<P> Reverse osmosis ( RO ) is a water purification technology that uses a semipermeable membrane to remove ions , 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 . Reverse osmosis can remove many types of dissolved and suspended species from water , including bacteria , and is used in both industrial processes and the production of potable water . The result is that the solute is retained on the pressurized side of the membrane and the pure solvent is allowed to pass to the other side . To be `` selective '' , this membrane should not allow large molecules or ions through the pores ( holes ) , but should allow smaller components of the solution ( such as solvent molecules ) to pass freely . </P>
