…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.

Within 60 days, results delivered by the Zeta Rods were significant:
• Reduced water consumption per vehicle from 48.75 gallons per car (gpc) to 35.51 gpc; a net reduction of 27% per vehicle
• 235,000 gallons of water saved in 60 days
• 38% drop in the total per vehicle washing cost

“The Zeta Rod improved operability of the conventional RO treatment (relative to no pretreatment) although the mechanism responsible for the observed reduction in membrane fouling is not well understood. Feed pressures and WTC were more stable during Zeta Rod use at 50% recovery than without its use at 15% recovery.”

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.
