regulation of sequenced aeration for activated sludge – Greenbass™
The GreenbassTM is a sequenced aeration regulation process for activated sludge, fine-tuning the air-flow supplied to the biological treatment process depending on the pollution load. The key to the GreenbassTM control mechanism is that it is based on the fluctuating concentration of nitrogen’s reduced form (ammonium) and oxidized form (nitrate).
The advanced regulation program contains a patented algorithm which constantly recalculates the useful quantity of air as a function of the biological activity.
key figures
- Up to 15 % energy saving
- Reduction of 20 to 30 % pf the air flow supplied for a similar quality
