Polyaluminum Chloride is yellow or light yellow solid powder, soluble in water and has relatively strong bridging and absorption functions. In the hydrolysis process, there are some physicochemical changes such as electrochemistry,coagulation, adsorption, precipitation and so on, finally
form [AL2(OH)3(OH)3] ∞, therefore reach the purpose of purification.
According to the national standard GB15892-2003 ( type A used for drinking water, type B used for industrial
