In particular high levels of BOD5 and COD in the waste water effluent pose significant risk on aquatic life through the depletion of dissolved oxygen, therefore treating the effluent to the acceptable permissible limits is essential for the health of the ecosystems. The study involved assessing the use of wood chips activated carbon in the treatment of the waste water effluent from the Doko waste stabilization pond and the research involved characterization of the waste water effluent in both the wet and dry seasons and the mean values of BOD5 and COD in the effluent for the dry season were found to be 172.3mg/l and 269.7mg/l and 129.1mg/l and 217.8mg/l for the wet season and these were higher than the recommended NEMA standards of 50mg/l for BOD5 and 100mg/l for COD, the study also evaluated the effectiveness of activated carbon in waste water effluent treatment where its adsorption behavior was described by the Langmuir and Freundlich models and the Freundlich model was the best fit for the adsorption of BOD5 and COD by activated carbon. The adsorption process demonstrated maximum percentage reductions of 75.6% for BOD5 and 72.4% for COD in the dry season and 80.3% for COD, 82% for BOD5 for the wet season bringing the BOD5 and COD values to the NEMA acceptable discharge standards demonstrating the potential of wood chips activated carbon in waste water effluent treatment.enThesis
