%X An experiment was conducted to study the effect of bond extracellular polymeric substances (B-EPS) on the membrane fouling control property of a hybrid membrane bioreactor (HMBR). Results showed that the B-EPS, the loosely bond extracellular polymeric substances (LB-EPS) and the tightly bond extracellular polymeric substances (TB-EPS) in the HMBR decreased by 10.0%, 43.6% and 2.1%, respectively, comparing with the conventional membrane bioreactor (CMBR). The B-EPS had a significant correlation with the specific resistance to filtration of the cake layer, the lower the former was, the smaller the latter became. Otherwise, the LB-EPS affected the specific resistance to filtration of the cake layer more strongly than the TB-EPS. As a result, with the B-EPS especially the LB-EPS decreasing, the HMBR showed a good property of membrane fouling control and the cake layer resistance in which decreased by 56.9% comparing with the CMBR.
