Title (EN) PROCESS AND DEVICE FOR REMOVING VALUABLE MATERIALS DISSOLVED IN SEA WATER
(FR) PROCEDE ET DISPOSITIF POUR EXTRAIRE DES MATIERES DE VALEUR DISSOUTES DANS L"EAU DE MER
Abstract: front page image
(EN)The processes and devices known heretofore for removing valuable materials dissolved, particularly uranium oxide, in sea water passing through absorbing layers have not yet met any success in the implementing thereof, because of the suspension materials in water in areas close to the coastline and because of the high energy required for pumping sea water at high levels. To provide a practicable removal process with high efficiency and low energy consumption, it is proposed to arrange the absorbing layers into elements shaped like floating pontoons on sea and to pass sea water therethrough by means of pumps.
(FR)Les procedes et les dispositifs connus jusqu"a present pour extraire des matieres de valeur dissoutes, en particulier l"urane, de l"eau de mer par passage a travers des couches absorbantes n"ont pas encore eu de succes dans leur mise en oeuvre, a cause des matieres en suspension dans l"eau dans les regions proches du littoral et a cause de la grande energie necessaire pour le pompage de l"eau de mer a des hauts niveaux. Pour arriver a un procede d"extraction praticable a haut rendement et faible en besoin d"energie, l"invention propose de mettre les couches absorbantes dans des elements en forme de pontons flottants sur la mer et de faire passer l"eau de mer a travers au moyen de pompes.
