The purification of seawater can be achieved in a number of ways. Desalination is one of them and it involves extracting salts and minerals from saline, salt or seawater. It is a water treatment purification process that is used extensively around the World and its use is increasing as population growth, industrialisation and climate change impact the demands for clean water suitable for drinking purposes.
Salt water is commonly desalinated in order to produce purified water that is suitable for humans to drink (potable water) or use for the irrigation of crops. When salt water is desalinated it produces fresh water with salt as a by-product.
