PAFC is developed from the basis of an in-depth study of PAC and iron oxide, aluminum and iron salt coagulant hydrolysis and coagulation mechanism on which combines the advantages of aluminum and iron salts coagulation, of aluminum and iron ions form has improved significantly, the degree of polymerization is also greatly improve the appearance of: liquid product is brown or reddish-brown transparent body, no precipitation; the solid product is brown, reddish-brown powder or crystal form, very. Soluble in water.
