Approved and reliable concept for biological treatment plants (activated sludge)
Realisation as combined arrangement ("combi-plant") or independent placement of aeration tank (outer ring) and final clarifier (inner tank)
For the aeration and mixing within the activated sludge basin the following technical solutions are available:
- BSK^®-surface aerator (bridge installation)
- Membrane-aerators with additional submersed mixer
- "HyperClassic^®" or "Hyperjet"-systems with air dispersion
- Rotating brushes with/ without additional submersed mixers
Final clarifiers could be designed for gravity collecting (hopper shape) or mechanical scraping (flat bottom) of the sludge
