Abstract
A capacitive deionization device comprises: a pair of electrodes; and a controller configured to perform a water softening operation that applies a positive voltage across the pair of electrodes, configured to operate in a power-off mode that short-circuits or open-circuits the pair of electrodes based on termination of the water softening operation, and configured to perform a regeneration operation that applies a negative voltage across the pair of electrodes based on satisfaction of a predetermined condition while operating in the power-off mode.

A capacitive deionization device comprising:
- a pair of electrodes;
- and
- a controller configured to:
- perform a water softening operation that applies a positive voltage across the pair of electrodes,
- operate in a power-off mode that short-circuits or open-circuits the pair of electrodes based on termination of the water softening operation, and
- perform a regeneration operation that applies a negative voltage across the pair of electrodes based on satisfaction of a predetermined condition while operating in the power-off mode,
- wherein a product of an operating time of the regeneration operation and a magnitude of the negative voltage is less than a product of an operating time of the water softening operation and a magnitude of the positive voltage.
