Reverse osmosis - Wikipedia
Reverse osmosis - Wikipedia

Reverse osmosis, (,RO,) is a water purification process that uses a partially permeable ,membrane, to separate 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.
