Seawater Desalination Plants

Doosan Heavy Industries and Construction has secured the three most popular desalination technologies, namely, MSF (Multi-Stage Flash), MED (Multi-Effect Distillation) and RO (Reverse Osmosis), and established supply records in all three fields. The company has also taken the number one spot in the large-capacity desalination plant market, and successfully supplied the world's first hybrid plant, equipped with both MSF and RO methods, under the Fujairah Hybrid desalination project for UAE.

Multi-Stage Flash (MSF)

Multi-Stage Flash (MSF)

With the MSF (Multi-Stage Flash) method, sea water flows through a multi-level heat exchange system, is heated with steam from the power generating plant until evaporation, and is then condensed on the outside of pipes through which cold seawater flows. This method is popular with large capacity desalination plants.

Multi-Effect Distillation (MED)

Multi-Effect Distillation (MED)

MED (Multi-Effect Distillation) is similar to MSF, but only makes use of devices called Effect instead of “Stage” from MSF. The MED method has the advantage of reducing energy consumption if applied with dump heat, and is mostly used for medium-capacity desalination plants.

Reverse Osmosis (RO)

Reverse Osmosis (RO)

As the name suggests, pressure is applied to seawater in order to separate substances like water and salt and thereby produce fresh water. Its relatively easy operation and low energy consumption make it ideal for all capacities - small, medium and large plants.
