Model R OXIGEST® for Municipal / Sanitary Wastewater

Proven in hundreds of installations, the Model R OXIGEST® treatment system provides stable operation and flexible process options for sanitary and large flow wastewater applications. The OXIGEST® design encompasses complete aeration, clarification and advanced treatment in concentric tankage while allowing these unit processes to be individually separated and controlled. Its concentric tankage maximizes space efficiency in its footprint, thereby preserving precious facility land for other key plant operations.

Multiple aeration zones can be employed to provide specific activated sludge processes for desired treatment levels, including BNR processes like AOAO and Bardenpho, multi-stage aeration, complete mixed, plug-flow and nitrification/denitrification. Integral treatment process steps can include grit removal, flow equalization, nitrification, denitrification, re-aeration, tertiary filtration, chlorination, dechlorination, sludge storage, or other specialized treatment. Systems can be designed for nutrient removal, water reuse and direct or indirect discharge. The OXIGEST® is equipped with high performance components that offer advanced process control and automation throughout the plant’s operation.
