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.

Modernization of Chemical Workshop of the Pumping-Filter Station of Samara Using the Powdered Carbon Sorbent
Summary
Modernization of the chemical workshop carried out at one of unit of the pumping-filter station of Samara with 360 thousand m3/day output has made it possible to improve the reliability of water treatment. The flow chart includes the primary chlorination, dosing of powdery activated carbon into influent water, coagulant addition before the mixer, flocculant addition at the passage of water from the mixer, clarification in horizontal settling tanks, filtration in rapid filters, secondary chlorination. The use of powdered activated carbon in the water treatment scheme ensures the quality of potable water corresponding to specified requirements.
