The objective of this paper was to investigate the practicability of coagulation-immersed membrane process during low-temperature period through the study of steady operation, chemical cleaning methods, water quality and agent consumption. Experimental results showed that: membrane performance decreases with the reduction of temperature, but low temperature has little effect on stable operation of immersed membrane when coagulation as pretreatment. EFM with 1200 mg/L sodium hypochlorite after every 48 filtration cycles was made for reducing membrane fouling efficiently, and the method, with 1. 5% sodium hydroxide and 3500 mg/L sodium hypochlorite for 10 h and then 2% hydrochloric acid for 4 h, is an appropriate cleaning method under low temperature. Compared with convention treatment process, immersed membrane process not only has same agent consumption, but also permeated water quality is more superior such as fine removal effect on turbidity with average 0. 10 NTU. Therefore, coagulation-immersed membrane process is more appropriate for increasing water quality demand and the treatment of low turbidity and low temperature water.
