<p>An electrode membrane stack (16) for use in an electrodialyzer has two pairs of electrodes (5, 7 and 6, 8), of which only one pair is connected to a power source (17) at any time. Polarity reversal of the membrane stack (16) is achieved by disconnecting one pair of electrodes (5, 7) from and connecting the other pair (6, 8) to the power source (17). Using alternate electrode pairs (5, 7 and 6, 8) to reduce polarity simplifies electrodes production and increases the operating life of the electrodes.</p> |
