%X the aim of this article was evaluate the implementation of the ammonia stripping as a pretreatment for landfill leachate and the use of the coagulation-flocculation-sedimentation process for the removal of refractory organic compounds present in a landfill leachate pretreated in an activated sludge system. the rates of ammonia nitrogen removal ranged between 3.5 and 3.6 mg nh3-n.l-1.h-1in a lab scale reactor (working volume of 20 l) equipped with a mechanical stirrer and 3.2 and 3.3 mg nh3-n.l-1.h-1in a lab scale aerated column (working volume of 10 l). it was possible to achieve removals above 90% of refractory organic compounds (measured as apparent color) applied coagulant dosage about 400 mg fe+3.l-1 and 400 mg al+3.l-1.
