An electrolyte line extends from the outlet of an electrolysis device to a collecting tank and from the same back to the inlet of the electrolysis device. The electrolyte is passed from the outlet of the electrolysis device to a first container which is disposed at a higher level than a second container. Electrolyte collected in the first container is periodically discharged through a first syphon line into the second container, and electrolyte collected in the second container is periodically discharged through a second syphon line into the collecting tank which is disposed at a lower level than the second container. The outlet end of each syphon line is disposed at a distance above the liquid level of the container disposed thereunder, so that electrolyte always flows only in one of the two syphon lines or in none of the syphon lines. When electrolyte flows in none of the two syphon lines, electrolyte is preferably supplied from the collecting tank into the second container. |
