Product Description

                                   Aerobic Systems

Treatment process for raw wastewater or further polishing of pretreated wastewater

Product Description

The whole Aeration system included the aerator(bubble diffuser) gas distribution pipes, tees, crosses, elbows, regulators, connectors, cleaning devices, and other components. Usually, gas distribution pipelines are the usual circular arrangement, diffuser quantity is according to the air capacity and ponds size. The diffuser and gas distribution pipelines use G3 / 4 threaded connection, the base is an inner thread (fixed in the pipeline), the diffuser is externally threaded.

Detailed Photos

Aerobic treatment is a biological wastewater treatment process that takes place in the presence of oxygen. Aerobic biomass converts organics in the wastewater into carbon dioxide and new biomass.

Evoqua offers aerobic treatment systems for both municipal and industrial facilities looking to treat raw wastewater and/or polish anaerobically pretreated wastewater. Ultimately, further reducing biochemical oxygen demand (BOD), total suspended solids (TSS), nitrogen, and phosphorus. Aerobic treatment systems can also be used specifically to remove nitrogen and phosphorus in the process known as biological nutrient removal (BNR).
