Polyaluminum Choride
Polyaluminum chloride (PAC) is an inorganic substance, a new water purification material and inorganic polymer coagulant, which is referred to as polyaluminum for short. It is a water-soluble inorganic polymer between AlCI3 and Al(OH)3.
FunctionThe flocculation of polyaluminium chloride is as follows:
A, strong electric neutralization of colloidal substances in water.
B. Excellent bridging adsorption of hydrolysate on suspended solids in water.
C, selective adsorption of soluble substances.
Polyaluminium chloride (PAC) is an inorganic polymer coagulant. The characteristics of inorganic polymer water treatment agent with larger molecular weight and higher charge, which is produced due to the bridging effect of hydroxide ions and the polymerization of polyvalent anions, are mainly determined by the working principle of pressure atomizer.
