Properties of polyaluminium chloride
1.Wide range of application and wide adaptability to water.
2.It is easy to form large alum flowers quickly and has good precipitability.
3.The water quality after purification is better than inorganic coagulant suchas aluminum sulfate, and the cost of water purification is 15-30% lower than that.
