| Abstract: | A method of manufacturing polyaluminum sulfate with aluminum sulfate was introduced.In order to increase flocculating effectiveness and aluminum concentration,several alkaline substances were selected and the effect of B on aluminum configuration was studied.Flocculating effectiveness of AS,PAC and PAS was studied by coagulation test.The residual aluminum of AS,PAC and PAS in treated water were examined.The experimental results show that the Al a of PAS is less than PAC's,the Al b of PAS is approximate to PAC's and the Al c of PAS is more than PAC's under identical B.PAS has wide pH range,good subsidence performance and low residual aluminum. |
