Oxygenating apparatus, method for oxygenating water therewith, and applications thereof

A process for enriching a liquid with oxygen, which comprises the steps of:

• providing a sealed oxygen enriching space comprising a tubular passageway through which liquid flows on a continuous basis, said tubular passageway having turbulent mixers within;
• maintaining an oxygen pressure of at least 40 psi in the sealed oxygen enriching space;
• introducing the liquid through a liquid inlet into the sealed oxygen enriching space;
• introducing oxygen through an oxygen inlet into the sealed oxygen enriching space;
• passing the liquid and the oxygen through the turbulent mixer to thereby generate turbulence in the liquid and the oxygen to dissolve the oxygen into the liquid, wherein said step of providing a sealed oxygen enriching space comprising a tubular passageway comprises providing an enriching space having a venturi for introducing oxygen into the liquid before substantially dissolving the introduced oxygen in the liquid in said turbulent mixer;
• and
• recovering oxygen-enriched liquid having an oxygen content of at least 40 mg/l oxygen.
