Abstract	The removal of Total and Volatile Suspended Solids (TSS & VSS, respectively), is a key parameter to assess the performance of UASB (Upflow Anaerobic Sludge Bed) reactors. TSS and VSS removal is associated with the Hidraulic Retention Time (HRT) and the amount of anaerobic sludge in the reactor. Bacterial growth is constant in biological reactors and periodic discharges of excess sludge have to be performed. In this work, results obtained in a pilot-scale UASB reactor treating pre-settled sewage from the city of Salta, Argentina, are presented. Excess sludge discharges did not affect significantly the quality of the effluent. Treatment efficiency (as TSS and VSS removal) was greater than 80% as long as the sludge height in the reactor was higher than 1 m. The optimum HRT was 6 h. TSS and VSS removal efficiency could be an operational criterion to decide the frequency for excess sludge discharges in full-scale UASB reactors.
