Influence of Different Sizes of the PAC on TMP and Effluence in IMBR

In this study, the different sizes of the PAC are used to reduce transmembrane pressure (TMP) and prolong cycle of operation in IMBR (Integrate Membrane Biological Reactor). The ranges of size of the powdered activated carbon(PAC) are from 40-60 mesh, 80-100 mesh to 100-200 mesh. As a result, The PAC of 80-100 mesh can effectively reduce membrane fouling. And also, the carbon-slug ratio of 1:4 is best way to maintain the high membrane flux. In sum, the PAC is excellent anti-membrane fouling agent when the sanitary sewage is treated with IMBR.
