In this paper, the effect of coagulation on membrane filtration resistance had been studied in the process of membrane filtration with dosing coagulants, analyzed the contribution of different membrane resistance in the membrane process, in order to find an effective way to control the membrane resistance. By Carman-Kozeny formula analyzed, voidage and deposited particle size of the composite cake is the greatest impact on the filtration resistance, and it is feasible that the composite cake resistance could be effectively controlled by selecting appropriate types of coagulant and controlling the dosage. Meanwhile optimization of membrane structure to decrease the membrane self-resistance could further reduce the total resistance in membrane filtration process, to improve the efficiency of drinking water membrane treatment.
