Coagulants

PAC (CAS No. 1327-41-9,for Industrial Effluent)

 

This product is a new-type inorganic macromolecule coagulant with high efficiency. It is widely used in the industrial wastewater purification.

 

Properties

  • Superior quality polyaluminium chloride (PAC). The water treatment cost is 20%-80% lower than that of other inorganic flocculants.
  • Highly efficient coagulant. It can lead quick formation of flocs with big size and rapid precipitation.
  • It has wide-range adaptability to the waters at different temperatures and a good solubility.
