Abstract
Management of municipal solid waste leachate has become an urgent environmental problem in many countries due to the high growth of population and consumption trends. Advanced oxidation processes (AOPs) are efficient methods to treat leachate because of their high ability to reduce unpleasant parameters. Although the simultaneous application of different AOPs methods is more effective than a single process, the simultaneous application of AOPs for the treatment of municipal solid waste leachate has received little attention. To fill this knowledge gap, this study presents the simultaneous application of AOPs methods to treat municipal solid waste leachate. The efficiency of AOPs was studied in terms of organic compounds such as chemical oxygen demand (COD) and total organic carbon (TOC). Leachate samples were collected from the Barka landfill, which is located in the northeast of Oman. Four combinations of applied AOPs methods (e.g. ozone (O3), hydrogen peroxide (H2O2), and ultraviolet (UV)) in this study resulted in the order of H2O2/O3/UV > H2O2/O3 > O3/UV3 > H2O2/UV according to the COD removal efficiency. Combining these AOPs methods resulted in about 1.5 times increase in COD removal (56.62%) and 1.9 times increase in TOC removal (39.34%) compared to the individual applications.
