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.
