Build-up Phenomenon and Self-Cleaning Effect upon Wire Electrode Surface of an Electrolytic Ozone Generator in Tap Water

수 분해형 오존발생장치의 전극선 비대현상과 자기회복 현상

The negative wire of an electrolytic ozone generator, proposed by authors, has been contaminated by attaching the impurity particulate in tap water, which is called BUILD-UP phenomenon. The higher applied voltage and the larger wire diameter have shown the higher build-up rate, which makes the current reducing largely and concurrently the ozone production smaller. It is found that the positive electrode of the ozone generator has a strong SELF-CLEANING effect by detaching the impurity particulate from its surface, which, however, is used us a novel means of solving the build-up problem. As a result, the build-up problem can be solved effectively by applying an alternate square wave pulse voltage to the electrodes so as to get the self-cleaning ability on the both electrodes during each of the half pulse duration time.
