 Cooling System Filtration: Methods & Benefits Webinar

​Presented on April 4, 2017, by Walt Kozlowski and Bob Bradley, this webinar explains how cooling towers can collect significant amounts of airborne contaminants that can reduce system efficiency, be a site for growth of bacteria and organisms, and result in increased usage of water treatment chemicals. Sidestream filtration is discussed and recognized as a method to reduce contaminants.

 

 About the Webinar

Open recirculating cooling systems are used in many industrial plants. Cooling towers, a critical component in these systems, reject waste heat to the atmosphere by evaporating water but also act as air-scrubbers and can collect significant amounts of airborne contaminants. These contaminants often build up to significant levels in the system and are not efficiently removed by normal tower blowdown, which can result in fouling that reduces system efficiency, can be a site for growth of bacteria and organisms, and result in increased usage of water treatment chemicals.

In closed cooling system loops, corrosion by-products such as iron/rust can foul heat exchangers, create locations for bacteria to proliferate, and result in under-deposit corrosion issues.   


Sidestream filtration is a recognized method of reducing contaminants in both open and closed recirculating water systems.  Both the US Department of Energy and the cooling tower manufacturers advocate the installation of a filter on these systems as a best practice.  This webinar will review some of the fouling and bacterial issues caused by contaminants in cooling systems, and will present the benefits and methods of various filtration techniques.
