In the same way, a new type of high efficiency coagulant prepared by compounding aluminum ferric chloride with iron ion or ferric oxide with other iron-containing compounds is provided, which combines the advantages of aluminum salts and iron salts, The morphology has significantly improved, the degree of polymerization greatly improved, black. Polymeric aluminum ferric chloride is based on the PAC and PFS, to meet the market requirements, combined with the advantages of both to develop not only with the hydrolysis of PAC polluted read open, the handling of small turbidity water There is a high molecular weight with polymeric ferric sulphate. Poly aluminum chloride is yellow or light yellow in color, dark gray or dark brown in color, and has been widely used in the field of water treatment Technical Index Poly aluminum chloride (PAFC) is a mixture of aluminum salt and iron salt Condensation hydrolysis into an inorganic polymer coagulant, according to the principle of synergies, rapid settlement of new products. Take aluminum, iron coagulant each of the advantages of air flotation operations to improve the coagulant properties of polyaluminum chloride
