The characteristics of landfill leachate were analyzed accordingto standard methods for the examination of water and wastewater[16]. pH was analyzed by using portable meters. Organic com-pounds were determined in term of biochemical oxygen demand(BOD5) using a 5-day BOD test, chemical oxygen demand (COD)using closed dichromate reflux method. Suspended solids (SS) weredetermined by gravimetric method. Ammonia nitrogen (NH3–N)and total Kjeldahl nitrogen (TKN) were analyzed by distillation andmacro-kjeldahl methods.
