Basic information

Polyaluminum chloride is a kind of inorganic polymer coagulant, also referred to as poly aluminum, English abbreviation for PAC, due to the bridging effect of hydroxide ions and the polymerization of multivalent anions and the production of large molecular weight, high charge of inorganic polymer water treatment agent. In the form can be divided into solid and liquid two, and the solid according to the color is divided into brown, yellow and white, different colors of polyaluminum chloride in the application and production technology also have a big difference.
