Anoxic selectors
Key to effective denitrification

Use innovative technology to optimize anaerobic processes — improve biological purification and reduce operating costs.

Application: anoxic selectors

Effective denitrification with economical mixing

Anoxic selectors facilitate denitrification in activated sludge processes for municipal or industrial wastewater treatment plants to remove nitrate prior to discharge into the environment. For optimal denitrification, it is vital to provide proper mixing of wastewater flow and return streams, maintain solids in suspension, and not impart measurable oxygen.

A BioMix™ Compressed Gas Mixing System accomplishes these objectives using a fraction of the energy required by mechanical mixers.

Additionally, the BioCycle-ENR Activated Sludge Process and FlexZone™ Adaptive Process Volume System are ideally suited for municipal and industrial secondary treatment processes with anoxic selectors. The technologies are extremely effective for plants that are underloaded compared to design, or plants with wide diurnal variations.
