MIDES project aimsto develop the World’s largest pilot plant demonstrator of an innovative and low-energy technology for drinking water production, using MDC technology as pre-treatment step for RO.
MIDES will integrate the MDC technology with commercialRO system (MDC-RO), achieving desalination at:
0.5 kWh·m-3 energy consumption75% lower energy cost
