MED : Multiple Effect Distillation

Processes for Sea Water Desalination

Veolia Water Technologies is the world leader in sea water desalination through low temperature distillation processes such as :

Multiple Effet Distillation (MED)

Multiple Effet Distillation (MED)

  • Multiple Effet Distillation (MED)
  • Multiple Effect Distillation with Thermal Vapour Compression (MED-TVC)
  • Multiple Effect Distillation with Mechanical Vapour Compression (MED-MVC)

A Multi Effect Desalination MED unit is an evaporator where sea water is evaporated in one or more ( up to 14 ) evaporation stages at low temperature ( < 70°C ) in order to produce clean distillate water.

MED process is designed to produce distilled water with waste heat from power production or chemical processes, and to produce potable water.
