<p>The disclosed device for the production of soft water from sea water, intended to be immersed into the marine medium, comprises a high pressure chamber (1) containing a semi-pervious selective reverse osmosis membrane (11) and a bell (14) provided with an axial internal piston (17) making it possible to obtain inside the chamber (1), by a multiplication effect, a pressure equal to the outside pressure multiplied by a ratio (S/s) of the useful surfaces of the bell and of the internal piston. The semi-pervious membrane communicates through a partition wall (3) of the high pressure chamber with the internal volume of the bell (15). Said internal volume communicates with the surface through a flexible tube (25) so as to act both as a gaseous atmosphere chamber on the one hand and as soft water collecting means after osmosis through the membrane, on the other hand.</p> |
