The U.S. Army Corps of Engineers Construction Engineering Research Laboratory and the Air Force Civil Engineer Agency evaluated a high voltage capacitance-based water treatment technology in evaporative cooling systems at four military installations in an extended study.  The non-chemical technology was evaluated for control and prevention of corrosion, scaling and biological fouling in a side-by-side comparison to standard chemical treatment.  Results confirmed that the technology delivered an average 20% reduction in make-up water and 48% reduction in blow-down wastewater, contributing to water conservation goals for agencies established under Executive Order 13423.  This paper presents the findings from the study.
