| Research Abstract |
The conventional advanced oxidation processes (AOPs) have defects of high costs of special apparatus and/or heavy chemicals management. Accordingly, new AOPs, namely the electrochemical Fenton-type process (E-Fenton) and the electrolytic hypochlorous acid-hydrogen peroxide process (E-HOCl/H2O2), were developed in this research, in which chloride ion in wastewater was catalytically reused.
Effects of several operational parameters like current density and linear velocity on the performance of E-Fenton were evaluated, and the reusability of iron sludge was discussed. Consequently, E-Fenton was established as a new AOP requiring lower chemicals cost than the conventional one.
The availability of seawater as a chloride ion source for E-HOCl/H2O2 was demonstrated, and finally this process was proved to function well as a new AOP under neutral pH without sludge production.
