Vasiljuk A. Substantiation of water treatment technologies in decentralized systems of drinking-water supply

Object - preparation of water in the drinking-water supply; the purpose - creation of scientific basis of preparation of water in decentralized systems of domestic and drinking water supply for the reliable provision of the population with quality drinking water while reducing capital and operating costs; methods - of modeling of processes of treatment of natural water at the stations with bio-reactors and contact-clearing filters; results - theoretically expediency of decentralized systems of economic and drinking water supply and the technological scheme of structures in the head water supply, which includes waterworks-treatment facilities, bioreactor, contact-clearing filter and water decontamination system technical sodium hypochlorite; the novelty is developed approximate mathematical model of the processes of water purification on the installation and set the main factors affecting the work of the contact-clarifying solutions of the filter, on the basis of theoretical and experimental data the methods of determining their optimal design and technological parameters; the introduction of the reduced cost of water treatment facilities, increased reliability water supply and security in the preparation of technical water; use - developed technologies were introduced at a wastewater treatment plant Kiliya group water pipeline Odessa region, and formed the basis for the development of Indication to the VBN V. 46/33-2.5-5-96"Agricultural water supply. External networks and structures. Design norms".
