Brief introduction

Polyaluminium ferric chloride (PAFC) is a kind of inorganic polymer coagulant, which is made by coagulation and hydrolysis of aluminum salt and iron salt. According to the principle of synergism, a new type of high efficiency coagulant is prepared by adding iron ion or ferric oxide and other iron compounds.

It combines the advantages of aluminum salt and iron salt, improves the morphology of aluminum ion and iron ion, and greatly improves the degree of polymerization. The advantages of aluminum and iron coagulants for air flotation operation and improvement of coagulation performance of polyaluminium chloride; the purification effect of high turbidity water and low-temperature and low turbidity water is special *, without adding basic auxiliaries or other coagulants.
