Demanganization of River Water


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.

The specific features of using organic cationic flocculants in surface water treatment


The specific features of using high-molecular cationic flocculants for the treatment of water from surface sources characterized by low color, medium turbidity and low organics are considered. On basis of theoretical provisions and experimental results the expediency of using these flocculants as basic chemicals and in combination with mineral flocculants are shown; the conditions of using them at the water treatment plants are determined.
