installation for the desalination of sea water by reverse osmosis, pressure and method for desalination of sea water by reverse osmosis, pressure clean

摘要

The invention relates to a plant for desalting marine water by reverse osmosis. The desalting plant comprises a salted water tapping point (1), salted water transporting means (2), salted water column forming means (3), reverse osmosis desalting means (4) which are situated in the area of the lower end (3b) of the salted water column (3) and which may be situated above or under the sea surface, the salted water transporting means (5) and brine conveying means (6). The means (3) which form the salted water column have a height such that its weight exerts a pressure which contributes substantially to generate the reverse osmosis phenomenon, so that the salted water is separated into desalted water and brine. The plant includes at least one salted water head tank (7) located at a predetermined height at the upper zone (3a) of the water column (3), said head tank (7) being in fluid communication with said water column. The invention also relates to the corresponding process. IMAGE
