Biofouling is a serious and challenging problem in water treatmentsystems which hinder the efficiency of membrane filtrationperformance. The aim of this study was to investigate the biofoulingpropensity and biological treatment performance of a bacterialconsortium in a biological membrane bioreactor for the treatment ofdye wastewater. During bioreactor operation with the bacterialconsortium, a significant relationship was revealed betweentransmembrane pressure (TMP) and extracellular polymeric substances(EPS). When tested for dye and chemical oxygen demand (COD) removal,SMBR showed increased removal performance with the operating time,possibly owing to the biofilm formation on membrane and theadaptation of sludge. Thus, it is expected that the results of this studywill be valuable for further development of a suitable biofoulingmitigation strategy for batik wastewater treatment in membranebioreactor.Keywords: Biofouling; biofilm, Batik wastewater; bacterial consortium;extracellular polymeric substances
