Important results from the project
Projektet uppnådde i huvudsak sina mål genom genomförda genomförbarhetsstudier och experimentell validering av membranbaserad regnvattenuppsamling. Resultaten visar tydlig teknisk och ekonomisk potential samt identifierar centrala optimeringsparametrar. Projektet bidrog även med nya resultat kring kombinationen med PFAS‑rening och stärkte internationella samarbeten. Detta ger en stabil grund för fortsatt utveckling mot pilotskala och framtida tillämpningar.
Expected long term effects
The project is expected to contribute to the development of resource-efficient and decentralized water solutions in urban environments. The results provide a basis for further pilot-scale validation and possible integration of rainwater harvesting with removal of micropollutants such as PFAS. The work also strengthens international collaboration and supports continued research, innovation, and application in sustainable water management.
Approach and implementation
The project was carried out in two stages, focusing on feasibility studies followed by experimental validation. Technical, economic, and environmental aspects were analysed, and membranes were tested at MemLab (Lund university). The activities were relevant and largely completed according to plan. The collaboration worked well and was strengthened through the meeting in Singapore. The project also evolved by including PFAS-related studies, expanding the relevance of the results.
