WATER INTAKE FILTERING STRUCTURE WITH BIOPLATEAU STREAM FOR WATER TREATMENT Russian patent published in 2025 - IPC E02B9/04 E03B3/36 

FIELD: hydraulic engineering.

SUBSTANCE: invention relates to hydraulic engineering, namely to water intake facilities used for water intake on sections of rivers with complex hydrological conditions and contaminated flows. Water intake filtering structure with a stream of bioplateau for water purification comprises a water intake gallery with a filtering water intake consisting of a metal grid and filtering flexible mattresses laid on top of it, made of light fascines wrapped in a geonet, on top of which geotextiles are stretched. Water intake gallery is arranged nearby and along the river, from which a supply channel is erected to the beginning of the gallery in the form of a bioplateau stream filled with a mixture of gravel and crushed stone and planted with club-rush, reedmace, iris and other higher aquatic plants, which provide purification of river water supplied to the water intake gallery. Mark of the bottom of the end part of the supply channel, which is interfaced with the water intake gallery, is made above the mark of the surface of the filtering water intake. At the end of the water intake gallery, a water-collecting well is arranged, equipped with a water intake pipeline, which provides the supply of treated and filtered water to the water consumer, and on the top of the well on the side in the wall above the surface of the water intake from flexible mattresses and geotextile there is a spillway for discharge of excess water into the discharge channel.

EFFECT: water intake filtering structure with a stream of bioplateau for water purification can be effectively used on foothill and on flat sections of small rivers with complicated hydrological conditions and contaminated flows.
