ABSTRACT

Coagulation-ultrafiltration is the most common process based on membrane currently. It is characterized by its stable effluent quality, short retention time, strong shock resistance, compact package (Guan, Y.T. & Cao, P.F. 2010). However, for micro-polluted water used as the drinking water source, the organic pollutant removal capability of the conventional coagulation-ultrafiltration system is not satisfying. Preoxidation with

2.2 Experimental methods

Ultrafiltration experiments were conducted in a submerged hollow fiber membrane filtration system (Fig. 1). A mechanical stir at 20 rpm was employed to homogenize the solution in the reactor. Experiments were conducted in batch mode.
