Reverse osmosis is a water purification process. RO systems use partially permeable membranes to remove unwanted molecules, particles, salt, solutes or viruses from drinking water.
In reverse osmosis, applied pressure is used to overcome the osmotic pressure.
Reverse osmosis can remove many types of dissolved and suspended chemicals as well as biological substances (such as bacteria) from the water.
This system is used in both industrial processes and for the production of drinking water.
Reverse osmosis is best known for its use in purifying drinking water from seawater, removing the salt and other materials from the water molecules.
