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 at GMPT Flint, Michigan USA

Link to GMPT Flint Success StoryZeta Library Collections: Case Studies

November 2001
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.
