What is polyaluminium chloride?

Polyaluminium Chloride (PAC) is an inorganic polymer coagulant. It is a yellow solid powder that is widely used in water treatments. PAC is better than other aluminum salts such as aluminium chloride, aluminium sulphate, and other various forms of Polyaluminium chlorisulfate and Polyaluminium chloride that they have lower charge than PAC.

Who manufactures polyaluminum chloride?

USALCO ® has manufactured chemicals for over 60 years, and began full scale production of the patented process for manufacturing Polyaluminum Chloride in 1996.

Why is Pac better than other aluminum salts?

PAC is better than other aluminum salts such as aluminium chloride, aluminium sulphate, and other various forms of Polyaluminium chlorisulfate and Polyaluminium chloride that they have lower charge than PAC. Manufacturing Process

How long does polyaluminium chloride take to precipitate?

Stable PAC needs at least 9 weeks at 30o to precipitate. The presence of water during the process will be evaporated in the reactor that produces steam. Finally, Polyalumunium chloride contains more than 50% Al2O3. Polyaluminium chloride is used in the treatment of drinking portable water and wastewater treatment.
