Polyaluminium ChloridePAC

Polyaluminium Chloride (Polyaluminium Chloride) abbreviation PAC. Usually also known as alkaline aluminum chloride or coagulant, etc., it is between ALCL3 and AL (OH) 3, a water-soluble inorganic polymer, chemical test [AL2 (OH) NCL6-NLm] which m on behalf of the degree of polymerization, n represents the degree of neutrality of PAC products. The color is yellow or light yellow, dark brown, dark gray resin-like solid. The product has strong bridging and absorbing properties, and in the process of hydrolysis, it is accompanied by the occurrence of physicochemical processes such as coagulation, adsorption and precipitation.

The fundamental difference with the traditional inorganic coagulant is that the traditional inorganic coagulant is low molecular crystalline salt, while the structure of polymeric aluminum chloride consists of multiple carboxyl complexes with variable morphology, fast flocculation and sedimentation, wide range of applicable PH value, no corrosive to pipeline equipment, water purification effect is obvious, and it can effectively support the removal of color SS, COD, BOD and arsenic, mercury and other heavy metal ions in the water.
