reverse osmosis method

Reverse osmosis Wikipedia

Reverse osmosis (RO) is a water purification process that uses a partially permeable membrane to remove ions, unwanted molecules and larger particles from drinking water. In reverse osmosis, an applied pressure is used to overcome osmotic pressure, a colligative property, that is driven by chemical potential differences of the solvent, a thermodynamic parameter.

What Reverse Osmosis Is and How It Works ThoughtCo

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.
