Osmosis is the natural principle that when two different salt concentration solutions are separated by a semipermeable membrane, the water passes from the less concentrated solution to the more concentrated. If external pressure is applied to the more concentrated solution, the process is inverted, giving rise to the phenomenon of reverse osmosis (the water passes from the more concentrated solution to the less concentrated one).

The reverse osmosis technology, thanks to its scalability, proves to be efficient and convenient both when applied to meet relatively small and discontinuous needs, in the order of 500-1000 liters per day typical of small pleasure boating, and for continuous cycle treatment of quantities that guarantee the needs of entire communities, cruise ships, entire industries: hundreds of cubic meters per day.

THE OSMOTIC MEMBRANE
The application of this process is modular: from the smallest single membrane desalinators to treatment systems made up of thousands of elements (in series or parallel), efficiency is increasing, thanks also to the continuous development of new materials and membranes increasingly sophisticated.
