Reverse Osmosis:When too much pressure is applied to the bulk solution (salt solution),the osmosis effect is reversed - the solvent (water) moves from the densest to the lightest solution. From the film, almost pure water (H2O) comes out, which we use. The partof the solution with high salt concentration (denser) is discharged into the drain. In this way, brackish or hard water is converted into drinking The water is processed before it enters the membrane so it does notdestroy it, as well as after it passes through the membrane to make it drinkable. Reverse Osmosis is called RO by Reversed Osmosis.#4. ATHANASIADIS
