Effect of varying SRT on the performance of MDBR

Membrane fouling has always been a challenge in membrane systems. Several parameters affect fouling, but extracellular polymeric substances (EPS) has often been reported as the major foulant. Sludge retention time (SRT) has been known to affect the biochemical characteristics of biomass that are res...
