Polyaluminium Chloride (short for PAC) is an inorganic polymer coagulant. It is a polymer water treatment agent with high molecular weight and high charge, which is produced by the bridging effect of hydroxyl and the polymerization of adding anions. The structure of Poly Aluminium Chloride (PAC) is composed of polycarboxylic acid complex in various forms, which has fast flocculation, precipitation speed, wide range of applicable PH value, non-corrosive to pipeline equipment, obvious water purification effect and effective in the removal of water color quality SS, COD, BOD and arsenic, mercury and other heavy metal ions. Based on this, Poly Aluminium Chloride (PAC) are widely used in drinking water, industrial water and wastewater treatment field.

Main Parameter:

Aluminum oxide/%: ≥29

Basicity %:40.0-90.0

Arsenic(As)/%: ≤0.0002

Lead(Pb)%:≤0.001

Cd(Cd)/%:≤0.00020

Hg(Hg)/%:≤0.00001

Water insoluble quanlity score/%: ≤0.6

PH Value: 3.5-5.0

Application:

1.It is mainly used for the purification of potable water

2.the treatment of industrial waste water and special water (such as oily sewage, printing and dyeing papermaking wastewater, sewage treatment, smelting sewage, radioactive substances, toxic heavy metals such as Pb and Cr, and fluorine-containing sewage,etc.)

3.It also use in precision cast, paper production

4. Drilling, tanning, metallurgy, papermaking and other industries.

Poly aluminium Chloride (PAC) is yellow or light yellow, dark brown, dark gray resinous solid. It has a strong bridged adsorption property. During hydrolysis, condensation, adsorption, precipitation and other physical and chemical processes occur.
