A large vortex around the smallest particles
The Dreilägerbachtalsperre reservoir on the German-Belgian border near Roetgen has been supplying water to the district of Aachen since 1911, and takes advantage of water resources in the mountains of the nearby Eifel. From 2004, the connected drinking water treatment plant has routed raw water from the reservoir to a membrane filtration system. The ultrafiltration membranes have such small pores that they allow pure water to flow through, but retain all other substances in the water such as bacteria, viruses and proteins.
