Operating method of an apparatus for purifying a fluid by means of an apparatus provided with an even number of cells, each of which comprises at least one lead through condenser and is electrically connected to a direct current power supply. The method foresees cyclically repeating, for each cell, a charging step, in which the power supply charges the electrodes of the cell at different polarity; a service step, in which a flow of fluid to be treated is forced to pass through the electrodes of the lead through condenser of the cell with progressive build-up of the ionized particles of the fluid on the electrodes; and a regeneration step, in which the electrodes are discharged and a flow of washing fluid is forced to pass in the condenser of the cell with consequent removal of the ionized particles built up on the electrodes. Starting from the charging step of at least one first cell of the two cells, the second cell, once its service step is complete and at the start of its regeneration step, is connected in series with reverse polarity to the first cell to at least partially discharge its electrodes on the first cell in an energy recovery step. During the energy recovery step the first cell is also jointly powered by the power supply, which detects the voltage on the first cell and by means of a control card controls the supply voltage to make a preset operating voltage across the first cell. |
