Compact biological wastewater treatment with integrated sedimentation
The ALMA BIO BBI combines an aerobic activation tank, fine-bubble aeration, sedimentation, and biomass recirculation into a compact system solution. Organic contents of the wastewater are biologically degraded, while the biomass is separated from the clarified water directly within the system and recirculated back into the activation stage.
Aerated Activated Sludge Tank
Microorganisms break down biologically available organic substances. Tube-membrane aerators supply the biomass with oxygen as needed.
Integrated Sedimentation
The sludge-water mixture enters the integrated sedimentation zone. There, the biomass settles, while the treated clear water flows out.
Internal Sludge Recirculation
The removed biomass is recirculated via Mammut pumps back into the aeration stage. This maintains a high concentration of active microorganisms in the system.
Benefits of ALMA BIO BBI
- Biology and Sedimentation in a Single System Depending on the project design, a separate secondary clarifier may not be necessary.
- Compact Plant Design Combining the process stages reduces interfaces, piping runs, and the space required.
- Energy-Efficient Fine-Bubble Aeration Tube-membrane aerators produce small air bubbles and promote efficient oxygen transfer.
- Effective Biomass Recirculation Internal recirculation keeps active biomass in the biological cycle and supports stable degradation rates.
- Automated Process Control Oxygen, flow, and COD measurements can be used to control plant operations as needed.
BBI or a conventional aeration system?
ALMA BIO BBI for compact applications
Suitable for small to medium wastewater volumes, limited installation space, and projects where a compact combination of biological treatment and sedimentation is desired.
Separate Activation and Secondary Clarification
This may be appropriate for very high flow rates, extensive nitrogen requirements, or more complex, multi-stage biological designs.
Membrane bioreactor for high-quality effluent
If the system must be largely free of solids or if subsequent water reuse is required, membrane separation may offer advantages over sedimentation. .
