Reverse osmosis employs a membrane-based technique that utilizes the pressure gradient to separate the solvent from a solution. By applying pressure to the solvent on one side of the membrane, it surpasses the osmotic pressure, resulting in the solvent's reverse permeation in the direction of natural infiltration. As a consequence, the low-pressure side obtains the permeated solution, while the high-pressure side obtains the concentrated solution. The reverse permeable membrane effectively intercepts diverse inorganic ions, colloidal substances, and macro-molecular solutes in water, employing a straightforward process and exhibiting low energy consumption. Consequently, this technology has experienced rapid development.
Presently, reverse osmosis finds wide application in the purification of drinking water, desalination of seawater and brackish water, and in combination with ion exchange to produce high-purity water.
