Polyaluminium chloride is referred to as PAC. Usually also known as basic aluminum chloride or coagulant, it is a water-soluble inorganic polymer between ALCL3 and AL (OH) 3, the chemical formula is [AL2 (OH) NCL6-NLm] where m represents the degree of polymerization and n represents the degree of neutrality of PAC products. The color is yellow or yellowish, dark brown, dark gray resinous solid. The product has strong bridging and suction performance, and in the hydrolysis process, it is accompanied by physical and chemical processes such as agglomeration, adsorption and precipitation.

This product is a water-soluble polymer. Because its molecular chain contains a certain number of polar groups, it can bridge between particles by adsorbing solid particles suspended in water or condense particles to form large flocs through charge neutralization. Therefore, it can accelerate the sedimentation of particles in the suspension, and has a very obvious effect of accelerating the clarification of the solution and promoting filtration.
