Experimental Study on Water Purification by Combination Processes of KMnO₄ Pre-Oxidation and Flotation-Sedimentation Tank

Abstract:

Low temperature and low turbidity surface water is difficult to be treated using the traditional water treatment process, especially microamount organic matter and odor compounds in the water is hardly to be removed. The aim of this paper was to study the removal effects of treating reservoir water derived from Yellow River by combination processes of KMnO₄ pre-oxidation and flotation-sedimentation tank. The results showed that the best dosage of KMnO₄ was 0.3mg/L and removal efficiency of COD_Mn, UV₂₅₄ and turbidity after KMnO₄ pre-oxidation was 20.52%, 20.17% and 13.88%, especially. The combination processes have the advantage of treating the surface water at low temperature and low turbidity
