- Characteristics:
Poly Aluminum Chloride(PAC) is commonly referred to as a water purifying agent or coagulant, it is a water-soluble inorganic high molecular polymer between ALCL3 and AL(OH)3, and has the chemical formula [AL2(OH)nCl6-nLm] m represents the degree of polymerization and n represents the degree of neutrality of the PAC product. For PAC solid form, the color is light yellow powder, milk white powder or dark brown grunale like sand shape.The product has strong bridging adsorption performance, and is accompanied by physical and chemical processes such as coagulation, adsorption and precipitation during the hydrolysis process. The fundamental difference between polyaluminum chloride and traditional inorganic coagulant is that the traditional inorganic coagulant is a low molecular crystalline salt, and the structure of the polyaluminum chloride is composed of a polymorphic multi-carboxy complex, which has a fast flocculation and precipitation. It has a wide range of PH values, is non-corrosive to pipeline equipment, and has obvious water purification effect. It can effectively remove heavy metal ions such as SS, COD, BOD and arsenic and mercury in water. This product is widely used in drinking water treatment, industrial water treatment and sewage treatment.
