This study was aimed to conduct an analysis of the efficiency of pollutant elimination in the Dobra treatment plant, which operates based on the SBR reactor. The object purifies domestic sewage and pre-treated industrial sewage from a slaughterhouse within the Dobra municipality. The source material for the analysis comprised the values of pollution indicators: BOD5 , CODCr, total suspended solids (TTS) in raw sewage (19 samples) and treated sewage (34 samples). The results of chemical analyses were obtained in the period 2007-2014. The results were compared with the limit values imposed by the Regulation (2014). The coefficient of reliability of the treatment plant was also calculated in this study. The average efficiency of pollutant elimination in the treatment plant was: BOD5 - 98.6%, CODCr - 94.9%, total suspended solids - 97.6%. These results demonstrate that the studied facility operates flawlessly and the treatment efficiency is high. On the other hand, the reliability coefficient values indicate that the operation of this object is unstable.
