Introducing innovative materials and technologies in the water distribution network

Summary

A review of the advanced innovative materials and technologies used in reconstruction and operation of the water distribution network is presented. The basic causes of pipeline failure are considered, the advanced technologies and equipment that contribute to extending the pipeline operational life are described. A comprehensive analysis of the newly developed corrosion-resistive coatings, socket joints is given alongside with the results of retrofitting energy-independent systems of monitoring water distribution network parameters based on multiparameter sensors and remote control of the shutoff and control valves. The experience of MPUE Mosvodokanal in using innovative trenchless technologies of pipeline repair and rehabilitation is systemized.

Experience in Operation and Enhancement of Water Disinfection System with the Use of Sodium Hypochlorite

Summary

Over ten years ago at the water treatment facilities of the city of Seversk the operation of the disinfection system with the use of liquid chlorine was converted to the use of sodium hypochlorite. At present the modernization of equipment due to the application of aerohydrodynamic mixers was made, the processes of mixing the reagent with water being treated were intensified, the operation of reagent facilities was completely automated including the dosing of sodium hypochlorite proportional to water flowrate.

The use of advanced technologies at the Head water treatment facilities of the Khabarovsk water supply system

Summary

A project of constructing the second stage of the Head water treatment facilities of the Khabarovsk water supply system was developed. The project was designed with an account of the specific composition of the water source pollution and with the use of advanced water treatment technologies. The water treatment complex will include the following facilities: settlers and filters, powdered activated carbon addition and ammoniation stages, an upgraded pumping station at the outlet of the treatment facilities with UV-disinfection stage, an advanced bacteriological laboratory.

Efficient control of water supply and distribution system of the Moscow megalopolis

Summary

The existing system of Moscow water supply is a comprehensive complex of engineering facilities that provide for uninterrupted supply of potable water to the city inhabitants. The main task of the system control is to assure delivering the required amount of high quality potable water alongside with maintaining optimal operation mode of all the water facilities. The main aspects of the efficient water supply control are as follows: predicting daily and hourly water consumption in the city; planning amount of delivery by the water treatment facilities; assuring operational control (of pressure, quality); computerizing control processes. Improving the efficiency of such a large-scale system may be possible only by investigating and introducing innovative solutions, integrated use of information technologies including GIS, modeling flow distribution in the water distribution network, and computerizing water delivery and distribution modes.

Efficiency of Natural Water Disinfection in the Course of Coagulation Treatment

Summary

Results of experimental and theoretical studies of the coagulation treatment of the Don water and monitoring of the concomitant process of its disinfection are presented. The mechanism of separation of algae, bacteria and viruses from water due to their sorption on aluminium hydroxide generated in the course of coagulation is described. The best effect of water disinfection observed during electrocoagulation is 93,8%. The use of this method makes it possible to abandon the primary water disinfection with chlorine, exclude a large-size reagent services and improve the ecological situation in connection with reduction of the volume of the generated sludge (waste of coagulation process).
