There is provided an inline saturator system and method for gas exchange with an aqueous-phase liquid. The system includes a pressure vessel, configured to receive a first liquid and a first gas from external sources and to discharge a second liquid and a second gas from the pressure vessel, and a gas infusion device situated within the pressure vessel. The gas infusion device is configured to receive the first liquid and first gas, to facilitate gas exchange therebetween, producing the second liquid and the second gas, and to discharge the second liquid and second gas into the pressure vessel. The system further includes a recirculation system configured to direct a portion of liquid within the pressure vessel back into the saturator device, where injection of the redirected liquid into the gas infusion device forces the first liquid into the gas infusion device for the gas exchange.

The description relates to methods and apparatus that enable the efficient introduction of gases like air, oxygen and ozone into aqueous liquids. Gases are introduced into liquids for making that gas chemically or biologically available at a minimum energy expenditure. Impinging jets of liquid are directed into a pressurized saturation vessel having a gas-filled headspace and a saturation zone below the surface of the liquid at a velocity sufficient to create a turbulent impact and plunge zone. The resulting turbulence and mixing of gas and liquid in that zone under pressure, causes the gas to be driven into the liquid in the vessel and breaks up the gas and the liquid into a churning flow and creates a large number of bubbles. The resulting gas-enriched liquid is discharged from the vessel at an outlet to ensure a minimum of bubbles in the gas-enriched liquid.
