CO-TREATMENT OF LEACHATE AND DOMESTIC SEWAGE AND ITS INFLUENCE ON NITROGEN REMOVAL

Abstract This research investigated the performance of two pilot-scale treatment plants: an activated sludge and a hybrid model type IFAS (Integrated Fixed-Film Activated Sludge), combining sanitary landfill leachate with domestic sewage treatment with the objective of removing organic substances. In order to assess the possible impacts on the treatment, three experimental phases were developed with leachate inputs in the influent composition: 5%, 10% and 20% of the total load of BOD. As can be seen from the results, even with the highest levels of leachate input, there were no significant cha...
