APPARATUS FOR CONTACT WATER CLARIFICATION Russian patent published in 2025 - IPC B01D21/08 

FIELD: performing operations.

SUBSTANCE: invention can be used in mining industry, food industry, municipal services, metallurgy, mechanical engineering and other industries. Housing (1) of the apparatus for contact clarification of water contains elements that ensure the flocculation process, the thin-layer settling process and contact filtration. Apparatus comprises housing with flocculation chamber (2) equipped with mechanical alternating device (17) made in form of vertical blades, and also comprises separate sectors of chambers for contact water filtration on filter bed and inclined thin-layer elements (9). Sectors of contact filtration chambers (22) are isolated from each other by blind partition walls (21). Apparatus also comprises purified water discharge pipeline (13), flushing water discharge pipeline (14.1), flushing water discharge pipeline from contact zone (14.2), made from each sector of contact filtration chambers (22) and combined with each other via shutoff valves.

EFFECT: invention provides improved flocculation due to the use of mechanical mixing with adjustable blade rotation speed and the use of blades of different cross-sections; high quality of purification in contact clarification (filtration) of water after clarification on thin-layer elements; reduced cost of water purification; reduction of capital costs for construction of facilities due to integration of treatment stages – thin-layer clarification and contact clarification (filtration) into one unit.
