Multiple-effect humidification

Water desalination

Methods

Distillation
- Multi-stage flash distillation (MSF)
- Multiple-effect distillation (MED)
- Vapor-compression (VC)
Ion exchange
Membrane processes
- Electrodialysis reversal (EDR)
- Reverse osmosis (RO)
- Nanofiltration (NF)
- Membrane distillation (MD)
- Forward osmosis (FO)
Freezing desalination
Geothermal desalination
Solar desalination
- Solar humidification–dehumidification (HDH)
- Multiple-effect humidification (MEH)
- Seawater greenhouse
Methane hydrate crystallization
High grade water recycling
Wave-powered desalination

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]
