About this facility
MED is a pilot plant based on multi-effect distillation, with 14 vertically stacked effects in a forward-feed configuration. Evaporation and condensation stages desalinate water at a top brine temperature of approximately 70 °C. At design conditions, the process requires approximately 200 kW of thermal power to produce 3 m³ of desalinated water per hour, with a recovery ratio of 37.5%. Solar heat can be supplied by the AQUASOL-II flat-plate collector field or, for MED processes coupled with an absorption heat pump, by a small-aperture parabolic-trough field.
