In the study, the Weibull reliability theory was used to analyze the reliability of a small Sequencing Batch Biofilm Reactor (SBBR) for domestic wastewater purification. Also, the relative frequency and probability of exceedance of effluent discharge limits for the analyzed pollution parameters (BOD5, COD, total suspended solids, total nitrogen and total phosphorus) were determined. Full technical scale tests were carried out at a facility with a mean throughput of 0.6 m3/d, for a period of 34 months from December 2016 to September 2018. An analysis of the test results regarding the reliability of removal of the contaminants to the maximum effluent discharge levels yielded the following figures: BOD5 – 77.5%, COD – 97.8%, TSS – 100%, TN – 12.2% and TP – 21.7%. The relative exceedance frequencies measured in treated wastewater, expressed as proportion of all measurement series for a given parameter were: BOD5 – 17.14%, COD – 3.7%, TSS – 0%, TN – 85.2% and TP – 81.2%. The study showed that the small SBBR system was reliable in removing the basic contaminants (TSS, BOD5, COD) from domestic wastewater, but did not ensure effective removal of biogenic compounds. Large-scale use of this type of treatment plants may contribute to the eutrophication of wastewater receivers.
