Abstract
This research on reduction of membrane scouring aeration demand in membrane bioreactor was conducted using experimental fluid dynamics (EFD) and computational fluid dynamics (CFD). We evaluated the effect on motion ofPEG gel carrier in flow channel between flat membrane sheets, and confirmed that the motion of the carriers increase scouring perf ormance. In this research, analysis on the fluid flow field with CFD shows that uniform distributions of fluid vel ocity and its gradient are formed in the flow channels over all. Finally, we evaluated the reduction of scouring ae ration in the integrated Membrane Bioreactor applying carriers at the bench scale setup. The aeration demand is decreased by 50% with carriers in the evaluation test.
