The discharge of sewage without any kind of treatment compromises the quality and generates imbalance in the receiving waters. One consequence of the inadequate sewage treatment systems is the persistence of pathogenic microorganisms and the selection of antimicrobial resistance strains. In this context, it is necessary to verify the performance of the effluent treatment systems in relation to the disinfection processes and the occurrence of multidrug-resistant microorganisms. Thus, the main objective of this project is to determine the concentration of total coliforms, Escherichia coli, Staphylococcus aureus and Enterococcus ssp. and detect the presence of Salmonella ssp. in two steps of a simulated black water treatment system: UASB reactor and photo bioreactor. Another goal of the project is to determine the profile of antimicrobial resistance using the pathogenic bacteria isolated from the system, which is installed at the Sewage Treatment Plant Monjolinho, in São Carlos (SP).
