Accepted Answer

Reverse Osmosis. The process of transforming salty water into pure water is called Reverse Osmosis (RO). In reverse osmosis process, water containing dissolved salt molecules is forced through a semi-permeable membrane (essentially a filter) in which the larger salt molecules do not get through the membrane holes but the smaller water molecules do it. Another process to transform salty water to pure water is desalination. It is mainly used for large amount of drinking water.
