Seawater desalination is how we remove salt and impurities from seawater to produce drinking water.
Our desalination plants use a reverse osmosis process. Seawater is pumped into the desalination plant from the Indian Ocean and passes through pre-treatment filtration to remove most particles. The filtered seawater is then forced under pressure through special membranes. The osmosis process that occurs in nature is reversed. The pores in the membranes are so tiny that salt, bacteria, viruses and impurities separate from the seawater.
