SHARE

As the name suggests, pressure is applied to push seawater through a semi-permeable membrane in order to remove contaminants like salt from the water and thereby produce fresh water. Being relatively easy-to-operate and boasting of low-energy consumption, this technology is ideal for plants of any capacity - small, medium or large-capacity plants.

Multi-Stage Flash (MSF)

With the MSF (Multi-Stage Flash) method, the feed seawater flows through a number of heat exchangers (“stages”), gets heated by the steam generated from the power plant until becoming water vapor, which in turn is condensed on the outside surface of the tubes through which cold seawater flows.

Multi-Effect Distillation (MED)
MED (Multi-Effect Distillation), similar to the MSF, is a desalination technology that involves an evaporation process going through a series of chambers (also known as “effects”), with each successive chamber operating at a progressively lower pressure. The MED method has the advantage of reducing energy consumption if applied with dump heat and is mostly used for medium-capacity desalination
