OxyStream™ Oxidation Ditch

OxyStream™ Oxidation Ditch

The OxyStream™ Oxidation Ditch from WesTech Engineering has proven to be the ideal equipment 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 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. Above all, the OxyStream™ Oxidation Ditch provides energy savings and produces predictable, high-quality effluent.

ABOUT AERATION

 

A common first step in the secondary treatment process is to send wastewater to an aeration tank. In an aeration tank, bacterium is used to effectively break down pollutants into less harmful components. Wastewater aeration provides the appropriate oxygen level so that aerobic bacteria can thrive in degrading pollutants such as iron and manganese as part of the wastewater treatment process. Aeration can also be used to destroy anaerobic bacteria that perish in the presence of oxygen. Aerobes that can break down pollutants 10-100 times faster than anaerobes are used most frequently.

Aeration is also used to improve waste lagoons and other waterways such as lakes and reservoirs where oxygen deficiency contributes to taste, odor and pollutant problems. Equipment used for wastewater aeration includes low cascades, jet fountains, spray nozzles, blowers, submerged perforated pipe and porous plates or tubes. Whether the water is thrown into the air via a fountain or diffused by air bubbles being blown or drawn into the wastewater in an aeration tank, aeration works by increasing the area of contact between the oxygen in the air and water.

The most common wastewater aeration process in use today is the air diffusion process, where air is introduced from blowers through diffusion tubes suspended in a spiral flow tank, or in some cases, through diffuser plates in the bottom of the aeration tanks.
