A process for preparing liquid polyaluminium chloride coagulant is introduced.It uses kaolin as raw material
which is pretreated
and then roasted
soaked in hydrochloric acid
filtrated
concentrated
mixed for polymerization and finally adjusted for pH.We optimize the process by means of orthogonal text method.The results show that the order of influence degree of the product quality from big to small is: acid-dissolution feedstock ratio
the proportion of pretreated with hydrochloric acid
