The fouling phenomenon in membrane bioreactors: model description and strategies for energy saving

2015

Membrane fouling represents one of the major crucial issues for membrane bioreactor (MBR). Membrane fouling and high aeration requirements (for inducing shear stress to limit fouling) make MBR operation economically demanding due to high energy costs. Although several studies on MBR fouling have been performed, a comprehensive knowledge on how to reduce membrane fouling and consequently energy saving is still lacking. Two scenarios are analyzed and compared each implementing different operating conditions. As expected, MBR operation at low air flow rate (qa) leads to a substantial reduction of the operational costs (namely, 20% respect to the suggested manufacturers ones in terms of qa).

The fouling phenomenon in membrane bioreactors: Assessment of different strategies for energy saving

2013

Abstract Membrane fouling represents one of the major issues for a membrane bioreactor (MBR). Membrane fouling and high aeration requirements (for inducing shear stress to limit fouling) make MBR operation economically demanding due to high energy costs. Although several studies on MBR fouling have been performed, comprehensive knowledge on how to reduce membrane fouling and consequently save energy is still lacking. An integrated mathematical model for MBR is applied to a University of Cape Town membrane bioreactor with the final aim to reduce the energy costs. In particular, the influence of the aeration intensity, the duration of filtration/backwashing cycles, and the number of membrane …
