Multi Effect Distillation

Desalting water through evaporation techniques

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. For larger capacities axial split casing pumps are also used.
