Introduction of Up-to-Date Technologies of Potable Water Treatment

Summary

The modern conception of water treatment has been realized at the pumping-filtration station of 250 ths m³/day output supplying potable water to the left-bank part of the city of Novosibirsk. The scheme of water treatment includes preliminary water ammonization, the supply of coagulant (aluminum oxychloride) and flocculant, preliminary chlorination, mixing in a mixer of instantaneous action, preliminary flocculation, clarification in horizontal settling tanks, filtration at high-rate filters, secondary chlorination, UV-disinfection. The use of several technologies and technical decisions in the scheme of water treatment aimed at the ensuring of epidemiological safety and high quality of water makes this scheme exclusively reliable and universal.
