Demanganization of River Water

Summary

One of the intractable problems of public utilities for treatment of water from surface sources, an impossibility of water demanganization using the classical scheme of water treatment, is considered. The results of studies of river water aftertreatment for manganese with the help of potassium permanganate at the water supply facilities of the city of Pugachev, Saratov Reg., are presented. In the course of selection of the method of reducing the manganese content the pH value and redox potential of the medium are taken into account. The studies conducted and the testing operation of the system of potassium permanganate dozing show that the treatment using this reagent ensures the residual content of manganese in potable water meeting the specified requirements.
