Abstract

During the process of cleaning natural waters, a large amount of highly waterlogged sediment is formed, which is a potential source of environmental pollution. The development of water supply station capacities, increasing requirements for the creation of energy-saving technologies and environmental protection necessitate the treatment of water supply station sludge. In practice, the following main directions of processing water sludge are used: discharge of sludge into surface watercourses and reservoirs, burial in the open sea, dewatering of sludge in natural conditions, drying of sludge on sludge beds in evaporation or freeze-thaw mode, mechanical dewatering of compacted sludge in chamber or belt filter presses or in centrifuges with preliminary conditioning using reagents, removal with sludge from sewage facilities by discharging water sludge and wash water to sewage treatment facilities. This article is devoted to the issue of treating sludge from drinking water treatment plants in the city of Almaty. The results of laboratory studies on the selection of an effective flocculant for dewatering sludge from wastewater treatment plants are presented. It was determined through laboratory and experimental methods that high-molecular flocculants of the Praestol 650 TR and Flopam AN 913 SH brands are most effective when dewatering water supply sludge from treatment plants in the city of Almaty. These flocculants showed good results in two out of three indicators. The best result in terms of water yield and purity of liquid separated during precipitation.

Natural water, water treatment, sump, plumbing sludge, flocculant, sludge treatment, flocculant dosage.
