ABSTRACT Apparatus for oxygenating a body of wastewater includes a chamber into which an oxygenating gas is introduced to form a gas space. A weir and a baffle are provided in the chamber to define a gravitational fall zone while a pump is provided for introducing wastewater into the chamber and for subjecting such wastewater to a gravitational fall over the weir and through the gas space to render the wastewater turbulent in the fall zone and thereby oxygenating such wastewater. A nozzle is also provided at the chamber outlet such that oxygenated wastewater is discharged into a body of wastewater under treatment.
