(oz-mō′sĭs) [Gr. osmos, impulse, + osis, condition]
Enlarge picture
The passage of solvent through a semipermeable membrane that separates solutions of different concentrations. The solvent, usually water, passes through the membrane from the region of lower concentration of solute to that of a higher concentration of solute, thus tending to equalize the concentrations of the two solutions. The rate of osmosis is dependent primarily upon the difference in osmotic pressures of the solutions on the two sides of a membrane, the permeability of the membrane, and the electric potential across the membrane and the charge upon the walls of the pores in it.

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.

Osmotic dehydration is widely used as pre-treatment to the other process, such as hot air drying, freezing, lyophilization among others, and this treatment also has the advantage of a good conservation of sensory attributes such as color, flavor and texture.
