Polyaluminum Chloride PAC 1327-41-9 for Drinking Water Treatment

Polyaluminum chloride (PAC),Water Treatment Agents Polyaluminum Chloride for Effective Removal of Contaminants in Drinking Water and Sewage

Polyaluminum chloride (PAC) is a water-soluble inorganic polymer between AlCl3 and Al (OH) 3, with a chemical formula of [Al2 (OH) nCl6-n] m, where m represents the degree of polymerization, n represents the neutrality of polyaluminum chloride products, and n=1-5 are high charge polymer chains with Keggin structure. PAC has a high degree of electrical neutralization and bridging effect on colloids and particles in water, and can strongly remove toxic substances and heavy metal ions. Its properties are stable, and it is often used as an emerging water purification material and coagulant, widely used in the purification treatment of drinking water, industrial wastewater, and urban sewage.
Polyaluminum chloride is divided into two types: for drinking water and industrial water, which are subject to different relevant standards. Its appearance color is yellow or light yellow, dark brown, and dark gray, and its form is divided into two types: liquid and solid. This product has strong bridging adsorption performance, and during the hydrolysis process, physical and chemical processes such as coagulation, adsorption, and precipitation occur. The fundamental difference between polyaluminum chloride and traditional inorganic coagulants is that traditional inorganic coagulants are low molecular weight crystalline salts, while polyaluminum chloride's structure is composed of multi carboxyl complex compounds with diverse forms. It has a fast flocculation and precipitation rate, a wide range of applicable pH values, and is non corrosive to pipeline equipment. Its water purification effect is obvious, and it can effectively remove color SS, COD, BOD, arsenic, mercury and other heavy metal ions in water. This product is widely used in the fields of drinking water, industrial water, and sewage treatment.
