1. An apparatus for treating a wastewater comprising:
- a gas-enrichment assembly adapted to receive the wastewater and a treatment gas, wherein the gas-enrichment assembly is configured to generate a gas-enriched fluid wherein the gas-enriched fluid is gas-supersaturated by the treatment gas; and
a delivery assembly coupled to the gas-enrichment assembly for receiving the gas-enriched fluid firm the gas-enrichment assembly and in fluid communication with the wastewater, the delivery assembly expelling the gas-enriched fluid in a substantially bubble-free manner into the wastewater and capable of raising the concentration of the treatment gas in the wastewater to hyperbaric levels.

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 In one embodiment, the wastewater is withdrawn from a supply of wastewater to be treated, and the wastewater is delivered in an atomized manner to a vessel pressurized with gas to form gas-enriched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.

8. A wastewater treatment facility comprising:
-
a gas-enrichment assembly adapted to receive a supply of wastewater and a supply of treatment gas, wherein the gas-enrichment assembly is configured to gas-enrich the wastewater to a desired content of the treatment gas in a substantially bubble free manner to generate a gas-enriched wastewater wherein the gas-enriched wastewater is gas-supersaturated by the treatment gas; and a delivery assembly coupled to the gas-enrichment assembly to receive the gas-enriched wastewater from the gas-enrichment assembly and in fluid communication with untreated wastewater that expels the gas-enriched wastewater into untreated wastewater in a substantially bubble-free manner and capable of raising the concentration of the treatment gas in the untreated wastewater to hyperbaric levels. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)
