反滲透是九十年代發(fā)展起來(lái)的一種膜分離技術(shù)，它主要利用半透膜的滲透原理，通過(guò)一定和方式給它施加一種壓力，反于自然滲透方向的力，使?jié)馊芤褐械乃蛳∪芤褐袧B透，這種方式稱為反滲透。由反滲透元件組成的裝置稱為反滲透裝置。
Reverse osmosis is a
kind of membrane separation techniques which was
developed in 1970s it mainly used the osmosis
principle of the semipermeable membrane, and
brings a kind of pressure to it in a certain
way, opposite to the force in natural osmosis
direction, then the water in the strong solution
osmosizes into thin solution, this is reverse
osmosis. The unit which is made up of reverse
osmosis components is reverse osmosis unit.
