WebReverse osmosis pushes the solvent from its default position in a region of high concentration to the low solute concentration region with excess osmotic pressure. Forward osmosis is used to separate water out of solutions with other solutes in it. WebThis technique of reverse osmosis is used for large-scale desalination of seawater and on smaller scales to produce high-purity tap water for drinking. Figure 3.12. Applying a pressure greater than the osmotic pressure of a solution will reverse osmosis. Solvent molecules from the solution are pushed into the pure solvent.
