Abstract

An apparatus for dissolving gas into water from a lake, pond or the like, including a housing having a surface defining an enclosed volume, a water intake conduit having an external inlet end and an outlet end inside the housing between which water flows through the housing, a reservoir within the housing having first and second apertures, the first aperture positioned to receive liquid discharged from the outlet end of the liquid intake conduit, a liquid evacuating conduit having an inlet internal to the housing and an outlet external to the housing for conducting water through the housing, the inlet end of the liquid evacuating conduit being sealed about the second reservoir aperture to evacuate the water, a water atomizer within the housing and positioned between the liquid intake conduit outlet and the first reservoir aperture to atomize the water before the water enters the reservoir, and a gas intake conduit with an inlet end connected to the housing exterior and an outlet end inside the housing to conduct gas into the housing, the conduit outlet end being in flow communication with the atomizer to create a gas barrier through which the liquid subparts must pass before entering the reservoir.

Dependent claims

An apparatus for aerating water in a lake or pond comprising:

a housing having a wall defining an enclosed volume,
means for intaking water comprising first means for confining water flow extending through the housing wall, the first water confining means having an inlet for receiving water from outside the housing and an outlet for discharging water into the enclosed volume,
a reservoir formed within the enclosed volume of the housing, the reservoir having an aperture positioned relative to the outlet of the first confining means no receive water discharged therefrom,
means for evacuating water from the reservoir to outside the housing comprising second means for confining water flow extending through the housing wall, the second water confining means having an inlet for receiving water from within the housing and an outlet for discharging water externally of the housing, the inlet of the second water confining means being in flow communication with the reservoir to permit evacuation of water therefrom,
means for atomizing water located within the housing and positioned between the outlet of the first water confining means and the reservoir aperture to atomize the water before the water enters the reservoir, and
means for intaking gas comprising means for confining gas flow extending through the housing wall, the gas confining means having an inlet for receiving gas from outside the housing and an outlet for discharging gas to the enclosed volume of the housing, the outlet of the gas confining means being in flow communication with the water atomizing means to allow gas flowing from the outlet of the gas confining means to mix with the atomized water from the water atomizing means.
