20% reductions in cooling tower make-up water and 50% reduction in blow-down were achieved at four U.S. Military Bases over a 24 month study period.
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.

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.
Bioshere 2 experiences dramatic improvement in the cleanliness of wet wall CELdek® media with use of Zeta Rod systems. Expected media replacement was unneccessary and the climate wall can operate at peak efficiency.
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%.
