Advanced Treatment of Landfill Leachate: Advanced Oxidation Combined with a Membrane Bio-reactor for Landfill Leachate Treatment. Sumitha Sumanaweera

Treatment of landfill leachate is a challenge specially to the developing countries in the process of protecting their environment due to unaffordability of the available technologies. This study, Advanced oxidation combined with Membrane Bio- reactor (MBR) is an effort to achieve better treatment technique. It focuses on reduced need for infrastructure and smaller foot print of treatment facility by using MBR technology to perform activated sludge process. The subsequent advanced oxidation by ozone facilitates further treatment. Leachate of average age was preteated and fed into a laboratory MBR treatment module. Pretreatment efficiency and the change of MBR efficiency by recirculating the ozonated effluent were studied.
