Reverse osmosis is a way to get clean water out of dirty water or salt water by forcing water under pressure through a membrane.
An example of reverse osmosis is the process of filtering polluted water under pressure.
a method of extracting essentially pure, fresh water from polluted or salt water by forcing the water under pressure against a semipermeable membrane, which passes the pure water molecules and filters out salts and and other dissolved impurities
A process by which a solvent such as water is purified of solutes by being forced through a semipermeable membrane through which the solvent, but not the solutes, can pass.
