Description:... In 1991 the EU announced a directive regarding urban wastewater treatment. Its objective was to have wastewater collection and treatment for all settlements and nutrient removal for all sensitive areas. These measures needed to be implemented in a short time period, before 2000. The directive resulted in a boost in the applied research towards wastewater treatment and a large investment in new facilities. The 2000 Aquatech conference therefore aimed at evaluating how this directive (or similar directives worldwide) was implemented. The 25 papers selected for these proceedings give an overview of the policies related to nutrient removal in a number of regions. They show the differences in approach and in the results of measures taken. New processes have been developed and existing treatment plants have been upgraded for nutrient removal. Several of these new processes are described together with a number of examples of upgrading of existing facilities. These proceedings provide wastewater engineers, policy-makers and managers with a state-of-the-art view of the approaches that can solve eutrophication problems and minimise the impacts on society and the environment.
