Complex Assessment of Processes of Wash Water Treatment at Water Supply Stations of the Western Siberia

Summary

Methods of treatment of wash water of water supply stations located at surface water sources of the Western Siberia are considered. The technology of the multiple use of wash water in the technological process at main facilities of pumping-filtration stations is offered. The basic properties of natural and wash waters are defined, sizes of the facilities required for qualitative treatment of wash water are calculated. Results of the experimental study and calculations made prove the possibility of application of the main technological scheme of natural water treatment (horizontal settling tanks and rapid filters) at operating treatment facilities for wash water treatment.

Summary

Results of the study of processes of water treatment for suspended substances are presented. In the course of calculation of facilities and apparatuses used for extraction of the suspended phase of contamination, it’s necessary to take into account its disperse composition, density, concentration, surface properties of the liquid phase and the indicator of flows dynamics.
