How it works

1. Wastewater treatment
The wastewater arrives directly in the biological zone without the need for pumping processes. Aeration of the entire container leads to immediate wastewater activation. The microorganisms begin the biological cleaning process without delay.
2. Settling phase
Aeration is interrupted by the control unit, the activated sludge sinks to the bottom. A clear water zone develops in the upper part of the container.
3. Clear water extraction
The treated clear water is extracted from the system and the cleaning process can begin once more.
Treatment performance
| Biological Oxygen Demand (BOD) | Suspended Solids (SS) | Ammonia (NH₄-N) | Phosphate (Ptot) | Nitrate (Ntot) |
|---|---|---|---|---|
| 7 mg/l (98.0%) | 14 mg/l (96.3%) | 0.5 mg/l (98.3%) | 1.6 mg/l (80.2%) | 7.9 mg/l (87.0%) |
