Electrolytic cell for treatment of water
First Claim
1. An electrolytic cell for the treatment of water, which comprises a closed container with a lower inlet opening and an upper outlet opening for the water, at least two radially positioned electrodes which are adapted to be connected with the positive and with the negative pole of a DC source, particles located in the interior space of the electrolytic cell whose density is higher than that of water and gratings arranged in back of the lower water inlet opening and in front of the upper water outlet opening, said gratings having openings smaller than the diameter of the particles in the interior of the electrolytic cell, to prevent the particles from emerging from the electrolytic cell.

Abstract
The specification describes an electrolytic cell for the treatment of water, comprising a closed container with a lower inlet opening and an upper outlet opening for the water and a cathode and an anode. In the interior of the electrolytic cell particles are located whose density is higher than that of water and which are prevented from leaving the electrolytic cell by gratings adjacent to the inlet and the outlet.

21. An electrolytic cell for the partial or complete removal of temporary hardness (line hardness) from water, comprising a closed container with a lower inlet opening and an upper outlet opening for the water and at least two radial electrodes consisting of copper, iron or aluminum which are adapted to be connected with the positive and with the negative pole of a DC source, a tubular platinum or tantalum electrode arranged in the center of the cell, a porous member and a grid tube surrounding said centrally positioned electrode, said grid tube defining an anode compartment having at both ends a respective opening with an adjustable diameter, the outflow from the water passing between the radial electrodes and the outflow from the anode compartment being removed separately.

22. An electrolytic cell for the disinfection of chloride-containing or chloride-free water by the formation of chlorine or per-compounds comprising a closed container with a lower inlet opening and an upper outlet opening for the water and at least two radial electrodes consisting of aluminum, iron, copper, platinum or tantalum which are adapted to be connected with the positive and with the negative pole of a DC source, a positive platinum or tantalum electrode arranged in the center, a porous membrane and a grid tube surrounding said central electrode, said grid tube defining an anode compartment and having at the top an opening with an adjustable size.
