When the same volume of dilute solution (e.g., fresh water) and concentrated solution (e.g., saline) is placed on each side of the semi-permeable membrane, the solvent in the dilute solution will naturally flow through the semi-permeable membrane spontaneously to the concentrated solution side, a phenomenon known as osmosis. When the osmosis reaches the equilibrium, the liquid level of the concentrated solution side is higher than the liquid level of the dilute solution by a certain height, namely, a pressure difference is formed, and the pressure difference is the osmotic pressure. The magnitude of the osmotic pressure depends on the inherent properties of the solution, i.e. on the type, concentration and temperature of the concentrated solution and not on the properties of the semipermeable membrane. If a pressure greater than the osmotic pressure is applied to the concentrated solution side, the solvent will flow in the opposite direction to the original direction of osmosis, and will start to flow from the concentrated solution to the dilute solution side, a process known as reverse osmosis. Reverse osmosis, which is a reverse migration motion of osmosis, is a separation method of separating solute from solvent in solution by selective interception of semipermeable membrane under pressure driving, and is widely used for purification and concentration of various liquids, wherein the most common application example is in water treatment process, impurities such as inorganic ions, bacteria, viruses, organic matters and colloids in raw water are removed by reverse osmosis technology to obtain high-quality purified water.
