Biosphere 2: Prevention of Biofouling and Scale in CELdek Wet Wall
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.

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.
