Discussion on Measures for Lessening Membrane Fouling in Membrane Bioreactor

Membrane bioreactor(MBR) is a kind of wastewater treatment process in which membrane separation technology is coupled with the biological wastewater treatment technology.It has many advantages compared with the conventional wastewater treatment processes.However,membrane fouling restricts the widespread application of the process.The definition of membrane fouling was presented,the progress in membrane fouling research were thoroughly reviewed,and the technical measures for lessening membrane fouling effectively were introduced from three aspects of ameliorating the membrane quality,improving the properties of mixed liquor and optimizing the operational conditions of membrane separation.
