Article Preview

To further determine the effects of operational condition on water quality and to prepare a integrated unit for waterworks on a small or medium-sized in future, an experiment using Yangtze River source water(site in Zhenjiang) as raw water was carry out to run continuously for six months by applying the in-line microflocculation/sand filtration/ spiral UF membrane process. The results show that the coagulant dosage of 3~5 mg/L(as Fe), the sand filtration at a speed of 19.5m/h and the filtration flux at 1m3/m2.d can efficient in discharging the most suspensions, and a part of organics from water can de removed. The turbidity in sand-filtration treated water value of 3~10 NTU may cause little change in trans-membrane pressure difference and increase operating efficiency, while turbidity value is less than 2 NTU , much change is observed in the trans-membrane pressure difference. Although the wash pressure and membrane feed water quality have effect on the trans-membrane pressure difference, the wash pressure is not an important influencing the trans-membrane pressure difference.
