Zusammenfassung:The present disclosure relates to a capacitive deionization (CDI) device.In an aspect, a CDI device (40) is provided comprising at least one inlet (47) where aqueous media enters the CDI device (40), a plurality of CDI cells (41a, 41b, 41c) configured to subject the aqueous media to capacitive deionization, each CDI cell being arranged with a first electrode (43a, 43b, 43c) and a second electrode (44a, 44b, 44c) arranged to be energized with opposite charges via a respective conductor (45a, 45b, 45c, 46a, 46b, 46c) in order to subject the aqueous media flowing through the CDI cell to capacitive deionization, and at least one outlet (48) where the aqueous media having been subjected to capacitive deionization by the CDI cells (41a, 41b, 41c) exits the CDI device (40). The CDI device (40) further comprises a processing unit (42) to which the conductors (45a, 45b, 45c, 46a, 46b, 46c) are connected, the processing unit (42) being configured to individually control each of the electrodes for providing a required voltage (V+, V-) to energize the first electrode (43a, 43b, 43c) and the second electrode (44a, 44b, 44c) of each CDI cell (41a, 41b, 41c) with a desired charge and for controlling interconnection of the electrodes between the CDI cells (41a, 41b, 41c) to selectably configure the CDI cells (41a, 41b, 41c) in parallel or series configuration.
