Polyaluminium chloride is a kind of inorganic polymer coagulant,the color is yellow or pale yellow,dark brown,dark gray resin solid. It is formed by hydroxylions of bridging function and the order of anionic polymerization,the molecular weight and charge density is higner,the flocculation body forming fast,the applicable range of value is5-9.
It is widely applied in water purification, wastewater treatment, precision cast, paper production, pharmaceutical industry and daily chemicals
