Reverse Osmosis is the smallest filtration by physical barrier today known. This process allows the removal from water of salts and other impurities. Driving farce of the process is the hydraulic pressure generated by pump that push the water through the membrane. The membrane allows to the cleaned fluid going through while keeps the pollutants.

While Demineralizer equipment are designed in order to produce a water quality with extremely low conductivity values, with Reverse Osmosis it is possible to achieve a water with low conductivity values, with no need of additional chemical process for the regeneration of the filtering element, since membring are self-cleaning.
