Claim Text:
1. Operating method of an apparatus for purifying a fluid provided with an even number of cells, each of which: comprises at least one lead through condenser provided with two or more overlapping electrodes, facing one another, between which a flow of fluid to be treated containing ionized particles is susceptible to pass, and is electrically connected to a direct current power supply adapted to charge said electrodes at different polarities; said method cyclically comprising for each said cell: at least one charging step, in which said power supply charges the electrodes of said cell at different polarities; at least one service step, in which a flow of said fluid to be treated is forced to pass through the electrodes of the lead through condenser of said cell with progressive build-up of said ionized particles on said electrodes; at least one regeneration step, in which said electrodes are discharged and a flow of washing fluid is forced to pass in said condenser of said cell with consequent removal of said ionized particles built up on said electrodes; starting from the step of charging at least a first cell of said cells, electrically connecting in series a second cell of said cells, once its service step is completed and at the beginning of its regeneration step, with reverse polarity to said first cell to at least partially discharge its own electrodes on said first cell, in an energy recovery step.
