Abstract:
A fluid deionizing apparatus comprising:a tank member containing therein a plurality of deionization cells arranged back-to-back, each deionization cell comprising:a non-sacrificial carbon-reinforced electrode of a first type formed from a first material; anda non-sacrificial electrode of a second type positioned on either side of said electrode of a first type, said electrode of a second type being formed from a second material different from said first material;a first power supply configured to provide a first voltage differential between the electrode of the first type and the electrodes of a second type in each of a first number of deionization cells;a second power supply configured to provide a second voltage differential between the electrode of the first type and the electrodes of the second type in each of a second number of deionization cells, wherein said first and second voltage differentials are different from one another.
