METHOD OF WATER AERATION AND DEVICE FOR ITS REALISATION Russian patent published in 2014 - IPC C02F7/00 

FIELD: chemistry.

SUBSTANCE: invention can be used in enrichment with air oxygen of natural and artificial water bodies, in particular stagnant zones in the process of purification of household and industrial sewage waters in biological ponds, as well as in premises on treatment plants of water supply. Aeration method includes intake of limited portion of water from water body, its isolation from water body, creation of excessive pressure on said portion surface by physical body weight, formation of flowing of speed water jet into mixing chamber, ejection of air from atmosphere by said jet, mixing water and air, discharge of water-air mixture into water body, returning physical body-displacer into initial position. Device contains water-receiving pipe with suction valve, placed on pontoon, physical body-displacer with water-lifting pipe, located inside water-receiving pipe with possibility of reciprocating movement, hung on short arm of equal-arm rocker, which has intermediate water-collecting reservoirs, equipped with siphon drainpipes, on each arm.

EFFECT: invention makes it possible to carry out water aeration due to energy of Earth gravitation field both in open water bodies and in premises.
