Effect of EPS on Membrane Pollution in IMBR

Abstract:

Using the IMBR processing simulation sewage test, The aim was to determine effect of EPS on membrane pollution in IMBR.The result showed that EPS was key to control membrane pollution during the system running 40 days. When EPS was between 14.85 and 19.44 mg.g^-1MLSS, the membrane pollution only rose from 12.74 to 36.26Pa.After accumulated with the continuous increase of EPS, membrane pollution was getting worse. At the end of the running of the system, EPS, polysaccharide content increased to 71.08 and 63.92 mg.g^-1MLSS. membrane pollution was271.46Pa. IMBR effluent quality was stable ,but membrane pollution was serious.
