Abstract
The pump energy requirements for the dissolving of a gas in a liquid are significantly reduced by injecting gas bubbles into a stream of said liquid at a relatively low pressure, utilizing a pressure head of liquid to increase the solubility of the gas in the liquid, and employing liquid stream velocities and gas-liquid contractor diameters and lengths, gas dispersion means and residence times such as to obtain a desired level of gas concentration in the liquid.
