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.
