Salt cleaning of organic-fouled reverse osmosis membranes.
Cleaning of organic-fouled reverse osmosis membranes with concentrated salt solutions has been investigated. Polysaccharides (alginate and pectin) and Suwannee River natural organic matter were used as model organic foulants. By systematically varying the chemical and physical factors affecting salt cleaning efficiency, we were able to elucidate the processes and mechanisms involved during salt...
متن کاملForward osmosis membrane fouling and cleaning for wastewater reuse
Membrane fouling properties and different physical cleaning methods for forward osmosis (FO) and reverse osmosis (RO) laboratory-scale filtration systems were investigated. The membrane fouling, with respect to flux reduction, was lower in FO than in RO when testing an activated sludge effluent. Crossflow velocity, air-scouring, osmotic backwashing and effect of a spacer were compared to determ...
متن کاملFouling and cleaning of reverse osmosis membrane applied to membrane bioreactor effluent treating textile wastewater
Membrane bioreactor (MBR) and reverse osmosis (RO) membrane system was applied to the treatment and reclamation of textile wastewater in Thailand. An experiment was carried out to determine the fouling behavior and effect of anti-scalant and biocide addition to flux decline and its recovery through chemical cleaning. The RO unit was operated for one month after which the fouled membranes were c...
متن کاملChromium Removal from Wastewater by Reverse Osmosis
This study describes the removal of chromium from wastewater using pressure-driven membrane separation processes. It describes the rejection of trivalent chromium using a commercial membrane for reverse osmosis typed RO98pHt (Alfa Laval, Sweden). Model solutions of chromium were used for performing of separation experiments. The effects of feed pH, chromium concentration and temperature were in...
