【Abstract】 A new raw material--calcium aluminate was used to prepare the polymeric aluminum ferric chloride(PAFC).The optimum preparing factors were determined and the effect of the flocculant was studied with jar test. The experimental results show that the flocculent effect of PAFC may be affected by the basicity and the value of pH. PAFC has a best flocculent effect at the basicity of about 75% and the value of pH 7～9.更多还原
