Wupperverband is using lamella separators for the upgrading of its Kohlfurth sewage treatment plant that is currently in progress. The lamellae positioned at the outlet of the biological treatment stage already remove part of the biomass in the activation basin and prevent it from reaching the final clarification stage.

This article gives an overview of the separation performance achieved.
