The decentral and mobile water treatment system reacts to the lack of clean drinking water especially in the developing countries.
The originated system consists of two units: the WaterDonut and the UltraPipe. Both parts are able to work on their own, but also together. The WaterDonut uses the disinfecting influence of the sun - called SODIS-effect. It is constructed to last about 10 years. When there is no sun shining, the UltraPipe filters the water through a pressure driven membrane independent from the weather.
