Systems Engineering from Wright State University and a Master of Science degree in Mechanical Engineering from The University of Alabama. He has over 38 years of experience in vibration analysis, instru-mentation, and sensors. He has worked as a test engineer for the Air Force Avionics Laboratory; as a Field Engineer for Hewlett Packard, Entek Scientific, and IRD Mechanalysis; and is currently the Director of Application Engineering for PCB Piezotronics. Mr. Corelli is a Category IV Vibration Analyst in accordance with ISO 18436-2 and is the President of the Vibration Institute.Predictive Maintenance (PdM) can be a key ingredient in suc-

cessful implementation of an effective Asset Management program. Not only can it help manage machinery assets but also can result in significant saving in machine repair costs and lost production due to catastrophic failure and unplanned downtime. However, many companies are reluctant to invest money and personnel in PdM programs because they don’t understand how they work, how much they cost to start and maintain, and especially how to get started. This paper addresses these questions, provides cost justifications, and includes training recommendations and information on the validation of personnel skills through certification of persons per ISO Standards.

Since 1999, Dr. Maulbetsch has been a private consultant to gov-ernment and industry. Most of his work has been on water use and conservation in electric power production. He has published two major studies on alternative cooling systems for power plants for the California Energy Commission and the Electric Power Research Institute. Other studies have included the costs of retrofitting once-through cooled plants with closed-cycle cooling; the assessment of water conservation options for plants in arid regions; the effect of wind on air-cooled condenser performance; and the use of spray enhancement to augment the performance of air-cooled condensers on hot days. Prior to establishing his consulting practice, he was at

the Electric Power Research Institute for 23 years. Before joining EPRI, Dr. Maulbetsch was the Director of the Energy Technology Center of Dynatech Corporation in Cambridge, Massachusetts and before that on the faculty of the Massachusetts Institute of Technology. Dr. Maulbetsch received his S.B., S.M. and Ph.D. degrees from M.I.T. in 1960, 1962 and 1965 respectively.This study develops general guidelines for the arraignment of wind screens and estimates of their effectiveness through a combined program including field testing of a full-scale utility ACC coupled with physical (wind tunnel) and computational (CFD) modeling of the field conditions. Continuous field measurements of ACC and plant performance, ambient conditions, and air velocity and temperature around and under the ACC are being made for a one-year period. The wind tunnel and CFD results will be calibrated and validated with the field data. The models will then be used to explore other situations in an attempt to provide general guidelines for wind screen design and arrangement.

10:30a - 11:00aTP15-09 Cooling Tower Support Framing Systems: Distress and RepairNarendra Gosain and Ray Drexler, Walter P Moore And Associates, Inc.

Dr. Gosain’s focus is now on serving as a technical consultant for complex structural rehabilitation challenges and forensics related work. Narendra Gosain got his Master of Engineering degree in 1965 from Indian Institute of Technology, Roorkee, India and his Ph.D. in Civil Engineering in 1973 from Rice University. He is a licensed professional engineer in Texas.Other than specifying the loads and support points for the cooling towers, the cooling tower manufacturer has very limited involvement in the design of support framing for commercial type cooling towers. Over a period of time, the cooling towers themselves generally undergo the required maintenance, but their support framing is often neglected. As such, extensive deterioration and distress has been observed in several cooling tower support structures. The paper describes some of the problems caused by such neglect and the methods used to restore the integrity of such framing. Some case histories are also discussed.

a B. Eng., Mechanical Engineering from the University of Sherbrooke and is a licensed engineer in the province of Quebec. lt has been well documented that particles smaller than 5 microns in cooling water present the greatest risk of deposit and fouling in cooling tower fill media and condensers. For over 25 years the Vortisand filter has been proven as the most effective means of remov-ing particles down to submicron levels in side-stream filtration applications for HVAC and commercial grade cooling towers. Following an extensive R&D program a series of high-flow filters which are the newest innovation in cross-flow micros and filtration will be discussed in this paper showing how the new design, has resulted in higher flow capacity as required by utility grade power generation projects, providing the benefits to larger cooling towers and for plants looking to achieve Zero Liquid Discharge (ZLD).

Dr. Janet E. Stout is the director of Special Pathogens Laboratory, and research associate professor at the University of Pittsburgh Swanson School of Engineering in the Department of Civil and Environmental Engineering. A clinical and environmental micro-biologist, Dr. Stout is internationally recognized for more than 30 years of pioneering research in Legionella. Her expertise includes prevention and control strategies for Legionnaires’ disease. Toward that end, she has evaluated all major Legionella disinfection tech-nologies in use today, and continues to explore new approaches for Legionella detection and control. Dr. Stout’s research is widely published in major medical and scientific peer-reviewed publica-

tions, and she co-authors Legionella chapters in books and manuals, such as APIC Text, Hospital Epidemiology and Infection Control and the Manual of Clinical Microbiology. An advocate for prevention, she serves on the Legionella guideline committee for the Cooling Technology Institute and on ASHRAE committees: Legionella Guideline 12 and the proposed Legionella standard.Microbiological growth in cooling water systems presents several challenges for water treat-ment providers. Culture methods such as heterotrophic plate count (HPC) and “dipslides” provide valuable information related to general microbiological water quality but require several days to produce results. Alternative methods using adenosine triphosphate (ATP) measurement provide faster results and have been applied when rapid water quality as-sessment is necessary. Our evaluation reviewed potential applications for ATP analysis in cooling water systems. We also assessed whether total bacteria measurement using culture methods or ATP analysis can predict the Legionella presence/absence using both experimental data and data collected from field observations.

TP15-16 An Alternative Approach to Disinfection Using Chlorine DioxideIngmar Hermans and Vincent Van Camp, TwinOxide International B.V.

Ingmar has worked as Manager at Kodak’s Graphics- and Digital divisions for the Europe, Africa and Middle-East Region. He has over 15 years of business experience covering Sales & Service strategy, tactics & operations. Ingmar has held management posi-tions for companies in capital equipment manufacturing, services & consumables sales throughout Europe. One of his current main focus areas is to streamline & optimize the Lead-To-Cash cycle time with positive cash inflow & improved Return On Marketing Investment (ROMI) as a result. Ingmar is focusing today within TwinOxide on developing the ‘two-powder component’ solid chemi-cal Chlorine Dioxide product range to distribute TwinOxide together

with qualified channel partners worldwide. Ingmar holds a degree in Law, has studied Economics and completed his MBA in Antwerp (Belgium).”The use of oxidizing biocides is among the most cost effective means of disinfecting water. Chlorine dioxide has various benefits compared to other oxidizing biocides, but its stability, properties, and characteristics necessitate that in situ generation, typically using precur-sor solutions in a chlorine dioxide generator is a common practice. Apart from chlorine dioxide gas or vapor, the precursor solutions can pose a potential health and safety hazard and require appropriate safety precautions to be incorporated in the design and operation of generation and dosing equipment. The use of solid precursors can simplify the genera-tion of chlorine dioxide, eliminate some of the potential hazards encountered with other generation methods, and produce stable chlorine dioxide solutions which can be used in many types of disinfection applications. Attributes of chlorine dioxide, its generation, and application are discussed in this paper.

TP15-21 Study on the Combustion of Polymers within Cooling TowersChris Bowman and Jia Shen, Brentwood Industries

Chris has been working in the cooling tower industry since 2008. He is a graduate of Villanova University and holds his Bachelor’s degree in Mechanical Engineering. Chris’ experience involves working as a New System Sales Engineer for Trane Company fol-lowed by working as a technical consultant and owner of Bowman Thermal Equipment LLC. Chris’ current position is with Brentwood Industries as the Business Development Manager for North America in their Cooling Tower Division. Polymers used in cooling towers are available in varying degrees of flammability risk, which, historical standards such as ASTM E84 may not accurately represent fully. This paper will discuss the

science behind the inherent burning characteristics of different polymers, including how they burn and how flame retardants work to minimize the burning characteristics, as well as the ignition characteristics with respect to cooling towers in real world scenarios outside of a laboratory. There are many flammability standards used worldwide which will be reviewed as part of the scope of this paper. Cooling tower component manufacturers are using increasingly varied formulations of polymers in the manufacture of their products so it is prudent to analyze if current testing standards provide the complete picture of a cooling tower’s susceptibility to initiating and propagating a fire event. By this analysis the attempt can be made to more thoroughly address deficiencies in engineering specifications that may not tell the whole story regarding the magnitude of risk associated with utilizing certain polymer formulations within cooling towers.

This includes the development of monitoring tools, the diagnosis of thermal losses and the improvement of the performance of cooling towers.

Worldwide, the air moisture content entering a cooling tower may be measured either with a relative humidity sensor, a psychrometer, or a capacity hygrometer. Some European standards, dedicated to cooling tower thermal tests such as EN 14705, historically recom-mend hygrometers for cooling tower acceptance tests for more than 20 years now, while the CTI-ATC 105 (and also 140 ; 150) standard only recommends the use of mechanically-aspired psychrometers. The goal of this paper is to compare the measurement results of these two technologies with CTI-approved psychrometers and commonly used hygrometers for cooling tower tests.

9:00a - 9:30aTP15-24 New Cooling Tower Nozzle - Low FlowDr. Andreas Streng, CTS Cooling Tower Solutions GmbH

Dr. Streng serves as Head of CTS Cooling Tower Solutions GmbH, Dusseldorf/Germany found in November 2006. He has published two papers fo CTI conferences and has several patents. Hes has been a consultant engineer in the cooling tower industry; helping with selection and design of cooling tower comonents and materials; solving specific problems like plume and noise emission; redesign of existing cooling towes to imrove overall performance and total performance tests before and after reconstruction. Dr. Streng did his studies at the Technical University of Dresden, subject process engineering: German graduation: “Diplom-Engineer” (equivalent to graduate engineer) and did his Doctoral thesis at the Technical

University of Braunschweig, subject: thermodynamics of closed evaporative cooling tow-ers, German graduation: “Doctor-Engineer” (equivalent to Ph.D.).This paper is based on a previous one from 2010 where a new full cone cooling tower nozzle of a much better distribution quality was described. An additional spray nozzle will be presented here to extend the working range of full cone nozzles. The main target of these R&D efforts was and is the improvement of the evenness of water distribution in cooling towers and consequentially the overall cooling performance. The paper discusses the development and the results.

9:30a - 10:00aTP15-25 Leveling the Playing Field for Axial Impeller Comparisons and Regulatory ComplianceSham Morten Gabr, Multi-Wing

Hesham Morten Gabr (Sham) is Multi-Wing Group´s Chief Strategy Officer responsible for market intelligence, strategy and planning. Sham leads Multi-Wing´s activities with fan efficiency worldwide and is the Danish delegate and expert on fan in ISO/TC 117 & CEN/TC 156. He is also included in the committee developing draft AMCA Standard 207 (Wire-to-air). In addition to working for Multi-Wing Sham has worked as a strategy consultant, business policy developer and holds a PhD in Business Administration.Axial Impellers are integrated as driven impellers in multiple non-fan products, including cooling towers. However, there is no common rating standard for axial impellers. That means that a level

playing field for axial impeller performance comparisons is absent. No commonly accepted standard for comparing axial impeller data on an apple-to-apple basis exists. There is no commonly accepted guide for compliance officers to follow to support the implementation of regulatory minimum efficiency requirements. Perhaps therefore, some traditional fan manufacturers lobby for having axial impellers integrated into cooling towers tested as complete assembled fans. That means with the specific fan housing geometry section of the cooling tower! In those cases where the cooling tower section and impeller is too big for testing it’s suggested to test a scaled down replica or do in situ testing. To avoid that “not very meaningful” situation and to help create an even playing field, an initiative is pursued to ensure the development of a standard set of fan parameters to be set for testing of axial impellers. This may then be accepted by regulators in lieu of fan performance compliance verification, when the testing of the fan is impractical, represents an undue burden to the customer and may be technically unjustifiable.

Since 1985, he has been an active member of the Cooling Technology Institute (CTI) where he has chaired and co-chaired technical committees

8:30a - 9:00aTP15-18 Alternative to Bromine Improves Cooling Water Microbial Control and Overall TreatmentAndrew Boal, MIOX Corporation

Dr. Boal received his Bachelors and Masters degrees in Chemistry from North Carolina State University and his doctorate in Chemistry from the University of Massachusetts, Amherst. After graduating, he worked for Sandia National Laboratory and was a Fellow at a NASA Research Institute at the University of Hawaii before joining MIOX Corporation in 2006. At MIOX, Dr. Boal applies his R&D background to the development of innovative disinfection and water treatment technologies based on MIOX’s core expertise in electro-lytic production of disinfectants. Ammonia in the cooling loop poses an additional challenge for Hy-pochlorite or oxidizing biocides in controlling the microbiological

activity since monochloramines are not effective biocides. Historically Bromine based non-oxidizing biocides have been an industry standard with occasional Isothiazolin or Gluteraldhyde dosage. This paper discusses how mixed oxidants, as a combination of hypochlorite and peroxide, generated on-site replaced non-oxidizing biocides and improved overall water treatment regime at a major semiconductor facility in the US.

9:00a - 9:30aTP15-20 A Novel Biocide for Cooling Towers Improves System Performance and Reduces System CorrosivityChris Baron and Stephanie Hammond, Solenis

Chris Baron has been with Solenis (fka Ashland Inc.) for over fifteen years. His graduate thesis project at Purdue University involved sstudying the formation, equilibrabromanines and bromochlo-ramines. Other professional areas of interest include corrosion control and interfacing of analyticalinstrumentation with cooling and boiler systems.Traditional treatment programs for recirculating systems using strong oxidizing biocides often result in elevated general corrosion rates. A novel mild oxidizing biocide system that provides superior microbial control of cooling systems at considerably lower corro-sivity has been introduced. The novel biocide is produced on site

using dedicated feed equipment to convert a strong oxidizer, sodium hypochlorite, into a mild oxidizer that selectively targets mesophilic bacteria and algae without detrimental corrosive side-reactions. Typical performance improvements of cooling systems using this program include a substantial reduction in azole corrosion inhibitor feeds, increases in cycles of concentration, and decreased cleaning frequencies for condensers.

and has authored and presented technical papers on cooling systems. He is a member in good standing of the American Society of Mechanical Engineers (ASME). Since 1979 in a variety of assignments in Belgium, Mexico and the USA, Mr. Libert has acquired extensive cooling technology experience.In many areas of the globe water has become, along with energy, a critical natural resource. Because of that concern, a variety of hybrid cooling towers have been developed for power-plant usage. These hybrids provide the cooling performance of a wet-cooling tower but with less water usage. The particular amount of water savings that can be achieved varies with both the design of the hybrid cooling-tower and the ambient climate. There is no generally accepted method for estimating the expected water savings from a specific hybrid design at a specific site; nor is there a generally accepted method for verifying that the estimated water savings was realized. This paper proposes methods for both standardization of hy-brid water-savings calculations and verification of water savings by field measurements.continued in right column

• WTG-130A Corrosion Monitoring – Matt Wangerin - There is a document, WTG-149, that was reviewed (due for review) and was rolled over to the Board for the approval process. There is a Document in progress, WTG 130-A, a subset of the original WTG 130, that is also in review, and this document, WTG-130A, will be addressed by the group to determine if rewriting or editing is needed. The members of the group discussed where the draft document is at this time, and will try to locate the draft document.

• WTG-130B Deposit Monitoring – Dwight Emerich (reported) - Matt Wangerin and Pete Elliot have parts of the document which has been idle for a year or more due to the task group leader-ship vacancy. The group will restart the process. The document pieces have been located and will be reviewed. The group has defined the tasks facing them to move the document forward. They will summarize these tasks and forward them to Bob Cunningham.

• WTG-130C Microbiological Monitoring – Pete Elliot - The group had two meetings. They have the draft document and will continue to work on it via conference calls.

• WTG-158 Physical Water Treating – Paul Puckorius (reported) - The group has held some confer-ence calls since the winter meeting and has a scope and initial statement. These will be reviewed and then they will start on a “primer” of physical water treatment. Progress was made at this session. The group will continue via conference calls. They are targeting being ready for ad hoc review prior to the annual meeting.

• WTG-161 (old number was 159) Best Practices Guidelines for Cooling Water Systems – Jack Bland (reported) - Bill Pearson is the new vice-chairman. The group had two meetings. After the first meeting a committee comprised of Kim Kanuth, Ian Horne, and Jon Cohen produced a draft of the projected best practices table. This is currently in the form of a matrix of nine categories with “Good, Better, Best” measures, results or numbers for each category. The group will proceed via conference call prior to the Annual meeting.

Liaison Reports• IWC: Paul Puckorius reporting. The IWC meeting this fall will be in San Antonio. There are four

water treatment papers being presented. The dates and the workshop topics will be reported when available.

• AWT: Bill Pearson reporting. The AWT meets twice per year and conducts training sessions.

Water Treating Minutes from July 2013 continuedcontinued from page 11

• ASHRAE: Bill Pearson reporting. The ASHRAE meeting took place in Seattle two weeks ago. The committee TC3.6 is actively looking for research topics.

• NACE: Christine McGinnis reporting. Based on attending the last several meetings the in-terest at NACE has shifted away from water in favor of increased focus on oil and gas.

Additional Business:• Phil Kiser discussed the process of producing

documents for the CTI, providing a review of the OP 304. Phil stated that group chairmen should be aware of the steps of document pro-duction as set forth in the OP and should also take care to keep accurate attendance forms of the group’s meetings.

• The WTG 147 Water Reuse document is up for review and will be reviewed by Phil Kiser and Charles Kuhfeldt, as the chair and co-chair of the task group that produced the document, to determine if it needs a task group review.

• Helen Cerra provided an update of the review of Chapter 7 of the CTI manual. This has been under discussion as a cross functional group discussion with the ES&M section and is now under the working title of “Environmental Aspects” of cooling system operation, main-tenance etc.

• Chapter 6 of the manual, “Water Chemistry and Treatment” was last reviewed in 2005. Matt Wangerin, outgoing Water Treatment Committee Chairman, explained the status of this review, as follows, in summary.

Since most of the documents that are currently being worked on by the committee either revise or extend significant portions of Chapter 6, and given the limited resources of the commit-tee to undertake another entire chapter review while producing several new documents, the review of Chapter 6 was placed in the queue of work group assignments falling in place after the future completion of several of the exist-ing task groups papers. Then the new papers can be included in the revised Chapter 6 by reference or quotation.

• The Legionella Standard Task Group has voted down the creation of a standard as reported by Jack Bland. A revision of document No.159, the existing guideline, will be pursued.

• Helen Cerra noted that the CTI R&D commit-tee is soliciting new projects and asked that any idea be submitted to Phil Kiser. There is also the potential to collaborate with ASHRAE and AWT in pursuit of projects that we sug-gest. The discussion following this comment led to the recommendation of the group meet-ing noted above in the schedule of meetings.

• Discussion concerning the use of the Le-gionella group’s work and the information

gathered in that effort to enhance CTI’s definition of biofilms occurred. The question was whether this could be utilized by the group working on WTG 130 B. The chairman answered that the scope of the WTG 130 B group was how biofilm is monitored and that it would not change to include developing a new or enhanced definition at this time.

• Helen Cerra proposed that the group consider trying to answer the question or document previous data concerning how water treatment chemistry af-fects cooling tower drift rates. In discussion it was noted that Rich Aul has some information on this topic. Also the probable effects of biofilm on drift rates were discussed. No action was taken on this discussion at this time.

• Phil Kiser introduced the discussion of whether the water treatment com-mittee and its task groups should adopt the practice of having voting and non-voting members. This distinction is made in other CTI groups. The topic was discussed in some detail but no action was proposed or taken other than to introduce the topic to the group for further consideration.

• Matt Wangerin noted that the Water Treatment Committee sponsors a panel discussion at the fall CTI meeting which occurs on Monday afternoon and is 1.5 hours long. Topic suggestions were solicited and the following were offered:

Suggestions on how to write a proper bid specification Instrumentation and Control of Cooling Water Systems Reuse of water in Cooling Water Systems

• Phil Kiser, incoming committee chairman, thanked Matt Wangerin for his service as chairman for the previous four years.

Adjournment - The motion to adjourn was made and seconded and the meeting adjourned at 10:30 AM on the final day.

No Ties!The following is just a sample of the types of questions we get from those in every walk of life at the CTI office via our Website. Thanks to the Ask the Ex-pert Committee the CTI is able to reach out in another way to help those in the industry and those who have interest in the industry.Question 1We are going to be expanding an exist-ing wooden cooling tower that has the potential for seeing high pH material (up to 10) for weeks at a time. We would like to build the new portion of the tower from fiberglass. We are considering using vinyl ester resin for the wetted parts and polyester resin for the non-wetted parts. Do you see any issue with the ma-terial selection we plan? Will we encounter any problems with the mixing of materials?With a pH that high I would confirm with the Pultrusion supplier that the Vinyl-ester resign will survive for extended periods or indefinitely at a pH of 10. There are some inexpensive Vinylester resins that can approach the cost of polyester but they aren’t all that great. I don’t think I would mix the wetted and non-wetted sections with different FRP. I would recommend all Vinylester throughout the structure. There is some risk that the higher pH could cause blistering of the surface veil on the Polyester parts. For the difference in cost I would not risk it. In addition, I would suggest that when you are talking with cooling tower sup-pliers, you get them to let you talk directly to their pultrusion suppliers (no CTI manufacturers that I am aware of make their own pultrusions) to be sure they understand the nature of your application, and that you are serious about requir-ing all vinylester parts throughout. Otherwise, there is the possibility that some

polyester or “cheap” vinylester parts might be supplies. If this is an application that has been ongoing at your plant for some time, then you are no doubt familiar with the potential complications of a pH as high as 10, especially in your wood cooling tower.

Question 2In my company we have twin towers with capacity of 48,000 gpm and the area where we settled in the water is very expensive. Is there technology to recover water evaporated from our towers?The short answer is this: There is no technology out there, to recover the water that is evaporated from cooling towers, but there are several options to recover cooling tower blow down which involve UF/RO pretreatment and channeling the R.O. permeate back to the cooling tower’s Makeup water stream. Cooling tower blow down can also be sent to on site evaporators which will essentially boil the blow down water and recover the pure vapor for reuse as cooling tower makeup. The final option, and one that is seeing more play currently, is the use of mu-nicipal waste water by tapping into the city’s piping system, and pretreating this water by means of multi-media filtration, or precipitation, then maybe a UF/RO stage, dependent on the cooling tower makeup water quality desired or mandated.

Question 3The induced draft counter flow cooling tower is placed perpendicular to the sum-mer wind conditions, in low wind conditions the downwind wet bulb temperature

rises and the difference between upwind and downwind wet bulb temperature goes as high a 3 degrees C. Massive recirculation takes place and I have tested it by letting go of a baloon from the top of the fan stack. It gets sucked inside quickly.

1. Can I block the down wind of air inlet and force all air to inter from one side only?

2. Will its velocity pressure drop increase prohibitively at 1800 ft per minute (if one side is totally blocked)?

3. What is the maximum allowable inlet air velocity or is there no standard for this?

4. What is the maximum L/G recommended for such a tower?To answer your questions:1. It might be better to start by blocking half of the vertical height of the down-

wind air inlet from the top of the airinlet down. There is an advantage in better air distribution across the fill if you leave part of the downwind air inlet height open. closest to the ground, there will also be a certain amount of fresh air coming around the ends of the tower. Note also that closing the downwind air inlet reduces the total air flow, which reduces the air exit veloc-ity, which increases the recirculation tnedency.

2. Common practice is to limit to 1200 fpm and also to consider keeping the ratio of enterning velocity pressure below 1/5 of the tower pressure drop to avoid having air bypass the upwind perimeter of the fill.

3. It is believed to be more determined by the pressure ratio mentioned above than a velocity limit.

4. This is not generally a limit, being governed more by fluid mechanical limita-tion on air distribution and recirculation/interference.

Question 4We have a cooling tower with gas chlorine dosage point (one and only dosage point) to the main return water line, is this a “normal” point to gas chlorine dos-age? We think the usual is to dosage the C12 to the basin,. the cooling tower is under construction now and we want to know if this point of dosage is correct.There are three places that gaseous chlorine is generally introduced into a cooling tower system. The most commonly used application point is after the chiller/heat exchanger, which is your current design. While you will lose some chlorine due to off-gassing over the tower, you will keep the tower fill cleanest by feeding at that point and you will get good dispersion in the system. The issue with feeding into the basin or ahead of the chiller is corrosion. Dispersion in the basin is dif-ficult and can be the root cause of aggressive corrosion. Likewise, overfeeding ahead of the heat exchange device can be corrosive. So, you can feed in any of those points, but generally, gaseous chlorine is normally fed at the point you are currently planning to use.
