Abstract:This study evaluates the capacity of solids removal and biogas production from a new model of up-flow anaerobic digester created in Brazil. The anaerobic digester was loaded with cattle manure. Analyses of both affluence and effluent of an anaerobic digester were performed operating under field conditions, as well as the biogas production. The results showed that the anaerobic digester was loaded with an affluence with medium levels of total solids of 42.9 ± 9.5 g kg-1, and volatile solids of 30.2 ± 7.5 g kg-1, and its treatment process resulted in an average reduction of 24.78 ± 21.44% for volatile solids. Furthermore, there was a biogas production yield of about 0.52 ± 0.09 Nm3 kg-1 volatile solids. The biogas produced presented a methane concentration of 55.3 ± 2.1%. These results show that the up-flow anaerobic digester studied showed high yield of biogas production, but with low capacity for solids removal.
