BOD:COD Ratio as an Indicator for Pollutants Leaching from Landfill

Aik Heng Lee and Hamid Nikraz
Abstract—The relationship of BOD to COD of leachate from a mature landfill site are investigated over a period of six years to determine the indicator to be used for prediction of leachate characteristic generating from landfill site. Results of the investigation reveal that BOD:COD ratio is a good indicator of degradation of organic matter in landfill. It can be used as an indicator for degradation of organic matter that differentiate the acetogenic phase from methanogenic phase in this landfill

Index Terms—BOD:COD ratio, landfill leachate, waste decomposition.
