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

Abstract:
…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.

Mill Valley Car Wash water conservation, cost control and customer satisfaction
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

BP Manufacturing Solutions reduces chemical and filtration costs, GMPT Flint, Michigan USA

Highlights: Several positive outcomes resulted from the use of Zeta Rods. Because fungal growth in the high-pressure tanks was eliminated, production downtime was minimized. The fungal reduction reduced maintenance costs and improved operational efficiencies. Chemical usage also dropped, most notably in anti-foam due to the change in surface tension caused by Zeta RodsTM. This anit-foam reduction alone provided an annual cost savings of $120,000.

Feasibility Study for EDR Wastewater Treatment & Recovery

“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.”

AIChE Update: New Techniques Tame Biofouling
Chemical Engineering Progress | AIChE

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.
