Energy conservation and alternative power sources at the wastewater treatment facilities
Summary
Methods of improving power efficiency of the municipal wastewater treatment facilities and heat and electrical power generation with the use of renewable power resource of wastewater. The analysis of power conservation and generation in water supply and wastewater management shows that depending on the technical solutions applied the total balance of power consumption at the water and wastewater facilities can vary from the net electrical energy consumption of 4 MW per 100 000 m3 of wastewater/day to positive balance of 7,5–8 MW (owing to 16 MW power generated including 1 MW of electrical energy). The power consumption of two independent municipal wastewater treatment plants can differ more than 6 times.

Experience of Introduction of Ecopolymer Equipment in Countries of the Eastern-Asian Region
Summary
The experience of introduction of the Ecopolymer Group’s equipment in the countries of the Eastern Asian Region on the example of China and South Korea is described. In China aerators are used for treatment of municipal (communal) and industrial-municipal discharges (in industrial parks) and for treatment of industrial enterprises wastewater as well. The equipment introduction is made mainly at large treatment facilities of over 150 thousand m³/day capacity. In South Korea the Ecopolymer aerators are used at treatment facilities of concentrated flows with high concentration of activated sludge from unloading plants, pig farms, poultry factories, in systems with membrane technologies of wastewater treatment.

Improvement of Operational Reliability of Wastewater Disposal System of Moscow
Summary
The reliable and efficient operation of the wastewater disposal system of Moscow is one of the most important components of sanitary and ecological well-being of the city. Under the conditions of water saving and an annual reduction in volumes of water consumption and wastewater disposal the priority directions of development of the wastewater disposal system are improvement of water treatment quality and reliability of networks and facilities operation. With that end in view the Moscow State Unitary Enterprise Mosvodokanal (MSUE) introduces new methods of renovation of sewerage networks using widely up-to-date computer technologies and geoinformation systems, carries out the reconstruction of water treatment facilities. This complex of measures makes it possible to reduce considerably the risk of emergency situations.

Storm Sewer Development in Baku
Summary
Basing on the results of theoretical and experimental investigations a process scheme providing for chemical free treatment of polluted storm water in a compact float-filter placed in a circular settler is proposed. As may be required tertiary treatment by filtration through inert media is applied. The recommended technology can be applied in developing the Master Plan of surface runoff removal and treatment in the city of Baku. The technology provides for integrated treatment of storm water with pollution concentration reduction to the set limits. The effluent can be reused as process water for industrial enterprises, auto washing, street washing and irrigation of planted land.

Ecological Rehabilitation of the Moscow Municipal Wastewater Disposal System
Summary
The suggestions about modernization of the disposal and treatment system of surface runoff from the territory of Moscow with due regard for environmental requirements set for water objects-water receivers have been developed by specialists of MosvodokanalNIIproekt on the basis of investigations of many years. The prognosis of possible reduction in pollution level of the city’s water objects as a result of execution of complex of measures aimed at the reconstruction of the wastewater disposal system and enhancement of the level of improvement of the city’s territories has been made on the basis of the analysis of change of pollutants concentration in the surface runoff in the course of its movement along the different parts of the wastewater disposal system. The suggestions take into account interconnection and interaction of all city’s water-management systems and can be used for search of optimal solutions concerning organization of surface runoff disposal and treatment for certain water collecting basins as well as in the course of actualization of the General scheme of disposal and treatment of surface runoff from the territory of Moscow together with the Program of rehabilitation of the city’s water objects.
