Effect of mixed liquor volatile suspended solids on membrane Fouling during short and long-term operation of membrane bioreactor

The aim of this study was to examine the impact of different Mixed Liquor Volatile Suspended Solids (MLVSS) concentrations on membrane fouling, in a submerged Membrane Bioreactor (MBR) at short and long-term MBR operation for wastewater treatment -- Three laboratory-scale in a submerged MBR system w...
