Impact of fouling index behavior in RO fed at different MBR operating conditions in MBR-RO.

The purpose of this study is to compare fouling index of reverse osmosis fed in MBR-RO systems at different operating conditions in MBRs. Lab. scale reactor of MBRs was operated at different flux and temperature and permeate was measured SDI15 to predict RO fouling rate. The results suggest that formed cake layer in membrane surface, higher flux and lower temperature in MBRs, led to lower RO fouling rates and SDI15 value was decreased, because of cake layer attached greater amounts of organic substances such as polysaccharide and protein.
