First Claim
Patent Images
1. A method for cleaning an electrolytic cell comprising electrodes, the method comprising the steps of:
- reversing polarities of two or more of the electrodes; and
providing a cleaning current density to the electrodes which is lower than an operational current density used during normal operation of the electrolytic cell.

Abstract
Method and apparatus for a low maintenance, high reliability on-site electrolytic generator incorporating automatic cell monitoring for contaminant film buildup, as well as automatically removing or cleaning the contaminant film. This method and apparatus preferably does not require human intervention to clean. For high current density cells, cleaning is preferably performed by reversing the polarity of the electrodes and applying a lower current density to the electrodes. A second lower current density power supply may be used for reverse polarity cleaning. Electrolyte flow is preferably monitored and automatically adjusted.
