将活性聚硅酸与聚合硫酸铁铝按照一定比例复合，经熟化，即制得新型无机高分子混凝剂PFASS。
The inorganic high molecule coagulant of PFASS is synthesized with the poly-silicic acid into the solution of polymeric ferric aluminum sulfate.
结果表明，硫酸铁的除砷效果优于铁铝聚合物和聚硅酸金属盐混凝剂；
The results showed that the arsenic removal with ferric sulfate was better than that with ferric aluminum copolymer and polysilicon metal salt.
PAFS的絮凝效果优于市售的聚合氯化铝和高效复合铝铁。
The flocculent effect of PAFS is superior to that of polymeric aluminum chloride and composite aluminum ferric in market.
