Global and Regional Control of Water Quality

Summary

There is a review of provisions of international agreements in the field of control of water objects: potable water supply sources, the existing system of the state control of water quality on the interstate (global) and state (regional) levels. The necessity of establishment of a legal order of regulation of water relations at the inter-regional level is noted. Performance of global and regional monitoring of conditions of the sources of potable water supply should bear an inter-agency character and should be realized within the bounds of basin agreements. These agreements should be mutually beneficial for all participating parties and based on the international principles of cooperation.

Key words

Problems of Development of the Water Industry for Providing the Population of Russia with Pure Water

Summary

The water industry is the most important factor in modernization of the economy and development of not only large but also small cities and settlements. The development of housing and communal complex, oriented on the provision of the guaranteed access of the population to potable water of high quality is considered as a task of national significance. The decision of problems of the water industry requires highly qualified staff. Investing in training them is the most important and well paid back part of investments. Russia can and should become one of the world leaders in the sphere of rational water use, application of innovative technologies in practice, the complete provision of the population with pure potable water. For this it is necessary to unite the efforts of the professional community, state and local authorities.

Intensification of resource-saving technologies of water use
in the industrial wastewater treatment

Summary

The results of research focused on improving the technologies and equipment of recycling water supply systems with plating wastewater treatment at the local treatment facilities using multi-chamber electrocoagulation devices are presented. The research objective was intensifying the resource-saving water use technologies by improving the circulating systems of technological galvanic processes at the industrial enterprises using multi-chamber devices based on electrochemical coagulation. The process solutions for industrial wastewater treatment using multi-chamber horizontal and vertical devices based on electrochemical coagulation are considered. The equipment productivity 6–8 m3/h provides for processing plating wastewater containing different concentrations of heavy metal ions, suspended substances, lubricants, oil products, etc. The obtained results confirm their practical focus that consists in increasing the efficiency of industrial plating wastewater treatment (of about 94–96%).

Directions for the development of the personnel training process for the water use engineering systems

Summary

The aspects of the personnel training system for water use engineering systems are considered. An analysis of the curricula structures in training professionals for the design, construction and operation of water engineering systems was carried out, on the basis of which approaches to improving the directions of training were presented. New promising directions for training specialists for the water supply and wastewater disposal sector are shown that provide for developing profiles that meet current industry requirements for practically oriented training of students for the operation of water management engineering systems to design the process technology and automation.

Sanitary and epidemiological situation in the Lower Volga Region: problems and solutions

Summary

Almost along the entire length from Tver to Astrakhan, the Volga River has been a depleted water reservoir in terms of its qualitative composition. In the Lower Volga basin the resource of ecologically clean water is less than 3% of the total surface water resources of the Astrakhan Region. In this regard, drinking water quality problems in the Astrakhan Region have been caused by natural water pollution, poor water treatment at the waterworks, secondary pollution in the distribution networks. The ecological state of the Lower Volga has been analyzed, and its impact on the quality of drinking water supply has been estimated. The technologies of water purification used in the Astrakhan Region for water supply were designed and implemented in the 1960s–70s; they were not designed for the pollution load in terms of the quality and quantity significantly different from the current situation. An analysis of the operation of water intake and water treatment facilities was carried out that showed their extremely unsatisfactory technical condition and obsolescence. The ways of solving the problems of improving the quality of drinking water supply with account of the current critical ecological situation in the Lower Volga Region and world experience, are proposed.

Environmental priorities in providing water supply of Khabarovsk

Summary

Far-reaching activities on the water supply reorientation from the surface to ground sources in Khabarovsk are reported. For this purpose a water intake, water treatment facilities, pumping stations and water mains for Tungus deposit water abstraction and transportation are being constructed. The analysis of the available data shows an insignificant environmental impact of the given business activities. The construction of a ground water intake structure will not affect significantly the local flora and fauna. Here and there facilities will be provided for the formation of anthropogenically modified landscapes with improved environmental quality for the further exploitation of the natural resources on the adjacent territory.
