For decades, drinking water and water for domestic use have been obtained through traditional thermal methods of sea water desalination: The sea water is heated until it reaches boiling point and evaporates, at which point the hot steam is cooled and condensed into fresh water. However, this process has some major disadvantages, notably the fact that it uses such large amounts of energy. Despite the use of various energy recovery technologies, it is often not financially viable – especially in countries that lack energy resources.
Ultrafiltration and reverse osmosis
The best alternative for future applications is a combination of ultrafiltration and reverse osmosis. The initial cleaning of the sea water is performed efficiently by ultrafiltration, while the actual desalination of the water is achieved through reverse osmosis.
