The full form of RO is Reverse Osmosis. Reverse osmosis is a specific filtering method that uses a semipermeable, porous membrane to remove pollutants and big molecules from the water by allowing only pure water to pass through it.
Production of drinkable water in water treatment facilities and manufacturers is where RO technology is most commonly used. The solute is the end product. It happens when the membrane’s pure solvent is allowed to follow one end of the membrane, allowing a solvent to build up on the membrane’s suitable side. Reverse osmosis eliminates bacteria and other dissolved and suspended organisms from water.

Working Principle of Reverse Osmosis
The osmosis concept is reversed in reverse osmosis. Pressure is applied to the salt solution as it is pushed up against the semipermeable membrane. In this instance, the applied pressure exceeds the osmotic pressure. The molecules are thereby transitioning from a highly concentrated solution to a less concentrated solution.

It is the process by which solvent molecules move from a location of lower concentration to one of higher concentration through a semipermeable membrane. | This is how molecules of a solvent move from a region of high concentration to one of low concentration when a force greater than the osmotic pressure is applied. |
It takes place alongside a possible gradient. | Against the potential gradient, it occurs. |
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. |
