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

FIELD: water treatment.

SUBSTANCE: invention relates to systems for purifying natural waters of underground and surface sources, in particular to deferrization, demanganization, oxidation of organic substances by ozone. Device for deferrization of water with ozone contains a ultraviolet lamp in a housing equipped with nipples for supplying air and discharging an ozone-air mixture supplied into the passive cavity of the ejector, to the input of which water is supplied under pressure, and a sand-gravel filter. On the air supply branch pipe into the ultraviolet lamp housing the first valve is installed, and the ejector output is connected to the divider located in the upper part of the mixing chamber, on the cover of which there is an air valve with a pipe lowering to the level of water in the mixing chamber, connected through the housing of the second ultraviolet lamp with a drain. Lower part of the mixing chamber is connected to the inlet of the filter operating mode regulator located on the sand-gravel filter, the outlet of which is connected to the consumers through the third ultraviolet lamp housing and the second valve. Mode regulator has three branch pipes, one of which is lowered into the upper part of the filter above the sand-gravel charge, the second one is lowered into the lower part under the sand-gravel charge, and the third branch pipe connects the regulator of the filter operation mode with the drainage.

EFFECT: providing purification of water with elimination of residual ozone in treated water.
