Zeta Rods installed into a Foxconn Reverse Osmosis (RO) plant in Shenzhen China increas­es per­me­ate rate from 66.6% to 76.4%,  reduces waste­water by 15% and pre­vents foul­ing of RO mem­branes allow­ing for ener­gy sav­ings and increased pro­duc­tiv­i­ty.

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.”

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.

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%.
