Electrochemical removal of Bisphenol A from landfill leachate under Nordic climate conditions
Abstract This study investigated the applicability of electrochemical oxidation for landfill leachate treatment in climate areas, where cold temperatures prevail (like Northern Norway). Experiments were completed with pre-treated (coagulation/flocculation and separation) landfill leachate at 6 and 2...
