Description
PAC poly aluminium chloride, poly aluminium for short,commonly known as water purifier, is a kind of cationic inorganic polymer flocculant with hydroxyl and nuclear complex body, poly aluminium chloride coagulant. Its appearance of solid product is yellow or white solid powder, and the chemical formula is AL2 (OH) nCL6-nm(1≤n≤5,m≤10). It is soluble in water, and has the strong adsorption.In the process of hydrolysis, t finally turns to AL2(OH)3(OH)3 to achieve the purpose of purifying water, after a series of reactions:electrochemical, coagulation, adsorption and precipitation.
