Common problems at water treatment facilities and ways to address them

Summary

Due to the anthropogenic factors, the quality of surface water is subject to rapid, mainly negative, changes; therefore, water treatment plants not always can meet the standards of the drinking water quality. Currently, many water treatment facilities are in need of upgrade, re-technologization and even reconstruction. In addition, significant changes in the actual water supply by the water facilities (decreasing, as a rule) do not always produce a positive effect on the technical and economic indicators of the water treatment facilities. Problems arising during the operation of the water treatment facilities at all stages of surface water purification – microfiltration, chemical treatment, mixing with chemicals and flocculation, sedimentation, filtration and wash water treatment are summarized. The methods used by MY PROJECT JSC in its projects to address such problems as the lack of the treatment efficacy, overspending of chemicals, short filter cycle, large water losses for process needs, discharge of untreated wash water, high purification cost are considered.

Improving the water treatment technology at the West water treatment plant

Summary

In January 2011 newly built ozonation and activated carbon filtration facilities with a capacity of 250,000 m3/day were put into operation at the West water treatment plant in Moscow. The facilities are fully automatic. Monitoring and control of the treatment process is carried out from the central control room. The technology of ozonation in combination with activated carbon filtration ensures high efficiency of organics removal (color, permanganate oxidability, total organic carbon), deodorization, and improvement of the drinking water taste, allows minimizing the formation of chlororganics (chloroform). The amount of water treated with new technology was 490,000 m3/day or 43% of the total supply to the city.
