| Resumo: | Reliability is the probability that an item performs its function adequately, in accordance with specific conditions, for a set period of time. Therefore, it is essential that the processes of sewage treatment be evaluated in relation to reliability, thus providing information that allows subsidizing the selection of a particular treatment system, in addition to allowing the evaluation of the actual performance of a WWTP. In this context, this research investigated three (3) different sewage treatment routes of WWTPs operated by the Company of Water and Sewage of Ceará (CAGECE) evaluating the efficiency results and reliability tests (considering a value of 95%). It was observed that the system composed of UASB Reactor accompanied by Submerged Aerated Filter (SAF), achieved a better-quality effluent in terms of COD removal and better data homogeneity. On the other hand, the route of Extended Aeration Activated Sludge Process obtained the best performance in relation to the ammonia removal, behavior expected by this type of technology. Finally, it was verified the reliability analysis is a tool to be applied in the monitoring of WWTPs, emphasizing the importance of these studies for the decision making for the technological choice of new plants design. |
