Systems and methods are described that combine capacitive deionization (CDI), electrodeionization (EDI) mechanisms and use of Radio Waves for deionizing aqueous or nonaqueous solutions. The inventive systems and methods modify certain known Capacitive Deionization using coatings or films by applying low frequency radio wave signals at low power and using wire mesh spacers that separate the ionic charges on the electrodes. Benefits derived from these improvements include: (a) maintaining a lower level of purification； (b) increasing by as much as 25% the rate of expulsion of ions during regeneration； (c) increasing by as much as 50% the rate of electrical discharge of the cell； (d) decreasing the regeneration time (producing as much as 33% more purified water per unit of time)； (e) reducing by as much as 25% the power required； (f) improving the recovery of the system to as much as 85% and (g) a 4 log kill of microbes and filtration of microbes.
