The OxyStream oxidation ditch from WesTech Engineering has proven to be ideal for biological wastewater treatment applications throughout the world. It combines vertically mounted low-speed surface aerators with an oxidation ditch design to maximize oxygen transfer efficiency while maintaining flexibility for power turndown. In addition, the OxyStream has greater side water depths and requires fewer 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. Above all, the OxyStream oxidation ditch provides energy savings and produces predictable, high-quality effluent.
