What are polyaluminium chlorides?

Polyaluminium chlorides (PAC) are synthetic polymers dissolved in water. They react to form insoluble aluminium poly-hydroxides which precipitate in big volumetric flocs. These flocs absorb suspended pollutants in the water and can together be easily removed with the PAC.

What is poly Aluminium chloride?

Today, More and more companies focus on Poly aluminium chloride. It is a unique aluminum salt substance of aluminium chlorohydrate, and it is also simply called PAC. The general chemical formula is [Al2 (OH)nCl6-n]m (1≤n≤5 , m≤10). CAS No.: 1327-41-9.

Who makes polyaluminum chloride?

USALCO® has manufactured chemicals for over 60 years, and began full scale production of the patented process (US Patents 5,985,234; 5,997,838; 6,036,935 and Canadian Patent 2229266) for manufacturing Polyaluminum Chloride in 1996. USALCO manufactures a variety of Polyaluminum Chlorides to meet a wide range of water quality objectives.

Which PAC is the best recoagulant?

It is the best choice from aluminum sulfate, aluminium chloride to polyaluminium chloride PAC. The solid powdered PAC from us is made by excellent spray drying technology. It is used as a recoagulant in drinking water purification, as an antiperspirant in deodorants and flocculant in waste water treatment.

Is polyaluminium chloride dangerous?

Warning! Polyaluminium Chloride everyone must know can be hazardous, no explosives. The material is corrosive outdoors. if anybody attempts ingestion, Inhalation, or human skin contact, it may cause injury to body health. The researcher must evaluate the MSDS and TDS of PAC before using it.
