Aerobic Granular Wastewater Treatment - A New Technology

Aerobic Granular Wastewater Treatment - A New Technology

Aerobic Granule Sequencing Batch Reactors claim to simultaneously oxidize organics, oxidize ammonia, reduce nitrate/nitrite, and remove soluble phosphate.

With new permits requiring the removal of more nitrate/nitrite and phosphorus, wastewater treatment systems are becoming more complex with anaerobic/ass erobic/anoxic zones that frequently require separate reactors.

The footprint and operational challenges have become larger than seen with conventional activated sludge treatment of 30 years ago.

Among the new trends in advanced wastewater treatment, Aerobic Granule Sequencing Batch Reactors claim to simultaneously oxidize organics, oxidize ammonia, reduce nitrate/nitrite, and remove soluble phosphate. All while not requiring secondary clarifiers to settling biological solids.
