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.

Zeta Rod systems remove biofilms that shield legionella

Posted on by

Zeta NewsTucson, 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.

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.

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.
