Sea Water

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.
Compared to conventional treatment technologies such as sand filtration, UF technology produces outstanding water quality and consistently high filtrate quality, regardless of any changes in raw water properties due to seasonal variations (storms, algae bloom, etc.) or other factors.

Benefits of inge® ultrafiltration for sea water treatment:

  • Maximum stability – zero fiber breakage – minimal risk of biofouling
  • Consistently high level of filtrate quality
  • Tolerance over a wide pH range – exceptionally easy to clean
