Experimental evaluation on the effect of biochar addition with anaerobic digestion of the tannery wastewater to improve biogas production
The use of biochar as an additive material in various compositions to the anaerobic digestion of the tannery wastewater was investigated. Pyrolytic biochar made from Khat waste with different compositions was added to anaerobic batch digesters in laboratory-scale biogas experiments. Biogas digesters with volume of 500 ml were used to explore the effects of biochar on anaerobic digestion in the ratios of 5, 10, 15, and 20% (w/w) at constant mesophilic temperature (38 °C). The results show that for five experimental tests in digesters (D0, D1, D2, D3, and D4), which contains 0, 5, 10, 15, and 20% of biochar, the cumulative methane and volume of biogas yields were, respectively, 17.04, 41.2, 43.8, 51.6, 48.6% and 150, 520, 680, 760, 690 . Comparing the cumulative methane production efficiency of the digester containing zero biochar (D0) with the addition of 5, 10, 15, and 20% biochar had more favorable effects and increased by 58.6, 61.1, 66.98, and 64.94%, respectively. From these results, adding 15% of biochar to anaerobic digestion causes a three-fold increase in methane compared to the control and more positive effects than all other biochar e compositions. According to this result, the right dose of biochar must be added to maximize biogas production.
