The arguments for and against nitrogen removal have been penetrated. Special attention has been taken to the report by the panel of experts Naturvårdsverket (the Swedish Environmental Protection Board) has ordered. None of the arguments for nitrogen removal have been found to be valid for either Baltic Sea or the west coast.Bothnian Sea can be […]

Since January 1, 2006, new legislation from the European Union (among others; regulations EC 852/2004 and EC 882/2004) forces all food producers of the EU to include a hazard analysis based on the HACCP-principles in their internal control. HACCP (Hazard Analysis and Critical Control Point) is an international standard operated by the Codex Alimentarius Commission […]

River Vegeå drains parts of the agricultural lands in Southern Sweden. A preliminary characterisation of the water in Vegeå has been made using the guidelines developed in accordance with the Water Framework Directive.The work indicates that the guidelines are difficult to apply due to lack of data, which may cause a risk that the characterisation […]

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. Effects of separate means […]

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 […]
