ABSTRACT:
A counter current supersaturation oxygenation system preferably includes a down flow tube, an upflow tube and a gas diffuser. The gas diffuser preferably includes a porous tube and a support frame. The porous tube is preferably wrapped in a spiral from a bottom of the support frame to a top of the support frame. A non-porous gas supply hose is connected to the porous tube. The gas diffuser is suspended inside the down flow tube at substantially a bottom thereof. One end of the upflow tube is connected to substantially a bottom of the down flow tube. A second embodiment of the counter current supersaturation oxygenation system preferably includes a down flow tube, the gas diffuser and a buoyant platform. A stream of liquid becomes oxygenated by passing down the down flow tube. The oxygenated liquid may flow up the upflow tube or down to any appropriate destination.
