Polyaluminium Chloride (PAC) 28%

 

PAC is a water-soluble inorganic polymer flocculant. In the hydrolytic process, it is accompanied with the chemical processes such as electrochemistry, coagulation, absorption and precipitation. PAC has the features including wide applicable range of PH value, large granule and quick speed in sedimentation. It is widely applied for treating the drinking water, industrial water and daily sewage.
