The video shows the stages through which the wastewater passes through the FB180 module, becoming cleaner from stage to stage:

1. Inlet with IDM (magnetically induced flow measurement)
2. Electric slide valve for distributing the wastewater to other modules connected in pairs
3. Bio basin with fine-bubble membrane aerators and fixed-bed blocks (9 basins)
4. Aeration system with gate valve
5. Secondary clarifier with Mammut pumps
6. Recirculation of the biosludge
7. Drain box with serrated bar
8. Outlet pipe for the fully treated wastewater
