Multi Effect Distillation MED | Sulzer

The Multi Effect Distillation (MED) process is based on iterative evaporation-condensation processes in several stages under vacuum conditions, using residual steam from an adjacent power plant as heating media for evaporation. The main challenge for the pumps is low NPSH available. Typically end suction, low NPSH pumps are required.

Water Desalination Using Multi-stage Flash Distillation .

Desalination by multi-stage flash distillation is the commonly used method to produce fresh water from sea water. Most of the existing desalination plants use this method. This is a proven method and has been in service for the last three decades. In an MSF distillation sea water vaporisation takes place at low temperatures in vacuum. The vapours condense to form fresh water.
