PolyAluminium Chloride (PAC)

CAS No.: 1327-41-9   

Molecular Formula:  [Al2(OH)nCl6-n]m ; m,n 1-5, m≦10

 

Property:

PAC is high-effective inorganic polymer coagulant. It is widely applied in water purification, wastewater treatment, precision cast, paper production, pharmaceutical industry and daily chemicals. Its dosage lower than aluminum sulfate (based on Al2O3) and water treatment cost is lower than other inorganic flocculants. PAC can cause quick formation of flocculates, big flocculates formation and rapid precipitation. Its treatment capacity is 1.3-3.0 times of other inorganic flocculants. The PAC enjoys wide-range adaptability for different-temperature source water and a good solubility. PAC is slightly corrosive and easy for operation, and it is suitable for automatic dosing. Furthermore, it will not block pipes over long-time usage.
