Evaluation of Zero Blowdown Cooling Towers with Soft Water Makeup

Cooling towers are ubiquitous equipment spread across a variety of sectors such as healthcare, hospitality, education, manufacturing, and real estate, and, if operated efficiently, perform the indispensable function of process heat removal through water evaporation. Efficient operation, however, is not the norm resulting in enormous water waste. Typical barriers to achieving efficient operations include the limited availability of skilled water treatment professionals and lack of diligent monitoring. This project sought to validate the claims of the WCTI technology to address some of the significant barriers to proper cooling tower maintenance and reduction in water use. The WCTI technology was able to control scale and corrosion but had poor bacterial control. Therefore, no conclusions as to the benefits of operating under WCTI operating regimen could be made.
