Architectural view – continued


The architecture department of the «MosvodokanalNIIproject» JSC, in addition to designing harmonious appearance and interiors of the facilities always solves the problem of providing for logical and clear space-planning structural arrangement of buildings, ensuring the optimal functioning of technological processes and engineering systems, comfortable working conditions for the staff. Based on this approach, for the last 5 years numerous projects have been developed and implemented that are considered in terms of specific
features and requirements of architecture design. The most significant water and wastewater treatment projects are presented. Of these there is reconstruction of the Kuryanovo and South-Butovo wastewater treatment facilities in Moscow, construction of water treatment facilities at the Western water treatment plant. The issue of designing wastewater treatment facilities in the territory of New Moscow, in particular, in the village of Rogovo, is touched upon. The expanding segment of designing urban sanitation facilities is considered in detail. Of these are «EcoTechnoPark «Kaluga». Successful case studies of cooperating with third-party contractors, in particular, on the Moscow oil refinery, and the Khovrinskaia pumping station are presented.

Hygienic regulation of drinking water quality as a mainspring of the water treatment technology upgrade


The aspects of developing the domestic regulatory environment on drinking water quality are considered together with the effect of the tendency of introducing additional requirements on the water treatment technology by the example of the Moscow public water supply. The drinking water quality requirements both in our country and abroad are based on the criteria established by the World Health Organization in the middle of the last century. In different countries the requirements may differ depending on the national drinking water policy represented by the legislation, standards and other statutory regulations. In the Russian Federation the drinking water quality standards are determined by the sanitary-epidemiologic legislation that specifies the maximum permissible concentrations of all the regulated pollutants. The current requirements to the drinking water quality determine the process solutions implemented at the water treatment plants. Introduction of the new regulatory requirements has become a powerful impulse to upgrading the existing facilities and retrofitting new advanced methods into the treatment technology. Thus, tightening the regulations on the concentration of chlorination byproducts and the requirements to the epidemic safety (regulating viral and parasitary contamination) resulted in the methodical work on upgrading the Moscow water treatment plants with the introduction of ozonation and activated carbon filtration and membrane filtration. Even today the water treatment plants with advanced treatment facilities that guarantee water purification to the regulatory requirements supply more than 40% of the Moscow drinking water. At the same time the current regulatory documents contain inconsistencies that necessitate taking expensive measures to improve the drinking water quality. Considering the activities on revising the current requirements it is necessary to pay special attention to the harmonization of separate statutory regulations.

Improving barrier functions of the Metelevskii water treatment facilities of Tumen city


The results of the preliminary tests showed that during the periods of elevated pollution of the water source (the Tura River) with different toxicants, natural and anthropogenic odorants the process flow scheme with the use of specially prepared powdered activated carbon for the conditions of the Metelevskii water intake would be worth considering. The process flow diagram of the pilot test facility was designed that provided for modeling the existing water treatment technology at the Metelevskii water treatment plant. The pilot facilities included chemical treatment units, clarification units, filtration and disinfection units. During water treatment process modeling the chemical dosages used (ammonium sulfate, chlorine, aluminium oxychloride and polyacrylamide) were similar to those at the Metelevskii water treatment plant for the moment the tests were carried out. According to the results of the tests the trademarks of powdered activated carbon used were defined as most efficient for odor and toxicant removal (by example of phenol). Before dosing into the water the sorbents were specially prepared (following the technique of NII VODGEO) to provide for maximum exhibiting sorption properties in relation to the mentioned target components. Special pilot equipment designed at NII VODGEO allowed reproducing all the water treatment modes applied at certain facilities. This modeling provides for adjusting water treatment technology, developing new process solutions, selecting new chemicals and dosages without interrupting the operation of the basic facilities. The results of the tests and pilot investigations with the use of powdered activated carbon at the Metelevskii water treatment facilities to remove anthropogenic toxicants and odors are presented. Powdered carbon trademarks were selected; recommendations for designing powdered activated carbon unit were given.
