DEVICE FOR DEFERRIZATION OF WATER WITH OZONE-AIR MIXTURE Russian patent published in 2021 - IPC C02F1/64 C02F1/78 

FIELD: water purification systems.

SUBSTANCE: invention relates to systems for the purification of natural waters of underground and surface sources, in particular to deferrization, demanganation, oxidation of organic substances by ozone. The device for deferrizing water with an ozone-air mixture contains an ultraviolet lamp 1 in a housing 2 equipped with a branch pipe 3 with a first valve 4 for air supply and a branch pipe for removing the ozone-air mixture 5 supplied to the passive cavity of the ejector 6. Water is supplied to the inlet 7 of the ejector under pressure, and the outlet of the ejector connected to a conical divider 9 located in the lower part of the mixing chamber 16, into the body of which the Pall ring nozzle 31 is filled. On the cover of the mixing chamber 16 there is an air valve 11 with a branch pipe 12, which drops to the water level in the mixing chamber, connected through a carbon cartridge 15 in the filter housing 14 with a drain. The upper part of the mixing chamber is connected by a tube 17 to the inlet of the filter 19 operating mode regulator located on the sand-gravel filter, the outlet of which is connected to consumers through the housing 27 of the second ultraviolet lamp 28 and the second valve 29. The mode regulator 19 has three branch pipes, one of which is lowered into the upper part of the filter above the sand and gravel backfill 22, the second is lowered into the lower part under the sand and gravel backfill 23, and the third branch pipe 24 connects the filter operating mode regulator 19 with drainage.

EFFECT: efficient water purification with ozone-air mixture with exclusion of residual ozone in treated water.
