The world needs more drinking water, without damaging ecosystems, and the sea is one possible source. The NAWADES project, in which LEITAT participates, is developing a self-cleaning filter membrane for desalination plants that cuts their energy use, waste and maintenance costs compared to those of existing filters.
The European Commission has published an article about the NAWADES project on the Horizon 2020 website.
By keeping the filters clean and clear of blockages, treatment plants do not need such high water pressure to remove salt from water, thus saving energy. The self-cleaning technology also means that plant operators can reduce the amount of polluting chemicals needed to clean filters and can cut maintenance costs.
