A novel microbial fuel cell (MFC) – membrane bioreactor (MBR) integrated process was designed based on the combination of MBR and MFC for the membrane fouling control conducted by the electric field generated from MFC in wastewater treatment. The performances of the integrated process under different operational conditions were investigated and compared with conventional MBR. The results showed that the electric field generated by MFC was conductive to mitigate membrane fouling and prolong membrane filtration interval by controlling the growth of irreversible fouling resistance in the membrane filtration. The electric field had a significant advantage on the suppression of carbohydrate of small formula weight in LB-EPS under various MLSS
while compared with LB-EPS
the concentration of TB-EPS had no significantly change. Under appending electric field
the absolute value of zeta potential was decreased by 2.7
7.1 and 4.1 mV
respectively
the growth of filamentous bacteria was promoted
and the larger sludge particles were generated through the improved floc aggregation.
