Background technique

Reverse osmosis, also known as reverse osmosis, is a membrane separation operation that uses pressure difference as a driving force to separate solvent from a solution. Apply pressure to the material liquid on one side of the membrane. When the pressure exceeds its osmotic pressure, the solvent will reverse osmosis in the direction of natural penetration. As a result, the permeated solvent is obtained on the low-pressure side of the membrane, which is the permeate; and the concentrated solution is obtained on the high-pressure side, which is the concentrated solution. If reverse osmosis is used to treat seawater, fresh water will be obtained on the low-pressure side of the membrane, and brine will be obtained on the high-pressure side.
