Abstract

The invention relates to a system for treating liquid such as aqueous liquor with a gas that is sparingly soluble therein by introducing the gas into a pressurized stream of the liquid at a sufficient rate to dissolve some of the gas in the stream and additionally to form finely dispersed bubbles of undissolved gas which are carried within the stream. The velocity of the stream is sufficiently high to ensure that the bubbles do not combine to form a discrete vapor phase. The stream is introduced into a volume of the liquid under turbulent conditions so that the bubbles of undissolved gas are broken into even finer bubbles which either dissolve or are consumed in the liquid volume.
