WebJul 3, 2024 · Reverse osmosis or RO is a filtration method that is used to remove ions and molecules from a solution by applying pressure to the solution on one side of a semipermeable or selective membrane. Large molecules (solute) can't cross the membrane, so they remain on one side. Water (solvent) can cross the membrane. WebForward osmosis (FO) is a water separation process which uses a semipermeable membrane and the natural energy of osmotic pressure to separate water from dissolved …
