a technique for purifying water, in which pressure is applied to force liquid through a semipermeable membrane in the opposite direction to that in normal osmosis
reverse osmosis in American English
a method of extracting essentially pure, fresh water from polluted or salt water by forcing the water under pressure against a semipermeable membrane, whichpasses the pure water molecules and filters out salts and and other dissolved impurities

(Chemical Engineering: General)
Reverse osmosis is a method of purifying water, in which pressure is used to force a more concentrated liquid through a semipermeable membrane to a less concentrated liquid.
In reverse osmosis, an applied pressure gradient greater than the osmotic pressure ensures flow fromthe more concentrated to the less concentrated solution.
Reverse osmosis uses high pressure to force saltwater through a semipermeable membrane, and thisseparates the salt from the water.
