Abstract:
1. A method of operating a flow-through capacitor having at least a pair of electrodes spaced from one another to accommodate a flow of water and configured to transfer ions between the pair of electrodes and the water, the method comprising: establishing a summed-current capacity of the flow-through capacitor; operating the flow-through capacitor to transfer ions between the pair of electrodes and water in an operational cycle by controlling a current during operation of the flow-through capacitor wherein the current is maintained to be constant over at least some portion of the operational cycle; monitoring the current during operation of the flow-through capacitor and integrating the current over time to calculate a monitored-current value; and comparing the monitored-current value to the summed-current capacity to determine an end of the operational cycle.
