Commercial RO Membrane

Reverse osmosis (RO) is a water purification technology that uses a semipermeable membrane to remove ions, moleculesand 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. Reverse osmosis can remove many types of dissolved and suspended species from water, including bacteria, and is used in both industrial processes and the production of potable water.
