dc.description.abstractIn this paper, the application of combined S2O82- / Zn2+ oxidation was investigated for landfill leachate treatment. Several dosage ratios (g/g) from Sodium persulfate (Na2S2O8 M = 238 g/mol) and Zinc chloride (ZnCl4 207.1920 g/mole) were added to the leachate sample in one oxidation reactor. Results showed that the maximum removal efficiencies for COD (88%) and colour (98%) were obtained using 2 g/12 g S2O82- / Zn2+ dosage, pH (11), and 120 min reaction time, while the maximum removal for NH3-N (60%) was obtained at 180 min of oxidation. In addition, the biodegradability (BOD5/COD) ratio was improved from 0.07 to 0.19. Moreover, the performance of the new oxidation processes (S2O82- / Zn2+) compared to other related treatment processes such as S2O82- oxidation alone, ZnCl4 coagulation, S2O82- oxidation followed by ZnCl4 coagulation and ZnCl4 coagulation followed by S2O82-. The results of S2O82- / Zn2+ oxidation achieved higher removal for COD, colour and ammonia compared to other related processes. The results revealed that S2O82- / Zn2+ oxidation system can be recommended as an efficient process for organic and ammonia removal from leachate.en_US
