Zeta Rod systems remove biofilms that shield legionella

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. Continue reading

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.

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%.
