Abstract
Eutrophication proceeds in many lakes, marshes and ponds with an unusual growth of algae so that it became a serious problem in especially urban areas. Though many approaches were made to improve the eutrophicati on in the past, e.g., oxidation treatments represented by ultraviolet radiation and ozonation showed rather high effect to reduce algae. Also, an electric disinfection treatment represented by use of electrolysis to produce strongly acidic water is attracting more attention than before, because of strongly acidic and to produce a free chlorine.<br>The authors performed an experimental study focusing on the electrolytic oxidation treatment of algae in lake and marsh water, to examine its effect on the disinfection of algae using a batch- and circulation-type apparatus of laboratory scale.<br>As for the electrolytic oxidation treatment, it showed a great effect on the disinfection of algae. It was found also that there was a correlation between the effect and the quantity of electricity. It was found, further more, that a free chlorine produced by the electrolytic oxidation enhanced the disinfection of algae. On a continuous electrolytic oxidation treatment, the electrolytic cell used for the experiment made more than 24s · A in contact reaction time necessary.
