Abstract
A method and apparatus creates gas-enriched fluid that is used to treat wastewater. In one embodiment, the wastewater is withdrawn from a supply of wastewater to be treated, and the wastewater is delivered in an atomized manner to a vessel pressurized with gas to form gas-enriched wastewater. The gas-enriched wastewater is then delivered to the supply of wastewater to be treated.
