Application of external pressure to the salt solution side equal to osmotic pressure will also cause equilibrium. Additional pressure will raise the chemical potential of water in the salt solution
and cause a solvent flow to pure water side, now at a lower chemical potential. This phenomenon is called Reverse Osmosis.
Fundamentals
Reverse osmosis is a membrane separation unit. It is the forced passage of water through a membrane against the natural osmotic pressure to accomplish separation of water and ions.
Osmosis
Osmosis is a process which can be defined as a passage of liquid from weak solution to a more concentrated solution across a semi permeable membrane.

Separate the pure water from the solution containing solute with a semi permeable membrane that can only pass through water. At this time, the water on the pure water side will spontaneously pass through the semi permeable membrane and enter the solution side. The water surface ...
