English Name: polyaluminium chloride (water purifying agent)
CAS No.: 101707-17-9
Molecular formula: Al2Cl(OH)5
EINECS No.: 215-477-2
Overview: polyaluminium chloride, referred to as PAC, is an inorganic polymer coagulant. It is an inorganic polymer water treatment agent with large molecular weight and high charge produced due to the bridging effect of hydroxyl ions and the polymerization of multivalent anions. Solid products have the advantages of high adsorption activity, short sediment clarification time, wide pH range, no coagulant aid and no influence of water temperature. They are widely used in water purification treatment of domestic water and industrial water, urban sewage treatment, industrial wastewater, sewage, sludge treatment and some residue recovery in sewage. At the same time, PAC is taken as the matrix for some industrial sewage with great treatment difficulty, Mixed with other agents and formulated into composite PAC, sewage treatment can get a surprising effect.
