Inorganic polymer coagulant poly aluminium silicate sulfate(PASS) has been prepared by using sodium silicate and aluminum sulfate as rawmaterials. According to the 3-factor orthogonal test, the conditions of preparing PASS,which has better stability and good coagulating effect,are optimized:ω (SiO2<.sub>)=1%,pH=3 and copolymerization. Self-made PASS under optimum conditions is used in the pratical drinking water. The results show that PASS has better coagulating effect and lower residual aluminum content in treated water , compared with aluminum sulfate and PAC.
