Review on Mechanism and Control of Membrane Fouling in Membrane Bioreactor

Membrane bioreactor(MBR) technology with advantages of improved effluent quality,small footprint,reduced sludge production and automated control over conventional activated sludge process,is viewed as a promising solution for wastewater treatment and reuse.However membrane fouling remains a major issue hindering its wide application.The paper aims to summary the advances on the mechanism and control of membrane fouling in MBR system.The research progress in membrane fouling classification,mechanism and factors affecting membrane fouling were firstly introduced.Accordingly advances on membrane fouling control were reviewed,based on which the development tendencies in the field were also discussed.
