The current density with which the process is used is of essential importance for the economy of a method of electrolytically treating materials. Normally only low or medium current densities are used, as the speed of replacement of consumed materials in the direct vicinity of the surface of the material for treatment has a restrictive effect on the magnitude of the current density at which a usable process result can still be achieved. However, a low current density leads to long electrolysis times and to complex treatment installations.The opportunity afforded according to the invention of improving the transfer of materials at the surface of the material for treatment consists in generating a large flow of electrolyte at the treatment point by means of rotating electrodes which are movable synchronously with the surfaces of the material for treatment, and which may be electrically polarized with respect to the material for treatment, out of which the treatment agent emerges through openings, or into which it is sucked through openings.
