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

Operations Manager Eric Traband: “I’m sold on this [Zeta Rod] system. What I have now is an odor-free and bacteria-controlled environment, I’m using a lot less water, and cutting my overall costs. This system is a winner.”

Within 60 days, results of the Zeta Rod installation into the Mill Valley Car Wash were impressive:
• 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

MILL VALLEY, Calif., April 2003 – Car wash Operations Manager, Eric Traband, recently demonstrated to his boss why he had been named a national Car Wash Manager of the Year in 2000. Traband, an 11-year veteran of the industry, seized an opportunity to help trim his carwash operation’s spiraling water costs and, at the same time, deliver better, more efficient service to his growing roster of customers.

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.”

CH2M HILL evaluates Zeta Rod & GrahamTek RO systems to reclaim EDR wastewater

CH2M HILL

CH2M HILL, a global leader in full service engineering, construction and operations, was tasked to find a way to treat the concentrate stream from a water treatment plant located in Sherman, Texas USA. The City wanted to be able to treat this wastewater in order to reduce sewer and wastewater plant loadings, and to recover a portion of the wastewater as high quality water than could be used to increase plant finished water capacity.

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.
