Resumo: The goal of this research was to obtain and withdraw the kinetic parameters from an Upflow Anaerobic Sludge Blanket – UASB in removing the organic load from the waste by-product of a dairy activity. The treatment system was composed of a Sand Interceptor (Grit Chamber), Grease Intercept Chambers, Stirred Contact Tank (CT), a UASB reactor, Anaerobic Filter (AF), and Batch Activated Sludge System (BASS). The HRT (Hydraulic Retention Time) and temperature were: 44, 35, 30, 26 and 20 hours, after the system stabilization phase, with a temperature range varying from 24.8 ± 1.8oC. The reactor volume was 394 L. From the COD (mg L-1) data, COD t (mg L-1), Total Fixed and Volatile Solids (mg L-1), Temperature (oC), Flow rate (L day-1), and Sludge Profile (Total Volatile Solids, mg L-1), monitored along all the research period in a pilot scale in each, the study was conducted in order to obtain the following kinetic parameters: yield coefficient ‘Y’ ‘(mg DQO mg SVT-1 d-1), the decay coefficient ‘Kd’(d-1), and maximum growth rate ‘μmáx’(d-1) and the limited growth rate ‘Ks’(mg DQO L-1). The determined kinetic parameters were based on linear regression studies, giving technical support to the physical-chemical data collected during system operation.
