Abstract：This study reported a novel strategy of integrating MFCs with a membrane bioreactor (MBR) for membrane fouling mitigation. The soluble microbial products (SMP) and extracellular polymeric substances (EPS) from the suspended sludge of MFC-MBR combined system and conventional MBR were analysed. Compared to the conventional MBR, the SMP and TB-EPS concentrations in the MFC-MBR combined system increased by 8.5% and 9.2% respectively. Conversely, the LB-EPS concentration decreased by 47.5%. In addition, the aromatic protein and humic acid in LB-EPS also decreased significantly. The membrane fouling was also investigated in the conventional MBR and MFC-MBR combined system .The time required to reach a TMP of 30 kPa was 38 days in the conventional MBR and 55 days in the MFC-MBR combined system, which indicated that the recycling of the sludge treated by MFC was able to alleviate membrane fouling.
