| description | ABSTRACT In this work the leachate treatment of an urban landfill was carried out through a combination of coagulation/flocculation and adsorption processes. The leachate employed was collected in the municipal solid waste landfill of Muribeca-PE and coagulated with lime. The objective was to evaluate the use of oyster powder as adsorbent. The adsorption experiments were performed in batch using the best conditions for activation and process through two experimental designs. Then, the kinetic and equilibrium studies were carried out as well as an evaluation of each stage of the process. The equilibrium time was 40 min. Adsorption isotherms followed the Langmuir model and the maximum adsorption capacity was 45.45 Hazen.L.g-1. The combination of the treatment processes in question was very efficient, achieving a reduction of approximately 95% DBO, 40% COD, 70% of the leachate color. |
