Today, reverse osmosis is the most technologically advanced and least expensive method of water purification from salts or desalination.
One of the significant advantages of reverse osmosis is that it causes the least environmental damage compared to other methods of water desalination.
The reverse osmosis method is based on the use of a semi-permeable membrane that allows water to pass through and retains 99% of the salts. The driving force behind reverse osmosis is the pressure applied to the membrane, which affects the resolution. The pressure is used to remove salts, organic matter, bacteria and viruses.
