Researchers from the University of Alicante’s research group in applied electrochemistry and electrocatalysis have developed a standalone system for desalinating and treating water through electrodialysis. The system is directly powered by solar energy and can be applied in off-grid areas. The research group has a pilot and demonstration plant able to generate a cubic metre of drinking water every day. What is new about this UA-developed technology is that all electricity supplied to this system comes from a photovoltaic solar field. Additionally, it makes the most of the maximum energy supplied by panels when exposed to sunlight. This technique “can only be employed to treat water with a salt content exceeding that tolerated for human consumption or irrigation.
