Study on the Membrane Flux of Membrane Reactor and Fouling Control of PVA Membrane

Abstract:

Membrane is the key that restrict Membrane Bioreactor technology be extensive applied, the membrane flux is an important factor to measure membrane, membrane fouling is the main factor which result in the membrane flux low, the membrane fouling research on a new type of hydrophilic PVA membrane .The experiment results show that the membrane flux is high with the use of PVA membrane. The COD removal rate can reach 90% on average, with long time running, the flux has declined. The flux can be maintained at 168 L/m².h on the conditions that low-flux, intermittent effluent, backwashing, intermittent aeration, change of aeration intensity and physical cleaning. The membrane bioreactor using PVA membrane was efficient and stable in operation.
