The most common municipal solid waste (MSW) disposal method is sanitary landfill. The major disadvantage of this method is the production of highly contaminated leachate. Not only physicochemical but also biological methods are sufficient alone in order to remove organics from leachate to get high effluent quality. Integrated processes that use physicochemical and biological methods at the same time like membrane bioreactors (MBRs) have been mostly employed in landfill leachate treatment in last decade. In this study, the removal of organic material using aerobic/anoxic MBR system followed by a nanoffltration process was evaluated.
