    Abstract

    Batu Gajah landfill site with the age of 40 years produced stabilized leachate which is highly contaminated and non-biodegradable. Batu Gajah leachate did not fulfil the discharge standard of Environmental Quality Regulations. Hence, treatment must be done before final discharged. Thus, this is study to measure characteristic of Batu Gajah leachate. Furthermore, it was also to investigate the effectiveness of ultrasonication on leachate as well as ultrasonication and hydrogen peroxide on the toxic leachate. It was found that through ultrasonication process, 50% amplitude is the optimum condition for ammoniacal nitrogen and 20% is the optimum condition for both suspended solid and BOD5. Higher reaction time could increase removal efficiency for all 3 parameters. Besides, the leachate contained foreign object that interfere the COD testing procedure, hence, the foreign object should be determined and removed before proceeding for COD testing. High pH was able to remove ammoniacal nitrogen and suspended solid effectively. Low pH was able to remove BOD effectively. Ultrasonication did improve the removal efficiency for all pH value. H2O2 was found to be improving the efficiency of removing the three parameters and ammoniacal nitrogen was absent after the ultrasonication and 0.5 g/L of hydrogen peroxide addition process. With addition of H2O2 , COD was not able to be tested well as H2O2 is also an interfering agent for COD testing.
