ARTESIAN WATER PURIFICATION METHOD Russian patent published in 2023 - IPC C02F9/00 B01D61/14 

FIELD: ecological protection of the environment.

SUBSTANCE: water supply for settlements and ecological protection of the environment. Invention can be used for purification of artesian waters and obtaining drinking water. The purification method includes aeration of water with atmospheric air during treatment in a tangential axis liquid and air aerator, acceleration of the processes of oxidation of the dissolved metal compounds contained in it and their conversion into an insoluble form in the process activation unit, and separation of insoluble metal compounds from the treated water. The separation of insoluble metal compounds from treated water is carried out by means of a microfiltration filter. Water is supplied to the tangential axis liquid and air aerator by a pump installed on the artesian water pipeline. After treatment in the process activation unit, the water is passed through a microfiltration filter. Periodically, the microfiltration filter is washed with a reverse flow of purified water, removing the formed precipitation from iron oxides from the treated water, and the insoluble compounds washed off with reverse water are removed.

EFFECT: increasing the degree of artesian water purification, reducing the content of iron compounds in artesian water, reducing the alkalinity and hardness of water, reducing the concentration of organic inclusions, as well as the possibility of obtaining drinking water in small settlements without the use of expensive chemicals.
