    2010-1-1 · Reverse osmosis (RO) is a membrane filtration process for removing solvent from a solution by leaving a concentrated solution behind. When a semipermeable membrane separates a dilute solution from a concentrated solution, the solvent crosses from the dilute to the concentrated side of the membrane in an attempt to equalize concentrations.
