<p>A device for infusion of gas into fluid, off gassing said fluid and returning said off gassed fluid to a body of fluid, comprises an intake tube having a bottom opening submergable below a body of fluid, gas diffusion means positioned within a bottom portion of said intake tube for infusing gas into fluid within said intake tube, whereby the rising bubbles of infused gas drives the liquid in the intake tube upwardly to a top portion of the intake tube and through a cross tube section in communication with said intake tube portion, said cross tube section extending substantially perpendicularly to said intake tube and above said body of fluid to an off gassing section, said off gassing section extending above the cross tube section and allowing said liquid to have surface exchange with the air and thus removal of gasses from the liquid and being positioned above the body of water, thereby creating a head differential. A discharge tube portion communicates with the cross tube, being positioned below said off gas section and extends downwardly therefrom into the body of fluid, whereby the fluid entering the discharge tube has imparted a downward velocity due to the head differential between the liquid at the top of the off gassing section.</p> |
