Title
(EN) DESALINATION DEVICE AND METHOD OF MANUFACTURING SUCH A DEVICE
(FR) DISPOSITIF DE DÉSALINISATION ET PROCÉDÉ DE FABRICATION ASSOCIÉ
Abstract
(EN)
A device (10) for capacitive deionization of an aqueous media containing dissolved ion species, said device comprising a cell with a first primary electrode (2) and a second primary electrode (3) arranged opposite the first primary electrode (2) and preferably separated by at least one non-conductive spacer (4, 4'). A third electrode (7) is arranged between the first and the second electrode. The third electrode (7) is grounded whereas the first and the second electrodes are polarized versus the grounded third electrode.
(FR)
La présente invention concerne un dispositif (10) de désionisation capacitive d'un milieu aqueux contenant des espèces ioniques dissoutes, ledit dispositif comprenant une cellule avec une première électrode primaire (2) et une deuxième électrode primaire (3) disposée à l'opposé de la première électrode primaire (2) et de préférence séparée par au moins un espaceur non conducteur (4 4'). Une troisième électrode (7) est disposée entre la première et la deuxième électrode. La troisième électrode (7) est mise à la terre tandis que les première et deuxième électrodes sont polarisées par rapport à la troisième électrode mise à la terre.
