The study of turbid substance removal in water by hydrated manganese dioxide

摘要

The turbid removal experiments were conducted with hydrated manganese dioxide that produced by deoxidization of KMnO4 for simulated water and Tiansha River water. And the factors that influence the coagulation and the effects of coagulation were analyzed in this study. The results showed that hydrated manganese dioxide was one kind of effective water treatment agent which has significant removal effect of turbid in water. The turbidity in Tiansha River water can be removed more than 95% with the addition of 13 mg/l of hydrated manganese dioxide in tests.
