Application of polyaluminium chloride in water treatment

Polyaluminum chloride is a new water purification material, inorganic polymer coagulant, poly aluminum chloride, PAC(Poly aluminum chloride), it is between AlCI3 and Al(OH)3, a water-soluble inorganic polymer, The chemical general formula is [Al2(OH) Ncl6-NLM], where M represents the degree of polymerization and N represents the degree of neutrality of PAC products. In m product, n=1-5 is a high charge polymeric ring chain with Keggin structure, which has high electrical neutralization and bridging effect on colloid and particulate matter in water, and can remove microtoxic and heavy metal ions with strong strength, and has stable properties. Inspection method can be in accordance with the international GB 15892-2003 standard inspection. Due to the bridging action of hydroxide ions and polymerization of polyvalent anions, polyaluminum chloride is an inorganic polymer water treatment agent with higher relative molecular weight and charge.
