In the framework of the given article shall be considered a negative impact on microorganisms of ions of zinc, copper and Nickel concentrations in the incoming wastewater to the wastewater treatment facilities of the cities of the Lower Volga region is unacceptably high, which inevitably reduces the quality of the purified water at the indicated metals exceeding the output after biological treatment is more than 30 times). Further, in the proposed article, we describe the results of studies aimed at disposal and treatment of waste activated sludge. The first attempt to use the resulting after biological purification of waste as a secondary raw material for the adsorption material, which retrieves the designated heavy metal ions from wastewaters prior to biological treatment, which allows further the activated sludge fully interact with other ions without losing their functions. As a result, after the biological cycle treated water at the indicated metals, meets the relevant standards.

The calculation of technological and economic losses caused by emission of electrolysis hydrogen in the atmosphere is made. The flow of oxygen and air during the combustion gases and the amount of simple combustion is calculated. The ways of economically viable utilization of associated hydrogen would increase the level of environmental safety of the process are revealed. We consider the use of hydrogen produced during electrolysis of sodium hypochlorite solution to produce hot water for the needs of the enterprise. Proposes the use of snow in the territory of the water supply enterprise as a backup element for the implementation of resource-saving technologies for potable water.

Considered clean water in swimming pools, on nonionic and anionic surfactants with special adsorbents. Water purification pools plavatelnyx unique, first of all, because the water contains various types of pollution, which it is exposed. Most of these contaminants are introduced by the users of the swimming pool and they have to be removed or destroyed (bacteria, viruses, organic, sweat, hair, makeup, etc.). Treatment of swimming pool water is much more complicated because of the need to carry out her many times, than drinking water treatment, which is carried out one-time. Based on these studies, given technological solution to improve the efficiency of purification of circulating water in swimming pools, ensuring high environmental and economic performance of water treatment.

Problems of the treatment of highly mineralized water from surface sources. Today, more than 70% of rivers and lakes has lost its main function as sources of drinking water. An important problem is to find technological solutions that take into account the territorial features and allows you to create reliable purification of saline natural waters with minimal capital and operating costs. In the present paper presents the results of a study of the composition and properties of natural raw chocolate clay Altonaga field, studied its sorption properties.

The possibility of DynaDisc disc microfilter application for biological wastewater treatment was investigated. Possible operating modes of filer have been simulated:as a part of full biological treatment scheme and as an installation for wastewater posstreatment, with reagent treatment and without.The main conclusions of DynaDisc disc microfilter application have been made.

The technologies of getting energy from the unlimited sources render possible to build the energy-independent houses with the ecologically clean infrastructure in remote areas and to solve the problems of the energy supply of the already-existing objects. In Azerbaijan and in Russia the mission-oriented research is carried out as both countries have either traditional or alternative stored energy sources, and much work is in progress on the parallel development of modern technologies of energy providing of human life support including technologies based on the use of mineral waters which are of interest in the field of bioengineering resources. The primary chemical and thermophysical properties of mineral waters underlie in creation of the technologies of the use of their resources. The special investigations on the determination of chemical properties of mineral waters of separate regions of the Stavropol Territory of the Russian Federation are substantiated and assumed in the article. In the paper the experimental works of the chemical composition of nine mineral waters of the sources of the regions of Pyatigorsk and Yessentuki cities are carried out by the methods of experimental atomic emission spectroscopy and ion chromatography. The major part of the established chemical elements includes sodium (Na) (from 844 up to 6620 mg/liter); then calcium (Ca) as one of the main sources of cations, and also kalium (K) and magnesium (Mg) (they compose from 6.7 up to 92.2 and 15 up to 76.2 mg/liter correspondingly). Sulfur (S) is also important with the quantity of 362 mg/liter; silicon is in sufficient number as part of these mineral waters – from 3.5 up to 27.3 mg/liter. The small part includes lithium (Li), boracium (B) and strontium (Sr). The findings render possible to expand the world data base of the corresponding natural resources of the Russian Federation for the development of the ecologically oriented technologies.

The article highlights the issue of conservation of water and energy resources, the dependence of its decision on the environmental responsibility of business entities and tactical goals towards environmental management. Also the essence of the work carried out in the production of ammophos is described (Hydrometallurgical plant, Lermontov town), which is a good example of solving one of the many tactical tasks in the direction of environmental management. Specific purpose of the work was to identify the savings reserves of energy and natural resources. The application object of the study is the energy-intensive production of ammophos (fertilizer complex of nitrogen and phosphorus compounds), in particular the boiling-down of ammoniated pulp. The load decrease by evaporated water by 75% is achieved the implementation of technical solutions in terms of sealing pumps work (replacing inefficient crevice seal on a metal face seal) installed on the circulation line of ammoniated pulp. This reduces the coolant flow for boiling-down of high pressure steam and drinking water saving, which is the raw material for the production of fluid. Ecological and economic efficiency of the proposed solutions is confirmed by the calculation of the expected technical and economic parameters, performed on the basis of data generated in monitoring: coolant saving - 3039 Gcal / y; 2430 rubles / g; drinking water saving - 11,477 rubles.

The article discusses the possible causes of pollution of Taganrog Bay of the Azov Sea with oil products for the period 2008-2013. The key factors of pollution were highlighted. Effects of navigation for cotion was evaluated by navigation intensity. Effect of wastewater was evaluated by the number of oil products which fall from municipal drains and wastewater from industrial plants. The data processing of the federal statistical reporting on the influence of the main contamination factors was carried out.

The paper is devoted with the analysis of sources and volumes of oil components’ input into the Black sea. The topicality of this problem is connected with of transboundary the status of water object that contributes to the complexity of such works. Black Sea has important significance for transport and development in the coastal zone of the oil complex, combined with a great recreational potential. As a result, ecosystems are technogenic impact. The paper describes the main natural and anthropogenic sources of oil components in the Black Sea. On the basis of the results of our expeditionary research and analysis of sources of pollutant concluded chronic character oil pollution of the Black Sea. And the conclusion that the most optimistic estimates, entrance of oil components in the ecosystem in the Black Sea is approximately 270 thousand tons per year, which is higher than the currently accepted values of 2−2.5 times.
