Title (EN) METHOD AND PLANT FOR DESALTING SEAWATER EXPLOITING HYDROSTATIC PRESSURE
(FR) PROCEDE ET INSTALLATION DE DESSALAGE DE L'EAU DE MER DANS LESQUELS LA PRESSION HYDROSTATIQUE EST EXPLOITEE
Abstract: front page image
(EN) The invention relates to a method and a plant for seawater desalting which is to be located under seawater level and is capable of exploiting the hydrostatic pressure that builds up at an at least 250 metre depth on one side of a semipermeable filter membrane, in order to overcome the osmotic pressure which is characteristic of salt water itself, whereas the other side of the membrane is kept at atmospheric pressure, whilst pumping operations are only reduced to those related to the fresh water obtained from the filtration.
(FR) L'invention concerne un procédé et une installation de dessalage de l'eau de mer. Ladite installation doit être installée au-dessous du niveau de la mer et est capable d'exploiter la pression hydrostatique s'accumulant à une profondeur d'au moins 250 m, d'un côté d'une membrane de filtrage semi-perméable, de sorte que cette dernière résiste à la pression osmotique caractéristique de l'eau de mer, alors que l'autre côté de la membrane est maintenu à la pression atmosphérique, les opérations de pompage étant réduites à celles relatives à l'eau douce obtenue par la filtration.
