Optimizing biodisk WWTPs with our lamella clarifier
The community of communes was experiencing technical difficulties in its rotating biological contactor (RBC) wastewater treatment plant, related to the limited capacities of the two drum filters used in the biological treatment. This configuration did not adequately meet regulatory requirements for TSS and COD, resulting in frequent exceedances and regular non-compliance with established standards.

How to Optimize a Rotating Biological Contactor Plant with a Lamella Settler?
To improve its efficiency, the installation of a lamella settler has reduced the load before final filtration. Placed after the rotating biological contactors, it captures residual particles and manages flow variations. Thus, the water is cleaner and complies with standards, optimizing the treatment of pollution peaks to ensure consistent performance without oversizing the installation.
Here are the key elements of this solution:
- Load Peak Management: The lamella settler, added after the rotating biological contactors, captures residual particles and reduces the load before filtration
- TSS Reduction: Thanks to sedimentation, the system maintains levels compliant with standards, even during flow peaks.
- Compact Installation: The system is designed to be modular and easily integrate into existing structures, minimizing space requirements.
- Efficient and Adaptable Solution: The installation ensures stable performance, avoids equipment oversizing, and guarantees discharges compliant with standards.
Increased Efficiency of Rotating Biological Contactors Thanks to Lamella Settlers
Lamella Settler: A Solution to Optimize Rotating Biological Contactor Plants
The installation of a lamella settler has significantly improved water treatment in rotating biological contactor plants. Downstream of the RBCs, the settler effectively captures residual particles, achieving reduction levels compliant with strict TSS and BOD5 standards. Moreover, its compact design facilitates integration into existing structures, thus reducing required space and installation costs. This optimization also allows for more stable management of pollution peaks, ensuring reliable and sustainable treatment.
Cost Reduction and Efficiency Improvement
Precise sizing adjustment has simplified load management without oversizing the installation, which has reduced operational costs. This flexible and high-performance solution ensures consistent water quality and paves the way for future expansions to accommodate plant growth.
