Operations and Control in Wastewater Treatment - Some Swedish Experiences

New demands on nutrient removal in Swedish wastewater treatment plants have motivated new research and development activities. In this paper some ideas behind a new Swedish government research program are described, and an outline of current research activities and programs is made. Operational problems are emphasized, and their interdisciplinary character is recognized. Consequently a research team has been formed in Lund with active participation from applied microbiology, process technology, control engineering and working environment technology, in cooperation with the sewage works in Malmo
