OxyStream™ Oxidation Ditch

The OxyStream™ oxidation ditch is a modified, activated sludge, biological treatment process that removes
biodegradable organics from wastewater. The OxyStream™
process combines vertically mounted, low-speed surface
aerators with a continuous racetrack layout to maximize
oxygen transfer efficiency while maintaining the greatest
flexibility for power turndown.
In addition, the OxyStream™ has greater side water depths
and fewer required aerators than a conventional brush rotor
or disc rotor oxidation ditch. The vertical slow-speed surface
aerator eliminates maintenance-prone horizontal shafts,
pillow-block bearings, and drive units near the water surface The Advanced OxyStream Control System or AOCS which uses a PLC and expandable control logic to adjust aerators, adjacent basin mixers, pumps, valve actuators, etc
