Abstract：

A pilot-scale low pressure ultrafiltration membrane system was used to treat the finished water from a sedimention tank in the waterworks, and membrane fouling control was investigated. Physical backwashing, chemical enhanced backwash (CEB), chemical cleaning and pre-chlorination were studied for membrane fouling control. Results showed that physical backwashing have a little effect on fouling control, however, CEB, an online cleaning mode could have a great effect on fouling control, and the average recovery rate of specific flux was 85%. The effect of chemical cleaning with oxalic acid was better, after cleaning, the average SF value was increased to 265 L/(h•m2•bar). Pre-chlorination could slow down the fouling rate. In addition, the composition of the eluent was analysed. The results revealed that iron and dissolved organic matter were the major factors for fouling.
