As a natural consequence of our interest in biological and membrane processes, we also direct efforts at the development of membrane bioreactors (MBR) for wastewater treatment. Besides optimisation of MBR processes, we also investigate membrane fouling, nutrient removal and sludge characterisation. We co-operate with the Centre of Competence for Water Berlin, Berlin Waterworks, Veolia Water, A3 Water Solutions GmbH and others.
