Classification: CPC C  B | IPC C

Claim 24:
25. A non-transitory, computer-readable medium storing instructions which, when executed by a processor of a water purification apparatus, cause the processor to:
obtain, via a sensor, a current or voltage value indicative of power consumption by an electrically controlled deionization unit;
determine whether the obtained current or voltage value meets at least one power consumption criterion; and
control, using one or more valve units, recirculation of reject water produced by the water purification apparatus based on the determination, including increasing the recirculation of reject water in response to a determination that the obtained current or voltage value indicative of power consumption is below a first threshold or decreasing the recirculation of reject water in response to a determination that the obtained current or voltage value indicative of power consumption is above a second threshold.
