Polyaluminium chloride is a kind of water purification material, inorganic polymer coagulant, also known as polyaluminium, abbreviated as PAC in English. Because of the bridging effect of hydroxide ion and the polyvalent anion, the inorganic polymer water treatment agent with higher molecular weight and charge is produced. Morphologically, it can be divided into solid and liquid. Solids can be divided into brown, beige, golden and white according to their colours. Liquids can be colorless, transparent, yellowish, light yellow to yellowish brown. Different colours of polyaluminium chloride have great differences in application and production technology.

Effect

A. Strong electric neutralization of colloidal substances in water.

B. Excellent bridging adsorption of suspended solids in water by hydrolysates.

C. Selective adsorption of soluble substances.

Polyaluminium chloride is a kind of inorganic polymer coagulant. The characteristics of inorganic polymer water treatment agents with high molecular weight and high charge are mainly determined by the working principle of pressure atomizer because of the bridging effect of hydroxide ion and the polyvalent anion polymerization.
