poly aluminium chloride

Poly-aluminium Chloride (PAC): Poly-aluminium Chloride, short for PAC, is a new type of high performance inorganic macromolecule flocculating agent. It's hydrolysis product of AlCl 3 and Al(OH)3 , and polymerized & bridged through hydroxyl group.

And its molecular formula is [Al2(OH)n Cl6 -n · xH2O] m (m ≤ 10,n=1-5)The Poly-aluminium Chloride is completely soluble into water, and has quite strong adsorption, many physic & chemical reaction, such as sedimentation, adsorption, agglutination, and electric chemistry, happen during hydrolysis process.

This product is mainly used in purify of drinking water and treatment of industry waste water, such as the radioactive material, leady (Pb++) chromate (Cr+++) high toxicity heavy metal and fluoride (F) waste water. Furthermore, it also widely used in precision casting, papermaking, tanning and some other fields.
