Conteúdo: | Abstract: The paper deals a case study of solid-liquid separation (SLS) approaches for swine manure biogas recovery in a system configured to treat solid fraction on Continuous Stirred Tank Reactor (CSTR) and liquid fraction on Covered lagoon biodigester (CLB) in a large scale. At the same time, scale down reactors on laboratory scale were operated under same conditions. Biogas productivity of full-scale CSTR showed an average of 0.65 ± 0.23 NLbiogas L-1 1reactor d-1, while CLB was around 0.18 ± 0.05 NLbiogas L-1reactor d-1. The results of lab-scale can predict digestion capability and methane recovery for full-scale system. Economy in biogas plant construction and operation, biogas generation constantly and digestate treatment system implementation are the mainly benefits to use SLS followed different reactor configurations. Biological desulfurization process was dependent of biogas retention time. By the way, operational improvements made on large scale have allowed an advance in the productivity and biogas quality.
