A sequential study was conducted comparing water treatment performance of traditional chemical water treatment and Dolphin "pulsed power" water treatment. The study was conducted o n the cooling tower for the University of Colorado (Boulder) ice rink. Feedwater for the tower was Boulder city water. Parameters evaluated were scaling, total bacteria, and uniform corrosion. Dolphin "pulsed power" water treatment was found to perform as well or better than chemical treatment when judged by the appearance of the chiller and tower fill, total bacteria counts, corrosion coupons, and cycles of concentration. Water, energy, manpower, and safety issues are presented. Show more
