ABSTRACT:
An improved apparatus for the introduction of a gas into a liquid comprising a mixing device formed by a first generally convergent section and a second generally divergent section, said first section having a narrow outlet end of smaller diameter than an inlet end of said second section and extending thereinto so as to form an annular gap therebetween, and supply means for supplying said gas to said annular gap so as to facilitate the mixing of said gas with any liquid passing therethrough. The mixing device is preferably positioned at or near the surface of the liquid so as to avoid problems associated with hydrostatic head. The apparatus is advantageous in the treatment of a liquid with oxygen which is preferably generated by a Pressure Swing Adsorption device.
