    • Multiple-effect distillation (MED)
    • Vapor-compression (VC)
  • Ion exchange
  • Membrane processes
    • Electrodialysis reversal (EDR)

Multiple-effect humidification (MEH) is a method used for thermal desalination of sea water. It uses multiple evaporation–condensation cycles at separate temperature levels to minimize the total energy consumption of solar humidification processes.[1]
