Sewage-grade polyaluminum chloride is an inorganic polymer flocculant , which is a high-molecular-weight , high-charged inorganic polymer water treatment agent due to the bridging action of hydroxide ions and the polymerization of polyvalent anions. The molecular formula is [AL2(OH)nCL6-n]m (n is 1-5 m<=10). Base degree: B = n / 6 × 100%. Its coagulation effect is as follows: 1. Strong electrical neutralization of colloidal substances in water. 2. Excellent bridging adsorption of hydrolysate on suspended solids in water. 3. Selective adsorption of dissolved substances.
