Influence of Aeration and Biomass Concentration on Critical Flux Enhancement

Abstract

In the present study, the effect of operational parameters on critical flux values was investigated including different aeration and different MLSS concentration.  Experiments were carried out on a pilot-scale membrane bioreactor (MBR) treated wastewater.  The results indicated that an increase of air sparging rate is very effective on enhancing critical flux, while high biomass concentration influenced in the greater fouling phenomena, resulting in lower critical flux.
