ABSTRACT:
Electrolysis of impure solutions containing hardness impurities such as calcium and magnesium causes deposits to form on the cathodes of such an electrolysis cell which rapidly reduces the efficiency of the cell. The electrolysis cell of the instant invention contains a plurality of cathodes. The efficiency of such a cell is rejuvenated periodically by changing the polarity of less than the total number of cathodes in said cell so as to clean such cathodes while continuing normal operation of the cell by means of the remaining cathodes.
