Abstract
Abstract For efficiently dissolving a gas in liquid and introducing the solution of gas and liquid in a body of liquid, the gas initially is mixed with liquid. The mixture of gas and liquid is then subjected for an adequate length of time to a pressure sufficiently greater than that prevailing at the liquid surface of the liquid body for the gas to dissolve in the liquid to form a solution of the gas and liquid. Without any significant change in pressure, the solution of gas and liquid is then introduced free of turbulence into the body of liquid below the liquid surface level thereof.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
192 words
The method of forming a solution of gas and liquid and introducing such solution into a body of liquid which comprises the steps of a. mixing the gas with liquid, b. flowing the mixture of gas and liquid upwardly in a place out of physical contact with the body of liquid, c. subjecting the mixture of gas and liquid for at least 3 minutes, during upward flow thereof in such place, to a pressure sufficiently greater than that prevailing at the liquid surface of the liquid body for the gas to dissolve in the liquid and form a solution of the gas and liquid, d. continuously collecting and removing undissolved gas from the upper part of said place, e. flowing only the solution of gas and liquid free of turbulence from the upper part of said place to a region of the body of liquid below the surface level thereof without any significant change in pressure, and f. inducing flow of the solution of gas and liquid free of turbulence from the upper part of said place solely by displacement of such solution by the gas and liquid introduced into said place.
