About reverse Osmosis process
The reverse osmosis process is used in case of
water high salinity (from 500 to 50.000 ppm) and allows to obtain efficiencies
of 95% in solved solid removal and 100% in bacteria and virus removal.
The term osmosis means, in physics and chemistry, a phenomena consisting
in the movement of diffusion of two miscible liquids of different concentration,
through a porous septum or a membrane, semi-permeable or permeable, to both
Each solution has an osmotic pressure directly proportioned to its molality.
When on the two sides of the membrane we find solutions of different
concentration, the difference of osmotic pressure moves the solvent molecules of
the most diluted solution towards the most concentrated one, till the
concentration of both solutions become identical.
Reverse osmosis is, the phenomena that happens when on the surface of a
semi-permeable membrane dividing two solutions of different concentration, is
applied a difference of pressure contrary and superior to the osmotic pressure,
so that the flow of solvent comes up from the most concentrated solution to the
