Deironing-demanganation of ground waters at the Severny intake facilities of Khanty-Mansiysk
Summary
The results of investigating the process of deironing-demanganation of ground waters at the Severny intake facilities of Khanty-Mansiysk are presented. Ground water subject to treatment is characterized by low hardness, low alkalinity, low salt concentration and temperature values typical for the waters in the north of Tyumen. The water treatment technology applied at the intake facilities does not ensure meeting the water quality standards for iron and manganese. An alternative method of oxidation with potassium permanganate is suggested. As a result of the pilot tests at the Severny intake facilities the optimal dose of potassium permanganate that provided for decreasing iron and manganese concentration to the standard level was determined. It was shown that preliminary alkalization of the treated water to pH 7.5 and 8.5 allows 3–10 decrease of the dose.
