…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.
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

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.

Elevation of surface charge density on colloidal particles in the presence of a high potential electrostatic field is demonstrated as a viable technique for preventing the accumulation of solids in solvent extraction circuits. This technique performs without introducing compounds that potentially interfere with kinetics or with phase separation.
