Uranium occurrence in natural water sources represents a threat to human health due to its chemitoxicity, leading public health agencies to set maximum acceptable concentration guidelines as low as 30 μg/L for drinking water. Uranium contamination of groundwater results from the natural dissolution of mineral formations and anthropogenic activities, such as mining. This is the case of the old Krunkelbach pit near the municipality Menzenschwand in the Black Forest, where a spring water conduit has uranium concentration above the guideline. Photovoltaic-powered nanofiltration (PV-NF) is a promising technology for the provision of drinking water in, for example, off-grid rural areas in developing countries. Removal of uranium from contaminated groundwater using PV-NF could increase access to safe drinking water by enabling consumption of currently unutilized water sources, thereby contributing to the realization of United Nations Sustainable Development Goal (SDG) 6: ensure availability and sustainable management of water and sanitation for all. This project aims to evaluate the removal of uranium from real water sources during field experiments using a mobile pilot-scale PV-NF system.

Specific project tasks will include:

• Conduct field-based experiments for the removal of uranium from water using a pilot-scale photovoltaic-powered nanofiltration system.
• Collect water samples for water analysis using IAMT facilities, including uranium analysis using inductively coupled plasma mass spectrometry (ICP-MS).
• Analyse experimental data and contribute to writing a joint research publication (in English).

KIT is one of the biggest research institutions worldwide and has access to state-of-the-art research facilities. This project is hosted by the relatively new Institute for Advanced Membrane Technology (IAMT) in new laboratories and state-of-the-art equipment. IAMT is part of the Division Earth and Environment at KIT and the Faculty of Chemical and Process Engineering.
