AWT’s (ASHRAE) Liaison Report presents and summarizes the recent ASHRAE research project, 1361-RP, on biological control in cooling water systems using non-chemical treatment devices. The report presents the result of ASHRAE’s controlled, independent, and scientific evaluation of several classes on non-chemical treatment devices (NCDs) for efficacy in reducing planktonic (bulk water) and sessile (Biofilm) microbial populations within a pilot-scale cooling system. The report also presents and summarizes a critique of objections to the ASHRAE research project.
