### Reverse Osmosis

**Reverse Osmosis** is a water purification process that uses a semipermeable membrane and the application of high pressure to separate salt ions, small molecules and colloidal particles from water sources such as seawater, brackish water and wastewater to obtain clean and potable water. Due to its overall economics and ease of operation, it is the frontrunner in desalination.
