Abstract
Microcystis aeruginosa (blue-green algae) is of concern in relation to drinking water because of its ability to produce toxins and odors that can significantly impair water quality. The drinking water contaminated with toxic cyanobacteria could cause the death of the domestic and wild animals and the cases of human illness. To minimize the threat, the treatment of eun-ophicated water con taining algae (M. aeroginosa) was conducted via electrochemical oxidation process, with titanium based anode coated with RuOz in this study. The research showed that the electrochemical oxidation process was effective in inhibiting the growth of the algae such as M. aerugznosa. The electrolysis parameters such as v electrolysis time, current density, and electrodes distance were analyzed by the orthogonal collocation method. The results showed the electrolysis time was the dominant factor for the inhibition of the algal growth. The optimal operating conditions werev current density of 10 mA/cm2 and the electrodes distance of 6 cm. The inhibitive efficiency was 92. 64% with the electrolysis time of 40 minutes. The preliminary mechanism of this process was also explored and proposed in this paper.
