WATER TREATMENT HYDROAUTOMATIC STATION BASED ON DELTA-FILTRATION TECHNOLOGY Russian patent published in 2023 - IPC C02F1/00 B01D24/48 

FIELD: water supply and sanitation.

SUBSTANCE: station includes a pressure filter with a granular filling, an air tube with a vent and a normally closed check valve, a reaction chamber, a central pipe with a funnel and an automatic unequal-arm shut-off valve with a seal and a latch, a source water pipe with a chemical input unit and a nozzle coaxial with the central pipe and buried in it, drainage with a normally closed non-return valve and a device for disinfecting the filtrate, a filtrate tank with a water exchange hole, an air exchange tube with a plunger and a valve. A return filter and a water distribution system are located under the filling. The drainage system is connected to the water distribution system. The elements of automating the loading structuring process are interconnected mechanically. The valve is attached to a vertical rod, which is passed down through a timer with a time setting movable washer on the rod, a retainer and a spring. The rod is passed through the passage hole into the tank as a mechanical signal line with a sensor for the perception of the variable buoyancy force of Archimedes from the drive at the lower end of the rod. The valve comprises a full opening stop. The drive includes a pressure filter with a granular filling, an air tube with a vent and a normally closed check valve, a reaction chamber, a central pipe with a funnel and an automatic unequal-arm shut-off valve with a seal and a latch, a source water pipe with a nozzle coaxial with the central pipe and buried in it, a filtrate tank with a water exchange hole, an air exchange tube with a plunger and a valve.

EFFECT: elimination of delay in water supply to the water supply system, reduction in energy costs, increase in the filtration period, increase in the reliability of the station.
