Evaluating stormwater treatment for non-potable purpose using SiC membranes in Sweden

This study explores the potential for stormwater reuse to reduce potable water consumption for toilet flushing and laundry. A pilot project utilizing silicon carbide (SiC) membranes in Lund achieved significant reductions in contaminants, with permeate meeting EU standards for non-potable applications.A permanent (SiC) membrane installation in Malmö demonstrated a 38% reduction in potable water use, saving 250,000 liters for toilet flushing and laundry. Ongoing analysis of 57 water parameters supports the concept as a sustainable method to reduce water consumption by over 30% in urban conditions.Acknowledgement: This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No 869496.
