Osmosis is a phenomenon in which a solvent flows between two solutions separated by a semipermeable membrane. This process is generally driven by concentration differences but can also result from electrical potential differences between two electrodes immersed in the solutions (electroosmosis) or temperature differences (thermo-osmosis).<\/p>
The less concentrated fluid flows toward the one with a higher concentration of dissolved solids until equilibrium is reached between the two solutions. This phenomenon is known as osmotic pressure.<\/p>
Reverse osmosis, used in water treatment, artificially reverses this process. It is a method of separating a solute from a solvent by applying external pressure to the membrane, reversing the osmotic flow. This causes the solvent to move from the more concentrated solution to the less concentrated one.<\/p>
In practice, water with a higher concentration of dissolved solids flows toward the less concentrated solution. The result is the separation into two distinct fluids: one highly concentrated, containing all the residues, and the other consisting of demineralized water.<\/p>
Reverse osmosis is the most refined water filtration technique and is used to remove a wide range of contaminants from water, including salts, pathogens, synthetic organic compounds, pesticides, and most other pollutants.<\/p>","protected":false},"excerpt":{"rendered":"
