Polyaluminum chloride (PAC) is a kind of inorganic polymer coagulant, the main raw materials hydrochloric acid, bauxite, calcium 

powder and other materials through a special process polymerization. The product color is yellow, dark brown granular solid, 

non-toxic and harmless. Through strong bridging adsorption, the physical and chemical reactions such as condensation, adsorption

 and precipitation occur in the hydrolysis process to achieve the effect of water purification. Features: high activity, strong adsorption

 capacity, large alum formation, fast flocculation and precipitation rate, large molecular structure, small dosage and low processing

 cost. It is non-corrosive to pipeline equipment, has obvious water purification effect, is less affected by water PH value and temperature, 

and has stronger adaptability.
