FLOATING CLARIFYING WATER INTAKE STRUCTURE Russian patent published in 2007 - IPC E03B3/04 E03B3/32 

FIELD: hydraulic and water supply engineering, particularly water intake structures to take and clarify water to be produced from water sources characterized by large water level fluctuation and suspension particle content.

SUBSTANCE: water intake structure comprises body with thin-layered module installed therein, accumulation vessel connected with thin-layered module. The thin-layered module comprises opened bottom part. Water is sucked from accumulation vessel through sucking pipeline with the use of pump and is supplied via pressure pipeline. Horizontal pipes are installed in clarifying module in staggered order. The horizontal pipes are provided with slot-like perforation orifices arranged in upper and lower parts thereof and extending along horizontal pipe lengths. Zigzag split directly communicating pipes with river is formed in outer pipe surfaces. The zigzag split provides precipitated suspension particle discharge in river. Water intake structure has water-receiving chamber filled with ball members and is provided with horizontal grid located in lower part thereof. Water taken from water source and incoming reagents move via said horizontal grid.

EFFECT: increased efficiency of water clearance of suspension particles due to particle precipitation in reagent presence, decreased thin-layered module size, which provides structure usage in shallow water bodies.
