Poly aluminum chloride (Polyaluminium Chloride) referred to as PAC. Usually also known as alkali aluminum chloride coagulant and so on, it is somewhere between ALCL3 and AL (OH) 3 between a water-soluble inorganic polymers, chemical formula [AL2 (OH) NCL6-NLm] where m represents the degree of polymerization, n is the PAC level of neutral products. Color is yellow or pale yellow with dark brown, dark gray resin solids. Bridge of the product has strong adsorption properties, in the hydrolysis process, accompanied by cohesion, physical and chemical processes such as adsorption and precipitation.
Poly aluminum chloride is an inorganic polymer coagulant. By compressing double major, Desi neutralization, adsorption bridge, the sediment mechanism such as netting, make subtle destabilization of suspended particles and colloidal ions in water, aggregation, coagulation, flocculation, sedimentation, purifying effect. The products compared with other coagulants, has the following advantages: l, wide application range, adapted to water a wide range. 2, easy to quickly form of alum, sedimentation good performance. 3, suitable for a wide range of PH values (5-9), and the water has a PH value and alkalinity decreased after small. 4, when the water temperature is low, can still maintain stability sedimentation effects. 5, alkalization degree than other aluminum salts, ferric salts high erosion of equipment small.
