Polyaluminium Chloride
Polyaluminium chloride (PAC) is a water-soluble inorganic high molecular polymer. General chemical formula: [AL2(OH)NCL6-NLm]. It is yellow, light yelow, dark brown or dark grey resin-like solid. It has strong absorption property.
PAC features fast flocculating rate, wide applicable pH range; non-corrosion to pipes and equipments and excellent water purifying effect. It is widely used in drinking water, industrial water and sewage disposal areas.
