Abstract：

Reservoir water from the Yellow River Liujiaxia Reservoir has the characteristics of low temperature、low turbidity and excellent water quality, it is conducive to using ultrafiltration water treatment technology to provide high quality drinking water. This research has comparative studied on the treatment effect and membrane fouling of ultrafiltration (UF) and coagulation-ultrafiltration (coagulation-UF) for reservoir water from the Yellow River LiujiaxiaReservoir. The experimental results show that: there is little difference betweenUF and coagulation-UF on membrane effluent turbidity, constant less than 0.2 NTU;When the dosage of ferric chloride is 35 mg/L, coagulation-UF on the removal rate of UV254reached 56.25%~80%, while UF only reached 7.84%~27.50%;When the membrane flux tends to be stable, the relative flux of the coagulation-UF membrane is 1.86 times that of UF; Coagulation process can effectively reduce the pollution of filter cake layer and adsorption. Compared with UF, aeration cleaning、hydraulic backwash and ultrasonic cleaning effect is better for coagulation-UF filtration membrane.
