The aim of this work was to evaluate the behavior of a laboratory-scale UASB reactor (16 L) in the treatment of textile biological sludge with biogas production, operating at different temperatures — 35 (mesophilic), 45 and 55oC (thermophilic) —, with constant hydraulic retention time of 24 h. The UASB reactor was able to treat the textile sludge, being positively influenced by increasing temperature, with greater removals in thermophilic temperatures and high removal rates of all monitored physical and chemical parameters: chemical oxygen demand (COD) (97% at 45 and 55oC), biochemical oxygen demand (BOD) (95% at 45oC and 94% at 55oC), total phosphorus (P-total) (95% at 45 and 55oC) and total nitrogen (N-total) (94% at 45 and 55oC). As for biogas production and methane concentration, the highest values were observed at 45oC. Based on the results, textile sludge treatability and biogas production in UASB are confirmed, with best performance at 45oC.
