Operação de filtros biológicos percoladores pós-reatores UASB sem a etapa de decantação secundária

Abstract: ResumoA pesquisa teve por objetivo avaliar filtros biológicos percoladores (FBP) pós-reatores UASB operando sem a etapa de decantação secundária, em termos da remoção da demanda bioquímica e química de oxigênio (DBO e DQO) e sólidos suspensos totais (SST). O aparato experimental consistia em um reator UASB que alimentava quatro FBP em paralelo, preenchidos com diferentes materiais suporte. O reator UASB operou em regime hidráulico permanente, e três condições operacionais foram impostas aos FBP durante o perío… Show more

“…The overall efficiency was compromised by the low performance presented by the UASB reactor in this study. However, when we evaluate the final effluent in terms of BOD, efficiency is compatible with that of the literature (Almeida et al 2011;Bressani-Ribeiro et al 2018), reaching 91%. At this point, it is important to highlight that such efficiency was obtained without the presence of a secondary clarifier.…”

“…Therefore, we can see that EPS proved to be another alternative material that could be used in sewage treatment. The quality of the final effluent has always been within the limits of several global laws and compatible with materials used in sewage treatment plants at a full scale that use patented materials (Tonetti et al 2019), and also compatible with studies that used alternative materials (Almeida et al 2011).…”

“…A remoção de DBO via UASB é mais de 60% mais eficiente do que a feita por decantadores primários, além disso, o sistema apresenta-se mais simples devido à baixa demanda energética e menor complexidade de equipamentos. Hoje os filtros percoladores continuam sendo utilizados, tendo como principais meios suportes pedras, plástico ou espuma (WANNER et al, 2006;BRESSANI-RIBEIRO et al, 2018;ALMEIDA et al, 2011).…”
