ABSTRACT:
A method for removal of solid deposits from surfaces of electrodes of a DC electrolytic cell for disinfecting of water in a closed system, especially in a swimming pool, SPA or hot tub, includes simultaneous spinning the water over the electrode surfaces and electrolytic release of the deposits from the surfaces without interruption of the disinfecting process. The method further includes a) changing the polarity of the electrodes of the cell at predetermined frequency for electrochemically releasing the deposited scale from the electrode surfaces; b) circulating the water through a hydrocyclone containing a DC electrolytic cell for disinfecting of the water so that the deposits are washed off the electrodes of the cell; c) periodically removing the scale particles from a drained chamber located at the bottom of the hydrocyclone.
