Reverse-osmosis meaning
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.
noun
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.
noun
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.
noun
A method of producing pure water by forcing saline or impure water through a semipermeable membrane across which salts or impurities cannot pass. Reverse osmosis is used for water filtration, for desalinization of seawater, and in kidney dialysis machines.
