Oxidation ditch

The OxyStream™ Oxidation Ditch from WesTech Engineering is ideal for biological wastewater treatment applications. It combines vertically-mounted, low-speed surface aerators with an oxidation ditch design to maximize oxygen transfer efficiency while maintaining high 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.
