Abstract
Ultrafiltration of B reservoir(near Harbin in China) water was studied to produce drinking water as a possible alternative treatment to conventional clarification.Water temperature,turbidity,operation pressure and coagulant dosage were investigated how to affect the membrane performance.There is a somehow linear relationship between membrane flux and ln turbidity of feed water.Using coagulation before UF increases permeate flux.Ultrafiltration is a pressure-driven process.Permeate flux increase with increasing the trensmembrane pressure.Chemical analyses of the permeate water showed that drinking water regulations were fulfilled.UF treatment provided effective turbidity removal.Iron,manganese and aluminum were removed completely.UF membrane also perfectly removes all coliform bacteria.The reduction of total organic carbon was satisfactory.
