title: [Determining factors on the steady operation of immersed membrane process].
abstract: Target at the steady operation state, a pilot-scale test on the treatment of Luanhe source water was carried out using the process of coagulation-immersed membrane. The effect of membrane flux and water making period and raw water quality was systematically studied by means of trans-membrane pressure (TMP). The results show that the coagulation-immersed membrane process can control membrane fouling better and keep a steady operation state when membrane flux is 53.3 L/(m2 x h) and water producing period is 30 min. Water temperature change is one of the important factors, and the TMP of each filtration period can increase 76% from high temperature to low temperature raw water. Enhanced flux maintenance (EFM) integrated with chemical clean is a good control measure of membrane fouling.
