Properties

1.Polyaluminium chloride/PAC, is effective primary inorganic coagulant based on Al3+, excellent for drinking water production, wastewater treatment, as well as swimming pool treatment.

2.Through the hydroxyl ion bridging function and the polyvalent anion polymeric function, it produces large molecular and high electricity inorganic macromolecule, brings higher performance than traditional coagulants.

3.Wide applicable range of pH value, and good performance in low temperature.

Usage for poly aluminium chloride pac

1.Water treatment: domestic water, industrial water;

2.Urban sewage treatment;

3.Treatment of industrial wastewater, sewage, sludge and some slag recovery in sewage;

4.For some industrial wastewaters that are difficult to handle, PAC is used as the parent, and other chemicals are blended into a compound PAC. The treatment of sewage can be surprisingly effective.
