UV-Hydrogen Peroxide (UVHP) system is one of the alternative methods for the treatment of landfill leachate. This study focuses on the effectiveness of UVHP system for the treatment of Pulau Burung Landfill Site (PBLS) leachate by examining the effect of operating parameters to the treatment efficiency. Experimental design for UV-Hydrogen Peroxide treatment involves Three- Level Factorial design and the data is analysed using the Response Surface Methodology (RSM). The factors for the experiments are pH, reaction time and hydrogen peroxide concentration while the responses are removal of chemical oxygen demand (COD) and colour of the sample. Another response for this treatment is 5-day biological oxygen demand (BOD5) purposely to check the biodegradability of the leachate by BOD/COD ratio. The trend of colour removal and COD removal with respect to pH, reaction time and hydrogen peroxide concentration is to be been determined. From the results, it is shown that low level pH, high level hydrogen peroxide concentration and high level reaction time gives greater removal of colour and COD. Treatment at pH 2, hydrogen peroxide concentration of 5000 mg/L and reaction time at 90 minutes achieves maximum colour, 87.82%. Whereas, the maximum COD removal also occurs at the same treatment conditions which is 50.66%. The BOD of leachate also has been improved to comply with the Environment Quality Act (EQA) Standard after UVHP treatment. The maximum removal of BOD is 80.3%, reduced from 317 mg/L to 62.44 mg/L. UVHP treatment is an effective alternatives method for removal of colour, COD and BOD of PBLS leachate. iii
