…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.
Zeta Rod systems successfully provide water conservation, chemical eliminations and reductions, biofouling & scale prevention in this PVC plant.

Tucson, Arizona: Zeta Corporation has established that its patented Zeta Rod® technology is another weapon in the battle against legionella. Zeta Rod systems will remove and prevent recurrence of biofilm and associated scale that shelters legionella bacteria inside potable water systems and in cooling towers. Continue reading
Tucson, Ariz., April 10, 2002 — After three years of closely monitored performance at the Los Angeles Convention Center of Zeta Corporation’s Zeta Rod™ system, the convention center won a city-wide environmental award and realized a three-year accumulated savings of $150,000.
Zeta Rod System at Los Angeles Convention Center
In making the announcement, Zeta President M. Michael Pitts, Jr, Ph.D. said that the City of Los Angeles Quality and Productivity Commission, after an eight-month evaluation process, singled out 20 city departments out of 114 applicants for honors in the categories of Customer Service, Environmental, Entrepreneurship, E-Business and Innovation and Creativity.
The Los Angeles Convention Center facilities staff won the Environmental Award for “the elimination of scale and corrosion cleaning, increased employee safety, reduced water consumption, longer equipment life and an annual savings of $50,000” in the operation of the huge building’s chillers and cooling towers.

Biofouling plagues many plants in the chemical process industries. Ongoing research is focusing on ways to control a range of bioorganisms, ranging from fungi to zebra mussels, that can cause these problems. Chlorine Pulsing, Electronic Rods [Zeta Rods], filters, anti-microbial coatings and corn-based polymers are discussed. Click here to link to the AIChE CEP Magazine article.
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.
