The effects of submerged microfiltration sequencing batch reactor (SM-SBR) process operation methods on membrane separation character and removal efficiency of organics and nutrients were investigated to minimize the membrane contamination and for simultaneous removal. The operation pressure of membrane separation was controlled to be maintained lower than critical permeable flux to minimize the membrane contamination which was defect of MBR process. The contaminated was intermittently fed into membrane to extend operation period. From these results, the SM-SBR process, use simultaneous removal of organics and nutrients, developed in this study can be used for small scale water recycle system.
