Extracellular polymeric substances (EPS) secreted from activated sludge are very important in a membrane bioreactor (MBR) in terms of filterability of activated sludge and membrane fouling. This study aimed to investigate the effect of SRT and micropollutants existence of wastewater in an MBR on EPS and soluble microbial products (SMP) of activated sludge. In the study, obtained results indicate that the EPS content and SMP concentration in the supernatant decreased with an increasing of SRT values from 15 days to 90 days. The results also indicated that the micropollutants existence of feed wastewater should affect the concentrations of EPS and SMP in submerged MBRs.
