What Is the Full Form of RO?
The full form of RO is Reverse Osmosis. Reverse Osmosis is a particular filtration process which utilises a semipermeable, porous membrane which only enables clear water to move through it, removing the impurities and large molecules.
RO technology is primarily applicable to portable water production in water plants and factories. The final byproduct is the solute. It happens when the pure solvent is permitted to follow one end of the membrane, allowing the accumulation of a solvent on a suitable side of a membrane. Reverse Osmosis removes suspended microorganisms and kinds that have been dissolved from water, such as bacteria.
Working Principle of Reverse Osmosis
Reverse Osmosis operates by reversing the osmosis principle. The salt solution is pushed against the semipermeable membrane and put under pressure. Here, the pressure applied is greater than the osmotic pressure. So the molecules are going from a highly concentrated solution to a less concentrated solution.
Difference between Osmosis and Reverse Osmosis
| Osmosis | Reverse Osmosis |
| It is the mechanism by which the solvent molecules migrate through the semipermeable membrane from the lower concentration area to a higher concentration. | This is the method by which a solvent’s molecules pass via the semi-permeable from a region of high to low concentration when pushing higher than the osmotic pressure is applied. |
| It happens along with a potential gradient. | It happens against the potential gradient. |
| It is noticed during stomatal opening and the absorption of water from the soil by the roots. | It is observed in the water purification system. |
