【Abstract】 The coagulation performance of polyaluminium silicate sulfate （PASS） a nd the amount of residual aluminum were researched. The effects of SiO₂/Al, curing time, stirring time, and pH on coagulability and residual al uminum were investigated. Experimental results show that the coagulation performance of PASS is better than aluminum sulfate, and the residual alumin um is lower. The favorable properties of PASS increase with the increasing of SiO₂/Al mole ratio. In addition, the source of residual aluminum and its decreasing methods were discussed.更多还原
