Rapid population growth, water pollution and increased drought are the main reasons for the need for seawater augmentation, increasing the consumption of high quality water resources.
Investments are made to provide drinking and utility water from sea water, especially in regions with water scarcity and coastal areas. Reverse osmosis systems for desalination are the most widely used technology.
The interest in seawater treatment has increased in heavy industries such as iron and steel, power plants, chemical industries and refineries.
Seawater treatment is most commonly needed in arid regions. Therefore, the greatest need and investment is in the Middle East and North Africa.
