I came up with a simple electric water filter idea.
Its basically two sections of activated carbon pressed in stainless steel tubes which the water pass thru but theres a spacing between the two forming a gap such to have a valve installed for discharging some of the water during the cycles.
During the charging cycle the water is forced from tank A (initial water) to tank B (deionized water) and the water is recirculated between the two tanks passing thru the filter while some voltage is applied to the carbon sections. When the carbon is full of ions a mechanic valve opens and let some water to leak out, flushing out the dirty while the capacitance is discharged. The capacitance can be charged reversely than to help complete discharge of the ions from the carbon sections.
It can be arranged in such way that gravity works helping some of the tank B water leak back cleaning the lower portion of active carbon.
A polymeric filter can be used in combination.
Yes with the water being constantly purified its easier to get to apply higher voltage to it.
As the carbon has a gigantic active area the capacitance become giant and thus many charges get trapped by the filtering. Getting charges busy seem a good way to allow high voltage application.
If you feel thankful and want to repay please let me know.
