5. POTASSIUM PERMANGANATE Potassium permanganate (KMnO4) is used primarily to control taste and odors‚ remove color‚ control biological growth in treatment plants‚ and remove iron and manganese. In a secondary role‚ potassium permanganate may be useful in controlling the formation of THMs and other DBPs by oxidizing precursors and reducing the demand for other disinfectants (Hazen and Sawyer‚ 1992). The mechanism of reduced DBPs may be as simple as moving the point of chlorine application further
