From the author: A field study was conducted to evaluate the performance of a hydrodynamic cavitation device (HCD) for disinfection, scaling, corrosion, and heat-transfer efficiency on a cooling-tower system at an automotive testing facility. Primary findings are: (1) The HCD unit performed as well as the chemical program that it replaced in terms of bacterial control without adding any chemicals (including disinfectants); the bacterial count was maintained at ~[10.sup.4] cfu/mL over the course of the study. (2) The HCD unit enabled the cooling system to be operated at comparable cycles of concentration (CoC) to that used during the chemical program, without adversely affecting pH, scaling, or corrosion. (3) The corrosion rates of copper and mild steel were either equivalent or better than those obtained during the chemical program. (4) The use of the HCD unit did not adversely affect heat-transfer efficiency. Long-term effectiveness of this technology was not evaluated as part of this study.
