Poly Aluminium Chloride (PAC)

Poly Aluminium Chloride (PAC) is a highly effective water purifier and coagulant. It is a water-soluble inorganic polymer that falls between ALCl3 and Al(OH)3. PAC typically appears as a yellow or light yellow, dark brown, or dark gray resinous solid. It is non-corrosive to pipeline equipment and offers significant water purification capabilities.

Description

Poly Aluminium Chloride (PAC) – Your Ultimate Chemical for Water Treatment and Drinking Water Solutions.

Poly Aluminium Chloride (PAC) is a highly effective coagulant widely used in water purification, industrial processes, and environmental management. South Chem Trading, a leading supplier in South Africa, offers high-quality PAC essential for water purification and sludge treatment. PAC is valued for its ability to remove impurities from water, providing a cost-effective and eco-friendly solution for modern industries.

Recently, the use of PAC has surged, as it is derived from aluminum chlorohydrate and has the chemical formula [Al2(OH)nCl6-n]m (CAS number 1327-41-9). One of PAC’s main advantages is its superior ability to remove suspended particles from water, thanks to its high charge destabilizing properties, making it more effective than traditional coagulants like aluminum sulfate.

PAC is available in two forms: solid powder and liquid, with the solid powder varying in color from white to light yellow, golden yellow, and brown. These color variations indicate differences in alumina content, affecting PAC’s effectiveness for specific applications.
