SSB® Process – How it works

STABI-KOM efficiency through the SSB® process: All purification steps take place in a compact tank with two hydraulically connected treatment chambers.

Aeration phase

Inflow enters chamber one: SSB® aeration immediately starts biological treatment. Coarse solids remain behind, water flows to the second chamber.

Settling phase

After aeration follows the settling phase: Activated sludge sinks to the bottom, clear water stands at the top. Some sludge flows back into the first chamber.

Discharge phase

The clear, treated wastewater at the top is then conveyed to the outlet using compressed air. After this phase, the next treatment cycle starts.
