Abstract: A system and method of controlling a concentration of one or more gases dissolved in a beverage is shown. The system includes a saturation tank having a gas head space, a brite tank, and a beverage supply system to pass the beverage between the saturation tank and the brite tank. A beverage supersaturated with the gas from the head space is formed in the saturation tank. The supersaturated beverage is passed from the saturation tank to the brite tank. Once the amount of gas added to the beverage exceeds saturation, some of the gas escapes from solution from the beverage and the pressure in the brite tank increases. Once the pressure within the brite tank reaches a pre-defined pressure, a pump supplying the beverage to the saturation tank is shut-off and the inlet and outlet valves of the brite tank are closed.

Abstract: A system and method for carbonating a beverage is shown. The system includes a saturation tank having a gas head space of CO2, a carbonation tank, and a beverage supply system to pass the beverage between the saturation tank and the carbonation tank. A beverage supersaturated with CO2 from the head space is formed in the saturation tank. The supersaturated beverage is passed from the saturation tank to the carbonation tank. Once the amount of CO2 added to the beverage exceeds saturation, some of the CO2 escapes from solution from the beverage and the pressure in the carbonation tank increases. Once the pressure within the carbonation tank reaches a pre-defined pressure for the desired volume CO2/volume beverage, a pump supplying the beverage to the saturation tank is shut-off and the inlet and outlet valves of the carbonation tank are closed.

Abstract: Apparatus and methods for dissolving a gas into a liquid comprises a saturation tank, a high pressure liquid pump in fluid communication with the tank, and a pressurized gas source in communication with a regulated gas head space of the saturation tank. The saturation tank comprises a pressure vessel for containing the liquid and has a regulated gas head space above the liquid, contains at least one liquid spray nozzle that permits passage of liquid into the pressure vessel, and an outlet for the liquid containing dissolved gas. Upon passing the gas-containing liquid into a second fluid, the gas is released in the form of microbubbles. The microbubbles aid in flocculation of suspended particles and promote dissolution of the gas in the second fluid. Preferred gases for use with the apparatus are oxygen, air, and ozone. Anticipated uses include treatment of rivers, streams, and ponds in natural or industrial settings, as well as smaller scale applications.
