Process of Osmosis

The process of osmosis is the process in which is forced the passage of solvent molecules from the more concentrated solution to the less concentrated, and is obtained by applying to the more solution a greater pressure than the osmotic pressure.
Reverse osmosis is made with a membrane that retains the solute preventing the passage and allowing to the derive the pure solvent.
The process of osmosis is a system of depuration of the waters that exploits the physical capacities of semipermeable membranes.
By applying correct pressure to the water to be treated, we can obtain water purified of salts and other micro pollutants such as pesticides, virus and bacteria with a molecular value of over 100.
The process does not imply the use of chemical reactants.
The principle advantages are: the possibility of meeting the needs in the event of lack of drinking water or to momentary request of drinking water superior to the availability.
Examples of applications are the purification of salty or marine waters into drinking water for consumers as well as for community water treatment.
