CONTROLLER AND METHOD OF OPERATION OF A CAPCITIVE DEIONIZATION SYSTEM

摘要

Embodiments of the invention provide a method of operating a flow- through capacitor and a related controller for performing the method. The method includes establishing a summed-current capacity of the flow-through capacitor. In an operational cycle, the flow-through capacitor is operated to transfer ions between the pair of electrodes and water. A current is monitored during operation of the flow- through capacitor. This current is integrated over time to calculate a monitored-current value. To determine an end of the operational cycle, the monitored-current value is compared to the summed-current capacity.
