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.

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.

Improving RO Performance with Zeta Rod Systems
After three months, the mem­brane was removed and the ves­sel was seen to be com­plete­ly clean. The mem­brane body, like the ves­sel surface,was com­plete­ly free of bio-film.The removal of biofilm from the mem­brane was evi­denced by a 4.98% increase in the rate of per­me­ate recov­ery, from 77.26% to 81.11%.
