An activated sludge system operates satisfactorily in the removal of organic load and factors such as dissolved oxygen concentration, pH, and turbidity should be monitored. Parte superior do formulário. The purpose of this study was to verify possible oscillations of these parameters. The monitoring was conducted for 43 days in May and June of 2014. Samples were collected on three points determined in the reactor and the analyzes were performed in triplicate. For pH, the values obtained were in the range 6.8 to 7.8. For dissolved oxygen, the value oscillated from 1 to 10 mg/L, but with more observations to 1 mg/L, which indicates that the process is operating efficiently, but for the days of higher concentration of dissolved oxygen, was observed the occurrence of tumid sludge, with a reduction of filamentous bacteria. For turbidity, it was found that for the three points of samples the profiles were similar, as one being activated sludge, occurs the complete mixture. During monitoring, the treatment system was operated without significant disruption thus ensuring the quality of the treated effluent.
