PROBLEMS, PERSPECTIVES
Petrov B. G. DEVELOPMENT OF WATER MANAGEMENT IN THE REPUBLIC OF TATARSTAN The problems and perspectives of development of water management in the Republic of Tatarstan are covered, the priority directions for providing the republic's population with potable water of high quality are shown.	2
Zholdakova Z. I., Polyakova E. E., Artemova T. Z., Ivanova L. V., Myasnikov I. N., Potanina V. A. HYGIENIC ASSESSMENT OF THE METHODS OF WATER TREATMENT AND DISINFECTION WITH COAGULANTS AND AVAILABLE CHLORINE On the basis of the research results it was found that the use of polya-luminium chloride allowed to eliminate the primary chlorination or to reduce essentially the portion of available chlorine. The use of coagu-lants does not exclude and does not replace the chlorination at the final stage of water treatment as it's necessary for providing the bactericide effect in the distribution network.	9
Myasnikov I. N., Potanina V. A., Zholdakova Z. I., Artemova T. Z. THE STUDY OF COAGULATION AND DISINFECTION PROCESSES IN THE COURSE OF SURFACE SOURCE WATER TREATMENT The use of ÀÊÂÀ-ÀÓÐÀÒ"18 and ÀÊÂÀ-ÀÓÐÀÒ"10 aluminium polyoxychlorides as reagents for water treatment does not lead to crea-tion of chlororganic at the sedimentation and filtration stages. These reagents possess also high disinfection effect comparing with aluminium sulphate.	13
Getmantsev S. V., Ruchenin A. A., Snigirev S. V., Churikov F. I. ASSESSMENT OF EFFICIENCY OF THE USE OF DIFFERENT TYPES OF COAGULANTS FOR THE VOLGA'S WATER TREATMENT Efficiency of the use of different types of coagulants for the Volga's water treatment according to sanitary, hygienic and economic criteria has been estimated. It shows essential superiority of aluminium poly-oxychloride over aluminium sulphate.	17
Safin R. N., Bazin S. V., Getmantsev S. V., Churikov F. I. EVALUATION OF ECONOMIC EFFECT AS A RESULT OF THE COAGULANTS USE The principles of assessment of operating costs in the processes of natural and waste waters purification with coagulants are presented.	21
Getmantsev S. V., Sichev À. V., Churikov F. I., Snigirev S. V. PECULIARITIES OF COAGULATION MECHANISM AND ALUMINIUM POLYOXYCHLORIDE STRUCTURE The peculiarities of coagulation mechanism and ÀÊÂÀ-ÀÓÐÀÒ"30 polymeric, inorganic coagulant's structure have been analyzed; its efficiency has been compared with the effect of monomeric aluminium hydrooxychloride.	25
Konstantinov D. V., Pomosova N. B., Tatura A. E., Snigirev S. V. THE STUDY OF EFFICIENCY OF NEW DOMESTIC REAGENTS AT THE WATER STATION OF THE CITY OF SARAPUL The higher efficiency of the use of new domestic reagents - ÀÊÂÀ-ÀÓÐÀÒ"30 aluminium polyoxychloride and alumoferric coagulant - for water treatment comparing with aluminium sulphate is shown.	29
Bazin S. V., Getmantsev S. V., Nasiybullin G. R., Nurullina I. I., Yusu-pov Sh. K., Sklyarova T. T. THE USE OF ALUMINIUM POLYOXYCHLORIDE FOR TREATMENT OF THE KAMA'S WATER Replacing aluminium sulphate with ÀÊÂÀ-ÀÓÐÀÒ"30 aluminium polyoxychloride for the Kama's water treatment will allow to reduce expenditures for reagents and receive potable water conforming to the specifications now in force.	33
Churikov F. I., Snigirev S. V., Ruchenin A. A., Getmantsev S. V. REDUCTION OF WASTE WATER DISCHARGE AT THE WATER TREATMENT FACILITIES OF KAZANORGSINTEZ PUBLIC COMPANY The technology of the reuse of wash water, dewatering and utilization of sludges with AKBA-AÓÐÀÒ"30 coagulant in the presence of «Ïðàåñòîë» flocculant is described.	36
