Title:Evaluation of Zero Blowdown Cooling Towers with Soft Water Makeup

Abstract:Charles Curtiss - Illinois State Water Survey. Refrigeration, air conditioning, and process heat removal - ubiquitous operations employed by a variety of sectors - rely on cooling towers to avoid excess heat. The evaporative cooling of these towers, if operated efficiently, performs an indispensable function. However, efficient operation is often not the norm and can result in enormous water waste. Typical barriers to achieving efficient operations include lack of availability of skilled water treatment professionals, need for diligent monitoring, and need for regular use of hazardous chemicals. This project conducted by the Illinois State Water Survey (ISWS) evaluated a technology offered by Water Conservation Technology International (WCTI) that uses soft water to efficiently maintain and operate cooling towers. Maintaining the cooling towers in this manner would allow for less chemical use and also increase the cycles of concentration, thereby conserving water. The study involved cooling towers at the Champaign Regional Office Building and Chicago Data Center as well as two refrigerated warehouses in Minooka, IL.
