Abstract
An apparatus to remove ions, the apparatus including an inlet to let water in the apparatus; an outlet to let water out of the apparatus; a capacitor; and a spacer to separate a first and a second electrode of the capacitor and to allow water to flow in between the electrodes. The apparatus further including a power converter configured to convert a supply voltage of a power source to a charging voltage to charge the capacitor. The power converter is constructed and arranged to recover energy from the capacitor by converting the voltage on the capacitor to supply voltage of the power source.
