Performance evaluation of attached growth membrane bioreactor for treating polluted surface water.

Attached growth membrane bioreactor (aMBR) process was investigated for treating polluted surface water with COD around 10mg/L of raw water. Lab scale reactors, aMBR with 15% PVA-gel as carrier and conventional membrane filtration reactor (MF) were tested in parallel. aMBR achieved two times higher COD removal than MF system.
