The potential of enhancing As(III) removal was investigated in a pilot study for the process of oxidation, precipitation and direct sand filtration as pretreatment before ultrafiltration. The pretreatment effectively facilitated As(III) removal and residual arsenic was below 10 µg/L for membrane eff

Surface water was purified by ultrafiltration membrane to produce drinking water. The membrane flux decreases with increasing turbidity and there is a somehow linear relationship between membrane flux and the log of turbidity. Mathematical model was built to predict the membrane flux based on this.

Ultrafiltration of Binxian reservoir (near Harbin in China) water to produce drinking water was investigated in this study. Membrane flux declined with temperature coming down. Using coagulation before UF not only increases the permeate flux, but also retards the permeability decline. In comparison
