Polyaluminium chloride/PAC
PAC is a kind of inorganic polymer coagulant,the color is yellow or pale yellow,dark brown,dark gray resin solid. It is effective primary inorganic coagulant based on Al3+, used in drinking water production, sewage treatment and swimming pool treatment.
Through the hydroxyl ion bridging and the polyvalent anion polymeric effect, it produces large molecular and high electricity inorganic macromolecule, brings higher performance than traditional coagulants. PAC have wide applicable range of PH value and good performance in low temperature.
