Abstract:
A method for mixing a liquid solution including dissolved gas into a liquid comprising:providing a first liquid and a gas and dissolving said gas in said first liquid under pressure to form a liquid solution including said dissolved gas; providing an elongated body with a hollow formed therein and having a liquid solution inlet coupled to said elongated body, said elongated body defining an interior path from said liquid solution inlet through said hollow; providing at least one outlet hole in said elongated body for flow of said liquid solution from said hollow to the exterior of said elongated body wherein the outlet hole is sized to maintain system back pressure on said liquid solution to maintain the dissolved gas in said liquid solution within said elongated body wherein the pressure drop across said back pressure is about 45 to about 55 psi; orienting said elongated body in the bottom of a mixing chamber containing a second liquid to permit the flow of said liquid solution upward within said mixing chamber; and passing said liquid solution through said interior path of said elongated body and through said outlet hole into said second liquid to mix said liquid solution into said second liquid.
