Product Description
Polyaluminium chloride (PAC) is a water-soluble inorganic polymer coagulant with a CAS number of 1327-41-9. This product has strong bridging adsorption properties and will undergo physical and chemical processes such as coagulation, adsorption and precipitation during water treatment.
The difference between polyaluminium chloride and traditional inorganic coagulants is that traditional inorganic coagulants are low molecular crystalline salts, while the structure of polyaluminium chloride is composed of various forms of polycarboxyl complexes.
It has a fast flocculation and precipitation speed, a wide range of applicable pH values, no corrosion to pipeline equipment, and a significant water purification effect. It can effectively remove SS, COD, BOD, and heavy metal ions such as arsenic and mercury in water. This product is widely used in drinking water, industrial water and sewage treatment.
