Abstract

The reduction of the volume and footprint requirements of membrane bioreactors (MBR)s is constrained by the maximum amount of biomass that can be accommodated in the aerobic basin. However, the biomass concentration is mainly limited by the extremely low oxygen transfer efficiency (OTE) experienced by conventional aeration bubble diffuser systems at mixed liquor total suspended solids (MLSS) concentrations higher than 20 g L-1. Another potential limitation for the operation of MBRs at such high MLSS concentrations is the reduction on the membrane permeability due to excessive fouling...
