State of the art in drinking water treatment by MF/UF in Germany—a survey among MF/UF plants

Membrane filtration is increasingly used for treatment in drinking water supply in Germany. MF and UF are applied processes to remove particles from raw waters of different origin. In the frame of a research project founded by the German Gas-and Waterworks Association (DVGW), a survey has been undertaken among a number of 83 plants that were put into operation until the end of 2006. The aim of the project was to gather technical data and practical experience in a database which should help in the design of future MF/UF plants. In the present paper the most important outcome of this project will be described.
