Abstract

An oxygen dissolution and bubble generator system (1) for dissolving oxygen and generating oxygen bubbles in an aqueous medium comprising an oxygen source such as an electrolyser stack (2) or a compressor; a pressure cylinder (7) for receiving the oxygen and an aqueous medium, and a pressurizing source which can be a pump (8) to increase the pressure in the pressure cylinder (7) to force dissolution of the oxygen in the aqueous medium. The invention also relates to a method of dissolving oxygen in an aqueous medium.
