<p>Simple covered lagoons are used to treat wastewater from commercial pig farms in Cambodia into biogas. The electricity is generated from biogas using a generator. However, high level of H2S corrodes or breaks down the generator. This study aims to desulfurize biogas with commercial ferrous oxide pellets (Fe2O3). The effects of desulfurization system on biogas production, electricity generation, and CO2 reduction are discussed. The results show that H2S was reduced from 2,000 ppm before treatment to around 50 ppm after treatment. CH4 (57.7 ± 8.76%) and CO2 (24.7 ± 2.67%) contents were not affected by desulfurization. O2 content was changed from 0.3 to 4.8%. High O2 level was a sign of pipe leakage, lowering CH4 and eventually electricity production. The increase of O2 level decreased CH4, thus lowering generator performance. Actual electrical output power produced from biogas was 368.5 ± 29.3 kW, with loading rates of 57.6 ± 4.6% and generator efficiency of 26.8 ± 1.7%. Estimated amounts of 22,818 tCO2equ were reduced by the biogas system. The desulfurization system was highly effective in H2S removal without affecting biogas quality. For the long-term biogas systems in Cambodia, local-made desulfurization systems should be tested and compared with imported products.</p>
