WESCOM fights cholera with newest water purifi­ca­tion machine
by 6CRGAFP/RVC-PIA9 BaSulTa

ISABELA CITY, Basilan (Philippines)— The Western Command (WESCOM), has deployed its newest water purifi­ca­tion machine to barangay Culandanum in the munic­i­pal­i­ty of Bataraza in Palawan to help its res­i­dents recov­er from the trag­ic cholera out­break that struck the vil­lage, last March that left at least 27 per­sons dead.

BP Manufacturing Solutions Reduces Chemical and Filtration Costs at GMPT Flint, Michigan USA

BP Manufacturing Solutions reduces chem­i­cal and fil­tra­tion costs, GMPT Flint, Michigan USA

Highlights: Several pos­i­tive out­comes result­ed from the use of Zeta Rods. Because fun­gal growth in the high-pres­sure tanks was elim­i­nat­ed, pro­duc­tion down­time was min­i­mized. The fun­gal reduc­tion reduced main­te­nance costs and improved oper­a­tional effi­cien­cies. Chemical usage also dropped, most notably in anti-foam due to the change in sur­face ten­sion caused by Zeta RodsTM. This anit-foam reduc­tion alone pro­vid­ed an annu­al cost sav­ings of $120,000.

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

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%.

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.
