CFD model of an airlift membrane bioreactor (MBR) module was built to determine the air dispersion within the membrane module. This model was extrapolated from a single membrane tube model where the resistance due to bundle of tubes and to the membrane were made to mimic the operation of a real airlift MBR module. Two types of air diffusers were tested (ring and disk aerator) to observe the air distribution within the membrane module. The disk aerator was found to provide a better air distribution in the module which implies better mixing and decrease in fouling at the membrane wall due to the better two-phase cross flow.
