Removal of algae by electrochemical treatments through electrochemical generation of persulfate and hydrogen peroxide was investigated in a fixed bed reactor. The cell was equipped with two electrodes (two identical graphite anode and cathode). The effect of different operative parameters, such as applied potential and amount of initial sodium sulfate added in the case of persulfate production was evaluated. In addition, the influences of potential differences in the case of hydrogen peroxide production were addressed. The two treatments were optimized, and their high efficacy in removing algae-laden water was proved upon application to collected samples obtained from the reservoir of Rod El-Farag drinking water station. The pro-type system used with the proposed methods is simple, fast, and effective to remove algae from water sources.
