re·verse os·mo·sis

movement of solvent in the opposite direction from osmosis, that is, pressure filtration of solvent through a semipermeable membrane that will hold back the solutes; commonly replaced by filtration or ultrafiltration when speaking of capillary membranes, as in the renal glomerulus.

(rē-vĕrs' os-mō'sis)
Movement of solvent in the opposite direction from osmosis.

reverse osmosis

A form of water treatment that removes infectious particles and dissolved ions more effectively than other water purification techniques. Water so purified can be used in hemodialysis.
