GROUNDWATER PURIFICATION METHOD DURING WATER TREATMENT AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2023 - IPC C02F1/72 B01F25/30 

FIELD: groundwater purification.

SUBSTANCE: purification of groundwater from iron, manganese, with the simultaneous removal of hydrogen sulfide and other harmful gases using jet pumps designed to mix liquid and gas, used in water treatment systems for water supply of settlements, individual objects and agricultural complexes. The device contains a fast pressure filter and an ejector for saturating the raw water flow with gas. In the body of the ejector 5 there is a raw water supply nozzle 1 mated with the mixing chamber 6, a diffuser 7 and an air chamber 2 with an opening for gas supply 3. Air or an ozone-air mixture is used as the gas. The electric motor of the borehole pump and the unit for producing the ozone-air mixture are switched on and off due to the ejector located in the housing in the hole for supplying gas to the float rod 4 with a magnet fixed at its end.

EFFECT: implementation of aeration of groundwater supplied from the well to fast pressure filters, when the flow rate of the treated water changes from zero to the maximum calculated value; automation of the supply of ozone-air mixture to the ejector.
