Abstract:
The process for preparation of a novel inorganic composite coagulant from coal ash and red mud has been studied. The results of flocculating effect tests in comparison with polyaluminum chloride(PAC) and alunite show that the new coagulant has better flocculation performance, and lower residual aluminum than alunite.
