Reverse Osmosis Plants
Reverse osmosis is a natural process which consists in the passage of water through a semi-permeable membrane from a diluted saline solution to another with greater concentration to create a chemical potential equilibrium. The pressure pushing the water through the membrane is called osmotic pressure.
By applying a pressure in excess of the osmotic pressure to the solution at higher salt concentration, the process is reversed: the water molecules pass through the membrane, while the molecules of salts, the organic molecules and almost the whole microbial charge are rejected. A concentrated solution is thus obtained on one side and pure water on the other one. This process is called reverse osmosis.
The plants designed and manufactured by Sireg Hydros make use, for demineralization/water desalination, of the reverse osmosis process, which, by exploiting the characteristics of special semi-permeable membranes and without the addition of any chemicals, totally remove from water both the organic pollutants (bacteria, viruses etc.) and the inorganic ones
(herbicides, pesticides, etc.) together with all of the salts in solution.
