R. Romo, M. M Pitts and N. B. Handagama. "Biofouling Control in Heat Exchangers Using High Voltage Capacitance Based Technology" ECI Symposium Series, Volume RP5: Proceedings of 7th International Conference on Heat Exchanger Fouling and Cleaning - Engineering Conferences International, Tomar, Portugal, July 1 - 6, 2007

…Four different application case studies are presented in this paper in which High Voltage Capacitance Based (HVCB) technology was used to control biofouling. The applications include an evaporative cooling wall in a greenhouse in Oracle, Arizona; a cooling tower–condenser application in Phoenix, Arizona (study performed by Arizona State University under a U.S. Department of Energy grant); a cooling tower system using reclaimed industrial waste water at a wafer facility in Camas, WA; and a piping system for a major utility plant (Tennessee Valley Authority – TVA) using river water.

Biosphere 2: Prevention of Biofouling and Scale in CELdek Wet Wall
Bioshere 2 experiences dramatic improvement in the cleanliness of wet wall CELdek® media with use of Zeta Rod systems. Expected media replacement was unneccessary and the climate wall can operate at peak efficiency.
