Study on the Flow Field in Membrane Bioreactor Research by using PIV

Membrane bioreactor flow field distribution directly affect effective control of the membrane pollution, and effectively determine the membrane flux. The experiments of membrane bioreactor liquid are measured by using PIV that the measurement areas include membrane bioreactor upper, middle and lower. The experimental data obtained velocity field information through the PIV software analysis. The experimental result indicates that middle of the membrane bioreactor flow field is the most unstable. The experimental measurement result provide membrane bioreactor structure the optimized design, effective control of membrane pollution and raise the membrane flux.
