Development of progressive materials and processes for water and wastewater treatment involving the use of functional nanocomposites. The overall aim of NanoPurification was to develop innovative nanoscale substances and materials and see them transferred to the conventional water treatment and wastewater disposal sector. In this context, a water treatment system was developed combining nanoscale composite microfilters with UV decontamination in order to create a highly efficient and multifunctional solution. EnviroChemie implemented a pilot application in the industrial water sector, in which new ground was broken in the manufacture of microfilters as well as in the use of UV LEDs.
