This presentation will allow you to understand the use of stabilized chlorine in cooling towers.
Traditional chlorination of cooling towers
Chemistry and efficacy of stabilized chlorine
Application of stabilized chlorine
Operation of cooling towers with high cycles of concentration is problematic for use of oxidizing biocides. Particularly with concerns about pathogenic organisms such as Legionella, the importance of microbial control in cooling towers is paramount both for public safety as well as heat transfer efficiency. Stabilized chlorine has shown advantages in high demand environments where oxidizing biocides may be quickly depleted. This presentation will discuss the chemistry of stabilized chlorine and its efficacy against microorganisms. Practical application information will also be provided.

Optimization of operation parameters in electrochemical methods for the removal of organic pollutants in sunflower oil refinery wastewater
Combined electrocoagulation (EC) + electrooxidation (EO) process was compared with electrochemical peroxidation (ECP) treatment process to treat sunflower oil refinery wastewater. The effect of applied current density, pH/H2O2 dosage, and operation time in the removal of COD, sCOD, TOC, and DOC were studied using Box Behnken Design. In EC process, decrease in organic concentration was observed as the time and current density increased. The optimized conditions for EC process were achieved at pH 6.07 when a current density of 5.69 mA cm-2 was applied for 18 minutes. The EO removed about 90% of DOC at an optimized pH of 5.27 and current density of 11.56 mA cm-2 when operated for 400 min. The combined EC+ EO process was successful in removing between 90-95% of organic pollutant from the sunflower oil refinery wastewater. The energy consumption was calculated to compare between the process efficiency of EC+EO and ECP. The reaction rate followed a first order kinetics validated with a high R2 Of more than 0.96.

The paper will assess pilot testing waters, methodologies and results from additives promoted for high LSI applications while presenting new data using state of the art equipment.
- Importance of Pilot Testing in Establishing Realistic Limits of Additive Performance.
- Case Histories that Show the Criticality of Establishing Realistic Water Chemistry and System Conditions
- Presentation of New Data which Demonstrate Realistic Failure Points using State of the Art Pilot Equipment
Independent water treatment professionals have utilized supplier data to support their integration and use of additives in their formulations and to define limits of use in field applications. While many suppliers utilize functional, bench top screening methods to compare additives, some suppliers also utilize custom built pilot test equipment. In general, pilot testing is considered to provide more realistic data that more effectively replicates field applications and defines the performance limits of the tested additive. In most cases, pilot testing does incorporate more complete and realistic water chemistry, heat transfer that more closely replicates field systems and operational parameters such as flow rate and velocity that make these evaluations much more credible and useful to the water treatment professional. In other cases, pilot data can utilize unrealistic conditions that suggest additive efficacy limits well beyond what could be pratically observed in field use applications.
The intent of this paper is to provide the membership with an overview of the importance of pilot testing in establishing an additive's performance limits, provide a survey of published data compared to industry use norms, and present new data which demonstrate realistic limits for currently used addtives in waters operating at LSI values above 2.5 and calcite saturation limits approaching 250X.

While Chlorine is one of the most widely used test parameters to determine water quality throughout the world, do we really understand the mechanism that Chlorine uses to achieve disinfection or removal of Biofilm? Or do we just accept and test? Understanding the background of the way in which Chlorine interacts with other components of the water system is fundamental to choosing the correct test for the application.
Since its identification in 1894, as a potential additive to water to eliminate germs, our understanding of Chlorine's behaviors and conditions needed to be effective have developed.
Early control of the Chlorine level was based on adding a fixed amount of Chlorine to a given volume of water, but as knowledge of disease control grew it soon became apparent that knowing the Chlorine residual levels at all times was more useful. The first test used to do this was a cumbersome iodiometric test using starch iodide. By 1908 this had been widely replaced by Ortho-Tolidine (OTO).
The popularity of the OTO method grew rapidly in the early part of the 20th Century as it was a good control method for the time. It was reliable and cost effective. It could be used by non-technical personnel and was readily available.
It was not until the mid 1930's that scientists gained an understanding of the break through point and Chlorination, which created the need for a test method able to differentiate between Free, Total and Combined chlorine.
In 1957 the DPD Method was introduced and, for many, has become the standard test used for Chlorine.
Over the last 100 years there have been several methods tried, tested and used.
In this paper we will discuss all the current methods being used, their application, interferences, pros, and cons and will unravel some of the mystery surrounding the reagent names and techniques.

The learners will understand the limitation of scale prediction simulations and indices
They will observe the application of indices and their meaning in typical cooling water
What are indices and saturation ratios
Where and how can a simple index such as the Langelier Saturation Index or similar indices for silica and calcium phosphates be applied?
When and why are more sophisticated appropriate?
Do indices mean the same thing in different systems and varying water chemistry?
is ther a relationship between indices. dosages and treatment failure points?
Predictive models and tests have evolved significantly since the marble test of the early twentieth century, the simple driving force indices such as the father of all indices, the Langelier Saturation Index in the 1930s, through the early speciation engines of the 1970s and onto the high ionic strength models of the twenty first century. Other models such as the Calcium Carbonate Precipitation Potential and momentary excess, predict the quantity of scale precipitation that might be expected.
This paper discusses the differences between the indices and their interpretation.
Simulating precipitation from untreated water is also discussed.

Attendees will gain an understanding of the technology and benefits of Physical Water Treatment (PWT) particle precipitator systems for suspended/dissolved solids management, control, and removal.
Water-cooled systems utilizing open-loop condenser water are in use in more than ten billion square feet of commercial, institutional, and industrial facilities throughout the United States. Chemical water treatments, along with continuous monitoring and control, maintain conditions in the recirculated condenser water loop to minimize unwanted conditions of mineral scaling, fouling, corrosion, and biological growth.
In 1998, the U.S. Department of Energy's Federal Energy Management Program issued a Federal Energy Alert describing the use of water treatment technologies using electric, electronic, or magnetic applications (also known as Physical Water Treatment, or PWT).
A PWT-based, particle-precipitator system exists to control and remove suspended/dissolved solids. This system is superior to traditional side-steam filtration systems and provides enhanced heat efficiency transfer throughout the entire cooling process. PWT technologies work alongside existing chemical treatment, and, in fact, reliably enhance the effectiveness of these systems. An effective side stream particle precipitator delivers the advantages associated with PWT applications. This presentation will review a decade of usage data at multiple facilities and highlight measurable, documented benefits in energy use, water use, and maintenance reductions. We will also illustrate the success of PWT through a case study involving a large university medical center, as just one of many well-established case studies.

Learner will see a variety of microbes present in wastewater treatment plants. Some approaches to optimizing wastewater treatment at pretreatment plants will be presented.
Photomicrographs of organisms from wastewater treatment plants will be shown (a photographic trip to the microbial zoo).
Soluble organic carbon/nutrients to microbial biomass, Predator/prey relationships, concept of trophic feeding levels,
Natural selection at wastewater plants
Public wastewater and pretreatment plants--structural comparisons
Hydraulic retention time and sludge retention time
Food:microbe ratio, Sludge age, Mean cell retention time
Boilers and cooling systems support production at food and beverage plants, chemical plants and other manufacturers. These processes produce wastewater that may go to on-site pretreatment facilities that process the waste prior to discharge to, frequently, the local sewer and subsequently the receiving water. Opportunities may exist for water treatment personnel to apply their knowledge of water chemistry, enhanced with some biological principles, and apply the information to the facts that their clients face at their pretreatment plants.
An abundant microbial population is crucial to the performance of biological wastewater treatment plants. Photographs of microbes in action will be provided to display diversity. Biological concepts of natural selection and trophic feeding levels are the basis for some methods to optiimize performance of wastewater pretreatment facilities.

Industrial facilities are continuously looking for ways to improve employee safety and to reduce environmental impact from their operations. Facilities that have multiple cooling systems distributed around a large site are often faced with managing many 20 and 200 litre containers which can have undesirable safety and environmental implications.
It is well known that solid form technologies reduce freight, CO2 emissions, operator handling and exposure and disposal volume to landfill over traditional liquid chemicals. The main challenge is to deliver a full water treatment program cost effectively in order to take advantage of these benefits across multiple chemicals and at the same time maintain or improve the program performance.
A project was implemented to convert all liquid cooling water chemistry to solid products at a large food production facility in New Zealand. Two of the seven cooling systems have been fully converted in 2019 and the remaining five will be converted in 2020.
The total program administered in this study includes a multifunctional corrosion and scale inhibitor, oxidising biocide, pH control and biodispersant all in solid form.
Safety risk has been improved by reducing the weight of each package by a factor of four. In addition to this the frequency of handling events has also been reduced.
Environmental impact has been improved by reducing transport related CO2 emissions by a factor of [TBC] across the total program. In addition to this, disposal of liquid packaging to landfill was almost eliminated.
Program performance improved substantially by improving refrigeration coefficient of performance by [TBC] while maintaining corrosion performance and microbiological control.
This paper describes how a total water treatment program can be administered using solid chemistries to maximize the safety and environmental gains associated with this form.

This presentation will demonstrate how on-site qPCR has both a strong positive and negative predictive value and is an advantageous tool to minimize Legionella risk.
1. It will demonstrate using a recently published study that Legionnaires' disease is common and underdiagnosed and how the disease prevalence may be attributed to the current methods used to detect Legionella in water systems.
2. For the first two case study, it will highlight the inaccuracies when using culture to determine Legionella quantification. It will demonstrate that performing on-site qPCR can minimize risk and prove the effectiveness of decontamination procedures.
3. For the third case study, completed at a healthcare facility, it was show that on-site qPCR when compared to traditional qPCR had superior positive predictive value relative to laboratory culture.
Shaimaa Ahmed, PhD.
HVAC cooling towers are a significant source of Legionella bacteria, the causative agent of Legionnaires' disease (LD). In a recent study, the frequency of Legionnaires' disease (LD) was assessed among pneumonia cases treated at a large community hospital over a summer season. Of the 33 patients tested, 9 (28%) were positive for Legionella. Three sets of the 9 Legionella cases exhibited spatiotemporal clustering indicative of LD outbreaks. It has been suggested that the prevalence of the disease may be linked to the methods used to quantify Legionella in water systems. The current standard for testing is laboratory culture which is prone to inaccuracies due to sample processing, and the requirement for shipping. On-site qPCR is not susceptible to these effects and offers a rapid sample-to-result turnaround time. We describe three case studies tested by both on-site qPCR and laboratory culture that highlight the advantages of on-site qPCR in determining the presence of Legionella in water systems. In all three cases, laboratory culture produced inconsistent or inaccurate results. Two case studies illustrate the value of a rapid on-site qPCR detection system for the monitoring and quantification of Legionella in HVAC cooling towers, as well as confirmation of decontamination procedures. Both of these case studies highlight the negative predictive value for qPCR. In the third case study, completed at a healthcare facility, it was shown that on-site qPCR when compared to traditional qPCR had superior positive predictive value relative to laboratory culture. Overall, these case studies indicate that on-site qPCR is a powerful tool to minimize risk to individuals as it has a strong positive and negative predictive value.

At last year's conference, I presented a paper titled, "Multi-Generational Water Treatment Companies – Leaving A Lasting Impact." The purpose of the paper was fourfold: 1) Increasing the awareness to do strategic planning, 2) providing helpful resources, 3) encouraging companies with stories of companies who have or are successfully working through the process of transition, and 4) providing next steps that an owner can take.
My goal for this year's proposed session is to provide more detail and specific next steps that the owner can take. We will inspire action when we can provide clear steps to take.
I am not an estate planning expert – I am not a lawyer or insurance expert. I am simply working the process myself and I believe keeping it simple (which is all I can do precisely because I am not a technical expert) will move people to take the action they should take.
Desired Outcomes would include:

The aim of this lecture is to provide attendees information about the existing standards, guidelines and regulations. The presentation will also focus on the efforts being made by the regulating agencies having jurisdiction and industry and professional associations working to develop standards to establish minimum requirements for supplemental disinfectants application.
Alberto Comazzi, PhD
Awareness of Legionella and Legionaries' disease by the public and the media has increased more in the last two years than in the previous two decades. One of the reasons this is happening is that, as reported by the Center for Diseases Control (CDC), the number of reported Legionaries' diseases cases have increased by a 4x factor in the last ten years.
Despite the fact Legionellosis is a well know diseases and it's very clear how the infection can be contracted, there is not a universal technique that ensures a 100% efficacy on the disease prevention.
The first step buildings owners and managers shall take is to establish a water management team and develop a water management plan. Various industry associations and organizations (NSF, ASHRAE, ASDWA, AIHA) are developing standards and guidelines to assist facilities in developing water safety plans and implementing remediation technologies.
There are several technologies that are available, including non-residual techniques (UV and ozone) and methods that are able to establish a chemical residual in the building water system, also know as "supplemental disinfectant" (chlorine, monochloramine, chlorine dioxide, ionization). Among all the methods here reported only chlorine, monochloramine and chlorine dioxide are listed as disinfectants under the EPA-Safe Drinking Water Act.
Despite there are several disinfection options and technologies that a facility owner/manager can implement in the building, there is no uniformity on the requirements that a disinfectant/technology has to fulfill in order to be permitted by the agency that has jurisdiction.
The only federal regulation that applies to the whole country is the National Primary Drinking Water Regulations (40 CFR 141). The regulation applies to community water systems and non-transient non-community systems. The definition of non-transient non-community systems (NTNCWS) is "A public water system that regularly supplies water to at least 25 of the same people at least six months per year". It is easy to understand that buildings such as hospitals, nursing homes, hotels, condominiums and dormitories all fall under this category.
This definition puts the building owners/managers in a difficult position because the addition of a disinfectant (treatment) to drinking water subjects the facility to the same requirements of a public water supply. The States are responsible for the enforcement of this rule, but the regulating agency having primacy may vary on a State by State basis (DOH, EPA, and DEP). The requirements can vary in each State, for example Florida requires a permit only for cold water applications whereas New Jersey doesn't require a permit at all. This inconsistency confuses the owners and managers and often makes them feel that they are the only ones that are going to have to deal with this serious public health matter.
The purpose of this presentation is to educate the audience on the state of the art about the existing regulations, standards, guidelines and permitting requirements and the efforts that should be made by the regulatory agencies in order to get a consensus and minimum requirements when a supplemental disinfection system is in installed.
Dr. Alberto Comazzi earned a PhD in Industrial Chemistry from the University of Milan. His research during his academic experience was focused on the study of the stability and the interaction among different chlorine based water disinfectants. Alberto is a member of the ASHRAE SSPC 188 committee.
Dr. Comazzi currently works as Technical Director in Sanipur US, based in Philadelphia PA. Sanipur US distributes and provides technical support for the production and application of supplemental disinfectants for Legionella remediation in building utility water systems.

Legionella is an Opportunistic Waterborne Pathogen that exists as a free-living organism and an intracellular parasite in which several amoeba species serve as the host organism. Often the life cycle of Legionella is portrayed as dependent upon the existence of an amoeboid host which is present in a complex biofilm community. Whether this host-parasite relationship is a necessary or an opportunistic relationship is not well understood. In this paper, we examine potable and non-potable (cooling tower water) water systems for the presence of Legionella spp. and amoeba. We use conventional culture techniques to determine the presence of and quantify Legionella spp. and a LIVE/DEAD® stain to determine the presence of and quantify live and dead amoeba. The LIVE/DEAD stain uses the dyes Syto 9® and propidium iodide to render viable amoeba green and dead amoeba red respectively using epifluorescence microscopy. This technique has been used on other eukaryotic cells but not on amoeba. Data was analyzed to determine if (1) a correlation exists between the presence of amoeba and Legionella spp. and (2) the presence of amoeba is correlated with the type of disinfectant used. Data from an in vitro evaluation of conventional oxidizing biocides will also be presented.

Show practical ways to protect companies from these risks
Provide examples from case studies so the information can be understood in applied settings
All topic points will be presented by Michael Reinert
Cybersecurity is a term we are all familiar with, however the typical information about cybersecurity is very confusing and therefore most people and companies don't take practical steps to better understand and protect themselves from cyber attack. While there are many ways to discuss cybersecurity one easier way is to understand that it is now a risk to companies like many other risks including physical theft or damage or man-made or natural disasters. Businesses mitigate risks everyday to protect themselves and their hard won successes. Cybersecurity should be viewed as a similar risk and companies should take similar steps to protect themselves. This presentation will focus on a basic understanding of cybersecurity risks and practical ways to protect companies from these risks. I will define cybersecurity and associated risks, discuss practical methods to mitigate these risks, and give examples from case studies so the information can be understood in applied settings.

In today's tight labor market many of us in the water treatment industry continue to struggle to attract the right talent to meet our growing business needs. The fact is many companies -regardless of size – simply rely on traditional methods for recruiting, interviewing, and selecting individuals in the hopes of landing an acceptable candidate to hire. Basically, casting rods into the water and hoping to pull up the big fish. Sometimes we get lucky; many times, we come up empty.
To break this cycle of casting rods into the water and not getting the results we desire, we need to ask ourselves a few questions. How can we become smarter and more efficient with attracting, recruiting, and building a talent pipeline to fill our hiring gaps? How do we break from traditional recruiting methods to explore "outside the box" methods? How do you get individuals interested in the skills necessary to work in an ever-increasingly technology-driven industry?
By attending this session, you will learn real life tested "best practices" to strategically engage and attract future employees by developing a community-based talent pipeline. Find out what techniques succeeded and those that may require a little more time and attention. Implement strategies that provide the opportunity for regular, ongoing interaction are required to create and maintain these important relationships. These inlcude commnuity engagment, partnerships with local schools, and involvment in local organizations.
Help your company stand out in a tight job market and start building your pipeline of talent immediately. You'll learn that it doesn't have to begin with a vast amount of resources or labor; rather from a few well-meaning partnerships, you'll be able to attract a talented, engaged, and properly motivated workforce to meet your growing business needs.
The main objective of this presentation is to teach the audience that disinfectant residuals in potable water from building water systems with copper-silver ionization secondary disinfection systems may require different sample preservation approaches in order to neutralize copper and silver disinfectant residuals during transit to a laboratory for Legionella testing, and that an EDTA/sodium thiosulfate cocktail will serve this purpose.
- Building water samples collected for culture detection of Legionella generally have an added reducing agent, such as sodium thiosulfate, to neutralize chlorine or other halogen disinfectant residuals, in order to prevent bactericidal action from continuing during transit to the laboratory.
-Disinfectant residuals in potable water from building water systems with copper-silver ionization secondary disinfection systems may require different sample preservation approaches in order to neutralize copper and silver disinfectant residuals during transit to a laboratory for Legionella testing.
- Research by Resgalla et al. (Chemosphere 89, 102-107, 2012) has shown that EDTA and sodium thiosulfate will neutralize the toxicity of copper and silver in water, respectively. We will present our results, adding EDTA + sodium thiosulfate formulas to potable water samples containing copper and silver ions, thus preventing the continuing bactericidal action of Cu and Ag ions during transit and providing a more accurate Legionella culture result.

Water samples collected for culture detection of Legionella generally have an added reducing agent, such as sodium thiosulfate, to neutralize chlorine or other halogen disinfectant residuals, in order to prevent bactericidal action from continuing during transit to the laboratory. However, disinfectant residuals in potable water from copper-silver ionization secondary disinfection systems may require different sample preservation approaches in order to neutralize copper and silver disinfectant residuals. Metal chelating agents, such as ethylene-diamine-tetraacetate (EDTA), have been recommended for this purpose. A study by Resgalla et al. (Chemosphere 89, 102-107, 2012) has shown that EDTA effectively removed metal toxicity of copper in water. Silver toxicity was not removed by EDTA, but was removed by sodium thiosulfate (at concentrations used for de-chlorination). However, EDTA chelation of metals does have some anti-bacterial activity at high concentrations. Thus, the purpose of the present study was to evaluate the ability of EDTA/thiosulfate formulas (at different EDTA concentrations, EDTA salts, and pH not harmful for Legionella), to neutralize the metal toxicity of water from building water systems that are using a Cu/Ag secondary disinfection system. We will present our findings on the addition of such a cocktail to water samples collected for Legionella culture-based validation of control by these Cu/Ag ionization systems, thus preventing the continuing bactericidal action of Cu and Ag ions during transit and providing a more accurate culture result.

Janet E. Stout, PhD
Outbreaks among hospitalized patients are caused by waterborne pathogens other than Legionella and occur on a regular basis. These include surgical wound infections, respiratory infections due to brochoscope contamination, dental line contamination, sink drains and ice machines. These outbreaks prompted the Center for Medicare and Medicaid Services (CMS) to add other waterborne pathogens to the 2018 memorandum requiring healthcare facilities to have water management programs to control the growth and spread of Legionella. CMS specifically included Pseudomonas, Acinetobacter, Burkholderia, Stenotrophomonas and non-tuberculous mycobacteria (NTM).
Water treatment professionals are now expected to advise healthcare facilities about the risk and management of both Legionella and other waterborne pathogens. The level of knowledge and skill necessary to meet this expectation crosses the disciplines of epidemiology, infection control and infectious diseases, plumbing design and construction. Resources are needed to provide the necessary knowledge to meet these challenges.
Furthermore, all waterborne pathogens are not created equal with respect to detection methods, risk and mitigation. Learn why hospital laboratories may not detect these pathogens and why Legionella prevention approaches are not effective against all waterborne pathogens such as Pseudomonas, Acinetobacter, Burkholderia, Stenotrophomonas and non-tuberculous mycobacteria.

In this state of the industry, the moderator will lead an esteemed panel discussion. Panelists will share their personal experiences throughout their careers using limited data sets to solve water related issues and the challenges that has historically presented, as well as illustrate how that is changing with better data collection methodolgies. Better data produces better outcomes.
Moderator will prompt a short discussion following each experience.
This will lead into a discussion of present-day analytics, Internet of Things (IoT), and how it fits into the landscape of our industry.
Smart building management has arrived! Smart building technology encompasses security, elevator, HVAC, and lighting control.
The question is 'When will owners demand smarter data driven solutions from their water treatment partners to support risk management objectives?' The tide is turning with expectations of water management professionals in managing inherent water related risks in buildings.
Major concerns in facilities operations includes the protection of capital assets, occupant safety and operational efficiency of mechanical equipment. These risks will be identified and discussed in a round table setting to explain the changing role of the water management provider. Doing more with less is the rallying cry in the data age. Data science is now offering a more timely, accurate and precise way to support the management of these omnipresent risks. Panelists will highlight ways that data analytics is driving solutions to water related risk.
The roundtable will close with the moderator reviewing frequently asked questions and subsequent audience Q&A.
In 2016 HydroChem Australia constructed a new production facility introducing several innovations:
The technologies were introduced with a number of aims:
As an example, it is now possible to blend water treatment chemicals without any human interaction with the equipment. In addition, when packing into 15 litre drums, all filling, capping and labelling is handled on automated production line (with robot arm). Please see images in attachment.
In the three years since the system was introduced, HydroChem Australia has recognised significant improvements. This presentation will explain the process and provide an analysis of the benefits realised in comparison to traditional manufacturing processes.
HydroChem Australia introduced a client portal in 2016 to provide clients visibility and visualisation of their data.
HydroChem Australia is responsible for over 5,000 locations. A number of national clients have portfolios of 50+ complex locations with 10+ assets on each location. Those assets represent significant risk to the clients in terms of potential asset damage and potential for Legionnaires' outbreaks.
From a client perspective, it is not unusual for 2 or 3 asset managers in a central location to be tasked the responsibility for maintaining all assets across a complex national portfolio.
The Clarity Portal delivers a number of benefits (see images in attachment):
This presentation will describe the features of the portal, the development process (not too IT technical) and the unexpected advantages to HydroChem Australia's account managers.
Agriculture and Thermoelectric Power Generation draws almost 90% of fresh water. The trend in electricity generation is moving towards renewal resources such as wind, solar and geothermal, which requires very little water. These new resources reduce the green-house gasses and water usage. However, harvesting Geothermal energy as a renewal resource requires a great deal of water treatment. The paper discusses in depth the challenges facing the geothermal industry for managing the geothermal brines, maximizing the energy recovery, and asset protection. Different segments of a geothermal plant have unique challenges and require innovating solutions. Most of the geothermal plants also have unique designs based on the enthalpy and the brine chemistry of the resource. American Water Technologists have excellent solutions for water treatment and are very familiar with handling the basic problems of scale, corrosion, deposit and biofouling. Geothermal systems have the same challenges and require similar solutions, however, under different environment, which are discussed in this paper.
The objective of this Cooling Committee Technical Paper is to outline a water treatment management plan designed to improve program performance and limit liability concerns at cooling water accounts by establishing a Shared Responsibility Management Agreement between the Water Treatment Service Company (WTSC) and the Facility Management Staff (FMS).
Ken Soeder will be presenting on behalf of the Cooling Committee.
In all open recirculating cooling water systems, even the most technically-advanced water treatment products will not make up for poor product application or inconsistent system control. Without proper oversight, cooling water systems can quickly become susceptible to a wide range of operating problems, including increased corrosion rates, scaling and deposition problems, and increased microbiological activity. Over time, these problems can contribute to shortened equipment service life, increased electric and water consumption rates, poor product quality, and even possible health concerns, such as Legionnaires' disease. In worst case scenarios, these problems can even lead to costly and time-consuming litigation. These types of problems can be most apparent in small to mid-sized accounts, where the Water Treatment Service Company (WTSC) may only conduct service visits on a bi-weekly, monthly or even quarterly basis, and program oversight by the Facility Management Staff (FMS) is now typically modest or even non-existent.
However, proper system control and excellent results still can be achieved if the WTSC and FMS work together to fully identify, understand, and document their individual responsibilities for program supervision, testing, and reporting. Effective control of water treatment systems in any facility requires both the product and technical expertise of the WTSC and the day-to-day oversight of the FMS. The WTSC has the background and knowledge to select an appropriate water treatment program, supply the necessary products, set up the required system monitoring and testing equipment, and to periodically visit the site to review program compliance. The FMS is present at the building on a daily basis, and is actually in the best position to ensure that the water treatment program is operating as designed. As such, the knowledge, expertise, and time commitment of both entities working together is ultimately required if the program is to be successful.
The AWT Shared Responsibility Water Treatment Agreement, developed by the Cooling Committee, is essentially a signed document developed between the WTSC and the FMS which outlines the tests and tasks that are to be performed on a routine basis by each responsible party. It recognizes that the WTSC cannot be at the facility each and every day, so certain tasks must be performed by the FMS to ensure the consistent and successful operation of the cooling water treatment program. The objective of this document is to present written guidelines that outline the specific tests and tasks that should be conducted by each party to insure the successful operation of the water treatment program. It must be stressed here that we are presenting "Guidelines" that are to be used by the individual WTSC and FMS to develop a program that is specific and useful to their water treatment program and building staffing requirements. Not all of the test procedures or oversight tasks outlined on each Guideline needs to be incorporated into the final agreement. You may even wish to include some new test procedures or tasks of your own that are not even listed on the current Guidelines. However, many of the routine tests outlines in the agreement, such as conductivity, pH, temperature and ORP measurements, can now be conducted using modern digital system controllers with data logging and cloud reporting capabilities. As the size of the cooling water system increases, and more routine service visits are provided by the WTSC, the overall burden of program testing and oversight on the FMS is reduced.
With a properly prepared and executed "Shared Responsibility Management Agreement" between the WTSC and FMS, both parties should have a document that clearly outlines specific testing and task responsibilities, improves program performance, and minimizes the possibility of legal action. Once completed, the Shared Responsibility Management Agreement can then be used as a stand-alone document, or more commonly as an addendum page in a new proposal or contract.

Ronit Erlitzki. PhD
High recovery processes and waste-stream or concentrate management are key issues when considering any water treatment solution, whether is filtration, adsorption, or reverse osmosis (RO) for desalinization.
Increasing recovery rate and reducing the volume of RO concentrate creates significant savings (CAPEX & OPEX) while demonstrating environmental responsibility and water stewardship.
This presentation will focus on the Flow-Reversal RO technology that employs conventional RO equipment with 2 unique principles: Flow-Reversal and Block Rotation. Flow-Reversal, whether it is a new RO system or a retrofitted one, is a continuous process that does not use any proprietary equipment, does not require any special operator training, and can operate as conventional RO (if needed).
The process, which is suitable for different types of reverse osmosis applications, reduces scaling and biofouling, and results in very high recovery rates.
We will explain how the technology works, generates savings, and facilitates concentrate management by presenting examples of different applications (reuse, concentrate recovery, brackish water, and multiple contaminant situations), focusing on a case study of Flow-Reversal RO retrofit in a beverage plant in the US.

Andrew K. Boal, Ph.D.
While a variety of both oxidizing and non-oxidizing biocides are used to disinfect waters in cooling towers, aqueous bromine is one of the most common biocides used for this application. Since hypobromous acid is present in greater relative amounts in the high pH environment typically found in cooling towers, aqueous bromine is often considered to be a superior disinfection option relative to other oxidizing biocides, despite the increased costs associated with the use of bromine. Aqueous bromine can be introduced into a cooling tower either through the addition of sodium bromide in conjunction with sodium hypochlorite or chlorine gas or by using delivered stabilized sodium hypobromite solutions. While these options can deliver the desired aqueous bromine to the cooling tower being disinfected, they are accompanied by operational challenges such as complex injection controls, high operational costs, and the requirement of handling hazardous chemicals. Electrochlorination systems have long been used to address similar issues when treating water with aqueous chlorine by making sodium hypochlorite-based oxidant solutions on location and on demand using only salt, water, and electricity. Recently research and development has enabled the use of this same process to produce aqueous bromine solutions through the electrolysis of brines comprised of sodium chloride and sodium bromide with the addition of sulfamic acid as a bromine stabilizing agent. This paper will present the chemical and engineering aspects of this process and discuss how aqueous bromine solutions produced through electrohalogenation can be used as part of an overall cooling tower water treatment program.

With Legionnaires' disease outbreaks continuing to make headlines, the "other" opportunistic building water pathogens can be overlooked, by water management professionals and their busy customers. Yet Pseudomonas aeruginosa is a major source of expensive healthcare acquired infections, is one of the top causes of outbreaks from pools and spas and is even identified as a concern in cooling towers in some countries. Water treaters increasingly need to understand where Pseudomonas aeruginosa is most likely to be found, where it should be of significant concern (and where not!) and how to help minimize its risk of causing disease, whether that disease is likely to be fatal or simply unpleasant.
Why and where exactly is P. aeruginosa a concern? According to the CDC's 2019 Antibiotic Resistance Threats Report, in 2017, "multidrug-resistant Pseudomonas aeruginosa caused an estimated 32,600 infections among hospitalized patients and 2,700 estimated deaths" leading to extensive healthcare expense. P. aeruginosa is particularly dangerous in neo-natal units and tragic outbreaks with multiple infant deaths occurred in 2017 and again in 2019. Water plays a major role in P. aeruginosa infections in hospitals where there are numerous "reservoirs" for the bacteria: potable water, faucets/taps, sink and shower drains, respiratory equipment, humidifiers, endoscopes, water baths, hydrotherapy pools, etc. (Bedard, 2016) Risk should be assessed, and appropriate control measures considered for each of these sites. "Swimmer's ear" and "Hot tub rash" could be seen as mere inconveniences, but each can also lead to outbreaks, pool/spa closures and a lasting stain on the reputation of hotels and leisure facilities. Potential sources of these diseases also need to be contemplated in a water management plan. Finally, from an occupational safety perspective, P. aeruginosa can cause illness during cooling tower maintenance and cleaning (Wiatr, 2002), as well as metabolize nitrogen-based corrosion inhibitors, leading to corrosion issues. (Spies et al, prepublication manuscript.)
What do current guidance and standards documents say about P. aeruginosa? This presentation will review the Water Management Plan expectations for CMS covered hospital and long-term care facilities relative to Pseudomonas aeruginosa. The presenter will also bring attendees up to speed on the most recent work on Pseudomonas aeruginosa risk reduction being worked on by industry organizations. To provide examples of how others respond to this risk and what might be coming in the future to North America the presenter will cover regulations in other parts of the world, including the UK, France, and Germany.
What does research say about tools that can be used to detect and measure P. aeruginosa? The industry standard for detecting P. aeruginosa is by a culture method performed in a laboratory. Traditionally, culture tests have been performed on hot and cold tap water as well as on treated pools and spa water. Culture testing of biofilm samples collected by swab techniques is also common. Recently, culture methods for detecting and quantifying Pseudomonas aeruginosa have been pushed even further. This presentation will include results from a study by German researchers who have tested highly contaminated cooling tower water n the hopes of identifying more streamlined ways to meet that country's new cooling tower pseudomonas monitoring requirements.

The opportunistic, waterborne pathogen Legionella caused 9,933 cases of Legionnaires' disease in 2018 in the United States (CDC.gov). The incidence of Legionnaires' disease can be reduced by maintaining clean building water systems through water management programs (WMPs). WMPs often include validation testing to confirm the control of bacteria, but the traditional culture method for enumerating Legionella requires 10–14 days to obtain results. A rapid DNA extraction developed by Phigenics and a real-time PCR negative screen for the genus Legionella provided results the day after sampling. This study evaluated the Next Day Legionella PCR (Phigenics, LLC) compared with the traditional culture method (ISO 11731) on 11,125 building water samples for approximately 1 year. Two DNA extraction methods (Methods 1 and 2) were compared. The negative predictive value (NPV) of the Next Day Legionella PCR in comparison to traditional culture for Method 1 was 99.95%, 99.92%, 99.85%, and 99.17% at >10, >2, >1, and >0.1 CFU/ml limits of detection, respectively. The improved DNA extraction (Method 2) increased the NPV to 100% and 99.88% at >1 and >0.1 CFU/ml, respectively. These results demonstrate the reliability of the genus-level Legionella PCR negative screen to predict culture-negative water samples.

The goal of this presentation is to illustrate why it is important for water treaters to generate quality reports and maintain access to historical data.
Adam Dumler – all topics
During this presentation attendees will learn about the importance of quality reporting and access to historical data from both the strategic and technical perspective. Many water treaters provide services to their customers that are ultimately documented through reports that are shared with the end customer, however not all reports are created equally.
Some water treaters are of the mindset that reports are simply a routine task which causes them to underappreciate the benefits that come with sharing a thorough, professional-quality report with the end customer. This presentation reviews the different components that are found in high quality reports regardless of industry or company size. Attendees will also be shown examples of different types of services that can be documented as well as how they are perceived from the customer's perspective.
In addition to reporting quality, water treaters in today's environment encounter competitive and regulatory challenges that they must overcome in order to achieve success. Many of these challenges related to the consulting aspect of water treatment can be addressed through not only quality reporting but also thorough access to historical data. By establishing a reporting standard within their own organization, water treaters will improve the quality and usefulness of the historical data created. This data can be utilized when facing regulatory or competitive challenges.
The value of data is not limited to reporting; many of the feed and control equipment solutions in the market today have the capability to provide historical data from an additional perspective. The presentation discusses the different types of data that can be collected and how the water treater can utilize this information to better improve the quality of the services they provide.
Through a combination of quality reporting and access to historical data, the water treater can be prepared to fully utilize the consulting aspect of water treatment to achieve success in their respective industries.
Adam Dumler is one of the founding members of H2trOnics, Inc. which has become a part of the AquaPhoenix family through a recent acquisition. He has nearly two decades of experience working with water treatment companies of all sizes both domestically and internationally to provide the guidance and tools needed to enhance the consulting aspect of water treatment. Throughout the years he has worked with employees at every level within a water treater's organization – from business owners to sales reps and even the end customer – in order to gain an understanding of what each role's expectations are with regards to reporting. This presentation provides a summary of his knowledge about the importance of both quality reporting and access to historical data.
Attendees will learn how digital dashboards allow the water treater to help their customers make smarter decisions faster, and use precious resources more efficiently.
As plant engineers are forced to do more with less--to do more to protect their assets, prevent downtime, conserve water, save energy, and practice good water safety--technologically innovative water treaters have an opportunity to help them. Internet-connected smart controllers can collect sensor data in multiple buildings at each of multiple facilities; a digital dashboard can then gather all of this data together, perform customer-specific calculations, and present the information that is most relevant to operators, engineers, or corporate personnel. This focused, real-time visibility into geographically widely separated facilities helps both the customer and the water treater to make smarter decisions faster, and to use precious resources more efficiently. Three case studies are presented, each highlighting a benefit of the digital dashboard approach.
