Air sparging

Fouling remains a major issue for all membrane applications. This study investigated anti-fouling applications for a side-stream membrane bioreactor (MBR) fed with glucose-based synthetic wastewater. Air sparging, backflushing and high cross flow velocity (CFV) were investigated as anti-fouling stra

Membrane bioreactors (MBR) combine biological processes with membrane filtration. The main obstacle to efficient operation remains the deterioration of membrane permeability with time. One possible approach to the fouling issue is sub-critical flux operation. Other options are air sparging and backf

Air sparging has shown to be very efficient for flux enhancement in different membrane processes and for different membrane geometries. This study focuses on the application of air sparging to nanofiltration flat sheet membranes and aims to understand which hydrodynamic parameter is responsible for
