EVALUATION OF METHANOGENIC ACTIVITY AND POTENTIAL METHANE GENERATION FROM ORGANIC WASTE SUBJECTED TO ANAEROBIC CO-DIGESTION

Abstract

He present job has by aim study he performance of production of biogas in L/ kgSV in mixtures of the organic fraction of urban waste, with bovine excreta (EB) that was used as inoculum. They were carried out essays of Methanogenic Biochemical Potential (MBP) with 3 different mixture percentages by volume (“Test 1”: 50% RO-50% EB; "Rehearsal 2”: 25% FORSU-75% EB; "Rehearsal 3”: 12.5% FORSU- 87.5% EB), the which HE were done in duplicate. For assess Yeah exists performance improvement of biogas HE added biochar of peel of hazelnut for assess Two groups were used: Group A (mixtures without biochar ) and Group B (mixtures with biochar ), with their respective duplicates, considering the previous mixtures. The research showed that the mixtures with biochar and a higher cow manure content (25%) FORSU and 75% EB with biochar ; and also 12.5% FORSU and 87.5% EB with biochar ) they had older productions of biogas with 423.47 and 253.57 L biogas/kg of SV respectively, By it so much, he use of biochar generated a 67% increase in biogas production in Trial 2 Group B and 27% increase in biogas production in Trial 3 Group B in the co-digestion of FORSU and EB.
