This paper presents several results of treatment of organic compounds from landfill leachate from Kieu Ki landfill site in Viet Nam by using ozonation processes to determine some suitable conditions in Vietnam. Before treating by Ozone, landfill leachate was pre-treated by coagulation. pH range between 5 and 10, reaction time between 20 and 120 min were selected by ozonation process in this research. As the result, the optimums was achieved at pH of 8 and reaction time of 80 min, COD was removed from 2,109 mg l-1 to 1,043 mg l-1 and color between 2,012 and 333 Pt-Co in this study.
