WATER SUPPLY AND DRAINAGE SYSTEM IN WEAVING PRODUCTION Russian patent published in 2024 - IPC C02F9/00 

FIELD: technology of water and air purification.

SUBSTANCE: invention relates to buildings and structures intended for continuous treatment of waste water in weaving industry. System includes a well water treatment system and a system of treatment facilities for continuous treatment of waste water and flushing water. Water treatment system comprises an underground tank of treatment facilities, mixers with a coagulant and a flocculant, solution-consumable tanks of coagulant and flocculant with feed pumps, a settling tank, a tank for collecting clarified water with feed pumps, a tank for collecting additional purified waste water, sludge collectors, pumps for supplying sludge to a filter press, a filter press. Treatment plant system includes a mixer of industrial waste water, a drum brush grid, a balancing device, pumps for supplying process water to the balancing device, an intermediate tank of conditionally clean storm waste water, storm waste water supply pumps for filtration, storm waste water mechanical clarification filter, water supply pumps from balancing device, two-section flow reactor with mixers, waste water mixer with coagulant, pH correction tank with a mixer, water supply pumps for post-treatment, a flotation unit, a post-treated waste water collection tank connected to the waste water supply pumps for filtration, mechanical clarifying filters, oxidizer reactor, an ozonization station, including an ozone generator, an oxygen station and a residual ozone decomposer, bleached water supply pumps, decolored water collection tank, discolored waste water supply pumps for filtration, purified waste water supply pumps for filter washing, sorption carbon filters, an underground reservoir of pure water, filtered water supply pumps to a reverse osmosis plant, a desalination plant, a reverse osmosis concentrate collection tank, a clean water collection tank, pure water supply pumps, a sludge treatment unit, unit for preparation and supply of reagents—lime milk, antifoaming agent, coagulant and flocculant.

EFFECT: possibility of reuse of treated water in production with replenishment of service water from wells or conditionally pure rain water from roofs of a building.
