Azenit™ - A20
Biological treatment of wastewater by activated sludge
Biological treatment of wastewaters for nitrogen and/or phosphorus removal by activated sludge.
Applications
Azenit achieves complete control of nitrification and denitrification within a reactor, where sequential aeration operation mode combined with a bacterial selector at the inlet are provided.
As nitrogen, phosphorus, COD, BOD and SS pollutants are removed simultaneously, due to a control of oxygen consumption, Azenit™ is proposed in a sigle tank configuration.
Main configurations
Azenit™ can be offered in the following categories
- Azenit™ : for nitrogen removal.
- Azenit™ P : for simultaneous nitrogen and phosphorus removal.
- Azenit™ C+ : with methanol added in a specific tank for low TN requirements or for low COD/N ratios of the influent.
- Azenit™ BIO+ : for nitrogen load fluctuations (storm flows, seasonal variations e.g. tourism), automatically operates in two configurations : one for low load conditions, the other for high load conditions.
- Azenit™ C-S : for seasonal industrial influents, highly loaded in carbon, with high bulking risk.
