Abstract: Method and apparatus for producing an oxygenated fluid. In accordance with various embodiments, a vessel of water is provided for housing a population of fish. A stream of oxygenated water is generated to have a dissolved oxygen content of at least about 70 milligrams/liter (mg/l). The stream of oxygenated water is diluted with a second stream of water to provide an output stream with a dissolved oxygen content of from about 5 mg/l to about 14 mg/l. The output stream is injected into the vessel to maintain the population of fish.

Abstract: Method and apparatus for producing an oxygenated fluid. In accordance with various embodiments, a flow of pressurized fluid is established. A flow of oxygen is injected into the flow of pressurized fluid to provide a fluid/oxygen mixture. The mixture is passed through a venturi assembly in the presence of a magnetic field established by an adjacent magnetic assembly. The mixture is next flowed from the venturi assembly to a gas/liquid separation tank, where a liquid component of the mixture is passed downstream with a selected dissolved oxygen content and a gas component is directed back for injection into the pressurized fluid flow.

Abstract: Apparatus and method for increasing dissolved oxygen levels in a liquid. An oxygenation system (100) includes a liquid source (102) from which liquid is introduced into a piping network (106) by a pump (104). Colloidal minerals are injected into the liquid in a dwell chamber (110). The mixture of liquid and minerals flows into an oxygenator (118) where gaseous oxygen is injected into the liquid. The resulting two-phase flow stream is accelerated to supersonic speeds through a linear flow accelerator (126) comprising a flat Venturi (130) and electromagnets (128) positioned adjacent the flat Venturi. The electromagnets generate an electromagnetic field to exert a force on the two-phase mixture in the direction of the flow. The flow stream then passes through a laminar flow grid (132) to remove turbulence, after which the oxygenated liquid is bottled at a bottling system (134).
