mechanical cleaning of electrodes had been used to face the problem of deposition on cathode and anode plates, since this method has proved to be a better process for prevention of passivation in continuous systems. The stage of mechanical cleaning during the experiments can be seen in Fig. 2. The action of cleaning was performed manually after the end of each treatment run. According to Peter’s report (8), the most efficient and reliable method of electrode maintenance was to periodically mechanical cleaning of the electrodes which for large-scale, continuous
processes is a nontrivial issue.
