Abstract

The objective of this investigation was to optimize and evaluate the bioenergy production potential and COD removal efficiency of a semi-continuous anaerobic digester from slaughterhouse wastewater. The performance of the pilot scale anaerobic digester was evaluated at the OLRs of 0.32, 0.51, 1.16 and 2.31 kg m⁻³day⁻¹ under mesophilic environmental condition (29.6±1.40°C). The COD removal eﬃciencies and methane yield in the pilot scale digester were in the range of 43.39 to 84.54% and 0.09±0.03 to 0.22±0.02 m³/kg COD removed, respectively with the maximum volumetric methane production (0.93±0.17m³/day) was achieved at the OLR of1.16 kg m⁻³ d⁻¹ corresponding to an optimum methane yield of 0.20 m³ CH₄ per kg COD removed. Generally, the results of this study showed that anaerobic digester is eﬃcient on generating bioenergy while treating high strength wastewater such as slaughterhouse wastewater. Hence, a full scale anaerobic digester should be developed and used to treat the wastewater generated in the slaughterhouse industries in Ethiopia where almost all the slaughterhouses discharge their wastewater to the nearby streams without prior treatment.
