A process by which a solvent passes through a porous membrane in the direction opposite to that for natural osmosis when subjected to a hydrostatic pressure greater than the osmotic pressure.
〔化〕反渗透，逆向渗透
Example sentencesExamples
A more efficient desalination technique is reverse osmosis where, by applying pressure to the seawater, the water moves across a semi-permeable membrane, leaving the dissolved salt behind.
In addition, the most common membranes used in reverse osmosis units are subject to decay and failure and must be replaced periodically.
An increasingly popular process, reverse osmosis, essentially filters water at the molecular level, by forcing it through a membrane.
They submit it to such modern technological processes as ion exchange and reverse osmosis together with super-efficient filtration and evaporators to produce what is in effect a concentrated invert sugar solution from grape juice.
Advances in processing technology, including ultrafiltration, microfiltration, reverse osmosis, and ion-exchange have resulted in development of several different finished whey products.
