What is poly Aluminium chloride (PAC)?

Poly Aluminium Chloride (PAC) is a highly efficient coagulant with the chemical formula [Al2(OH)nCl6-n]. It is widely used in water treatment processes to remove suspended solids, organic matter, and other contaminants. PAC is available in both liquid and powder forms and is known for its ability to perform effectively over a wide pH range.

What is poly aluminum chloride?

What is polyaluminium chloride used for?

Polyaluminium chloride is used as a primary coagulant in the treatment of drinking water. It is effective over a range of pH values. It is particularly effective on some waters and usually requires a lower dose than alum.

How effective is polyaluminium chloride?

Does polyaluminum chloride affect drinking water quality?

Residual chloride will be present, but at low levels that do not adversely affect drinking water quality. Polyaluminum chloride was endorsed by the NHMRC for use as a drinking water treatment chemical in 1979. The revision undertaken in 2003 did not change the status of this chemical for the treatment of drinking water.

When did polyaluminum chloride become a drinking water treatment chemical?

Polyaluminum chloride was endorsed by the NHMRC for use as a drinking water treatment chemical in 1979. The revision undertaken in 2003 did not change the status of this chemical for the treatment of drinking water.
