The topic of Non Chemical Device (NCD) water treatment seems to always be popular. ASHRAE Project Number 1361-RP focused on Biological Control in Cooling Water Systems using Non-Chemical Treatment Devices. Five different NCD devices were analyzed in the study from the following categories: Magnetic, Pulsed Electric Field, Electrostatic, Ultrasonic, and Hydrodynamic Cavitation.
The experiment concluded, "...no statistically significant difference...in planktonic or sessile microbial concentrations (HPC) was observed between the control tower and a tower treated by any of the five NCDs evaluated in this study...", (i-ii).
