Reverse Osmosis Membrane

摘要

Reverse osmosis is a water purification technique that uses a partially permeable membrane to separate ions, and unwanted molecules from drinking water. In RO IS an applied strain is used to overcome osmotic strain, a colligative property this is driven through chemical potential differences of the solvent, a thermodynamic parameter. Reverse Osmosis (RO) can remove many types of dissolved and suspended chemical species in addition to biological and mainly bacteria from water, and is used in both industrial techniques and the production of potable water. The result is that the solute is retained on the pressurized side of the membrane and the pure solvent is allowed to pass to the opposite side.
