Abstract:
An apparatus (10) for the introduction of oxygen into a liquid (14) comprises a pump (12) for supplying liquid to a mixing device (18) positioned at or near the surface S of the liquid so as to avoid problems associated with hydrostatic head and a PSA device (34) for providing oxygen at an unboosted pressure to the mixing device (18). The mixing device (18) being designed for utilising fluid energy to assist with the mixing of oxygen with the liquid.

Abstract:
An apparatus (10) for dissolving a gas into a fluid which may contain at least one dissolved gas. The apparatus (10) includes a first vertically oriented tube (2) defining a first inner space (32) and a second vertically oriented tube (12). The space between the first and second tubes is referred to as the second inner space (40). The gas is introduced through an inlet (18) into the second inner space (40). The apparatus (10) includes an acceleration device (20) for accelerating the flow of fluid through the second inner space (40). The apparatus includes a helix-shaped bubble harvester (22) which removes fugitive (undissolved) bubbles from the fluid flow and returns them to the second inner space (40) to increase the probability that those bubbles will be dissolved into the fluid.
Abstract:
In order to dissolve a gas such as oxygen in a liquid, typically aqueous, a steam of liquid is taken from tank 2 by a pump 20 and pressurised thereby. Oxygen is introduced into the stream via a conduit 18 upstream of a venturi 10. The resulting mixture of oxygen bubbles and liquid is accelerated from a sub-sonic to a super-sonic velocity as it flows through the venturi 20. The resultant shockwave is effective to reduce the size of the bubbles. The stream of liquid carrying oxygen bubbles dispersed therein is then transported at sub-sonic velocity along the conduit 12 to a sparge pipe 14 through which it is introduced into the main volume 4 of liquid into the tank 2. As the liquid passes through the orifices of the sparge pipe 14 so it is again accelerated to a super-sonic velocity and another shockwave is created thereby causing the bubbles to reduce in size such that they readily dissolve in or are consumed by the main volume of liquid.
