The flocculation of PAC is as follows:
A.Strong neutralization of colloidal substances in water.
B.Excellent bridging adsorption of hydrolysates on suspended solids in water.
C.Selective adsorption of soluble substances.
Polyaluminium chloride is a kind of inorganic high polymer coagulant.The characteristics of inorganic high polymer water treatment agent with high molecular weight and high charge, which is produced due to the bridging effect of hydroxyl ion and the polymerization effect of multivalent anion, are mainly determined by the working principle of pressure atomizer.
