There has been increasing interest in wastewater reclamation and reuse, as water supply reliability is continuously threatened. The reverse osmosis (RO) process is usually employed to produce high quality reclaimed water in the wastewater reclamation plant. However, the RO concentrate containing refractory organics becomes problematic in both cases of direct discharge and returning to the wastewater treatment plant. In this study, different oxidation technologies including the conventional Fenton process, UV/H2O2, ozonation, and electrochemical oxidation processes were tested for the treatment of organics in the RO concentrate from a wastewater reclamation plant. The removal of TOC and micropollutants in the RO concentrate was examined, and the treatment costs were compared for the different oxidation processes. |
