Study on Combined Process of Granulation and Coagulation for Strontium Removal

Article Preview

Abstract:

Optimization of coagulation conditions in the granulation-coagulation process for strontium removal was studied in this paper. The experimental results showed that the optimum coagulant was aluminum sulfate. The optimum coagulation conditions were dosage of 60 mg/L, coagulation time of 10 min, mixing speed of 180 r/min. The best combination method was granulation - coagulation - sedimentation. Under optimal conditions, the DF of strontium was 87 and the effluent turbidity was 1.05 NTU.
