The EU Water Framework directive requires planning on river basin basis. Different means affect different basins in different ways. In this study it is shown how small basins can be characterized and how a problem analysis can be done with respect to water requirement, water quality, land use and concentrated activities.

Constructed wetlands (CWs) and filterbeds are used throughout the world to treat wastewater. For these systems, selection of a suitable filter material for P sorption is essential, as well as design criteria that enables an efficient treatment. Batch experiments have been the main tool for obtaining maximum P sorption capacities for potential filter materials. They […]
