Reverse osmosis - Wikipedia
Reverse osmosis (RO) is a water purifiion process that uses a partially permeable merane to remove ions, unwanted molecules and larger particles from drinking water. In reverse osmosis, an applied pressure is used to overcome osmotic pressure, a colligative property that is driven by chemical potential differences of the solvent, a thermodynamic parameter.
