| Abstract: | In order to reduce the turbidity and aluminum ion of Changjiang river, a novel coagulant has been presented in this paper, which is called PCMS. And the proportion of this coagulant is V（0.1wt% PAFC）：V（0.001wt% CTS）： V （3wt% MS） = 25：5：7. Operational conditions of neutral pH and room temperature allow up to 98% turbidity and 67.3% aluminum ion removal with 5 mg-L-1 of coagulant. Stirring intensity and mixing periods, temperature and pH are evaluated and they are found to be less influential than coagulant dosage. Compared with the single classical coagulant, PCMS is more efficient than PAC, PFS and aluminum sulphate and so on. |
