Modernization of the Zelenogorsk Water Supply Station is a Stage of Realization of the Regional Program Pure Water
Summary
The following works have been done within the limits of modernization of the Zelenogorsk water supply station (St. Petersburg): reloading of high-rate filters with installation of the new drainage system TRITON improvement of water aeration system (enrichment with oxygen in a pan aerator), and automation of technological process. The technique of water treatment for manganese at the second stage of the process with the use of catalytic oxidation in pressure filters containing the three-layered quartz sand, pyrolusite, and anthracite media has been introduced. The quality of water treated at the Zelenogorsk water supply station after its modernization meets the requirements of the Russian and European standards at all points.

A review of achievements in water treatment with regard to deferrization and demanganation
Summary
To provide the population with drinking water, it is necessary that the quality of purified water meets the standard requirements. The absence of an appropriate water supply source or the use of drinking water with exceeding the maximum permissible concentrations of pollutants subsequently harms human health. Besides, a deterioration in the operation of water supply systems occurs as a result of corrosion, deposits and blockage of pipes. One of the major problems of groundwater treatment is the increased concentration of iron (Fe) and manganese (Mn). The existing methods of iron and manganese removal from water and the conditions of their application are described. In addition, a comparative analysis of the methods is carried out and promising areas in this area are considered. It has been established that all the existing methods of iron and manganese removal either have or require a filtration stage. The use of a catalytic layer of modified media in filters provides for achieving higher purification and filtration rates that will reduce the expenditures of water treatment plants and the cost of purified underground water.

The use of ozonation equipment for natural water treatment at the Far North
Summary
The results of many years developing, commissioning and maintaining water treatment plants with ozonation used for ferrous iron and manganese oxidation, elimination of both natural organics and organics of anthropogenic origin, showed the reliability and efficiency of Ozonia OZAT® ozone generators. Beginning from 2007 a number of plants with the use of ozonation equipment for northern surface (lake) water treatment have been commissioned. When designing and commissioning the plants the results of technological studies carried out were taken into consideration. It was found that the two-stage treatment technology with preliminary chemical clarification of water with the use of ozonation as a stage that ensured high quality of water was the most efficient.

Improving the technology of deironing and demanganation of the underground waters in Ulyanovsk
Summary
An improved design of two-stage technology of deironing and demanganation of underground waters with the use of floating polystyrene foam media at the Ulyanovsk water treatment facilities was suggested and tested. At the first stage the processes of aeration-degassing, contact filtration and filtration rate regulation of the second stage filters are carried out. It was established that manganese removal from the underground water of Arkhangelsk water intake can be carried out only by additional dosing 0.6–0.8 mg/l of 4–5% potassium permanganate solution before the filters of the second stage. In doing so the time of chemical being in contact with the filter media of the second stage can be reduced from 20 to 4–5 minutes.

Filtering materials for de-ironing and demanganation of underground waters: selection criteria, varieties, and application environment (a review)
Summary
To ensure uninterrupted and high-quality water supply of cities and populated areas, complying with the requirements of the regulatory documents and standards is mandatory. Violating the standards during water treatment leads to rapid wear of water supply systems, and also produces a negative impact on human health while consuming poor-quality drinking water. Reducing the concentration of iron and manganese in drinking water is one of the most important tasks in water treatment in a number of countries. Based on a review of literary sources, the main criteria for selecting a filter media are considered; types of filtering materials used for underground water de-ironing and demanganation, and the application environment are described. Anthracite and activated carbon are the optimal filtering materials for the operation of filters. These natural materials with the properties studied are available, and widely used in water treatment processes. The synthesis of new catalytic filtering materials is promising for iron and manganese removal from groundwater. The variety of materials will allow changing the characteristics and morphology depending on the purposes of water treatment.
