Abstract

Method and apparatus for injecting gas into a liquid stream. The inside diameter of a conduit through which the liquid flows is reduced in a venturi section thereby creating a low pressure zone. A gas supply is exposed to the low pressure zone and gas from the gas supply is allowed to enter the liquid so as to mix therewith. The gas and liquid mixture is passed through an aerator to further reduce the size of the gas bubbles and thereby increase the surface area of the gas bubbles exposed to the liquid to enhance the reaction between the gas and the liquid.
