Assessing membrane performance for landfill leachate treatment in accordance with local regulatory requirements

Poor landfill management is always associated with environmental problems such as the discharge of leachate that does not comply with environmental regulations. In this work, we carried out a comprehensive assessment of the quality of leachate treated by four different types of commercial polymeric...
