Enhanced biological phosphorus removal in membrane bioreactors

Water Science and Technology, 2002
Enhanced biological phosphorus removal (Bio-P) in a membrane bioreactor (MBR) promises several advantages but was never attempted as not compatible with high sludge ages. This article includes description and results of bench-scale investigations on Bio-P removal in an MBR.
