ABSTRACT:
An absorber for increasing the concentration of oxygen in a solution has a pressure chamber therein which receives oxygen under pressure as well as a liquid to be oxygenated within an upper portion thereof. A shaft on which a turbine blade agitator is mounted is located in the upper portion of the chamber. The shaft is driven rotationally by a motor through a rotary seal in the pressure chamber cover. A baffle plate is mounted within the pressure chamber to define a lower portion therebeneath, which is in communication with the upper portion, but isolated from the agitation in the upper portion. The oxygen-liquid solution which drains into the lower portion is subsaturated and relatively quiescent, so that large oxygen bubbles therein disengage and rise into the upper portion, and entrained small bubbles therein dissolve in the subsaturated oxygen-liquid solution. Consequently, substantially all of the oxygen contained in the oxygen-liquid mixture is in solution when the oxygen-liquid solution is removed from the lower chamber.
