“…Com os gráficos gerados e a aplicação do teste estatístico t de Student (SOKAL; ROHLF, 1970;ISAZADEH et al, 2015;SARTI, 2017), foi observado que as curvas simuladas e reais não foram estatisticamente iguais para nenhum dos parâmetros, tanto com o uso do modelo ASM3 original quanto com o ASM3 de Koch et al (2000).…”

RESUMO Neste trabalho, avaliou-se o uso do modelo matemático ASM3 para um sistema piloto de reator compartimentado anaeróbio/anóxico e aeróbio tipo MBBR, utilizado para a remoção simultânea de matéria orgânica e nitrogênio em esgoto doméstico. A simulação computacional foi implementada pelo software ASIM. Selecionou-se um conjunto padrão de parâmetros para o modelo, com uma combinação dos valores calibrados e dados da literatura. Com a modelagem computacional foi possível incluir as características operacionais próprias do sistema de tratamento e, embora o modelo não tenha tido sua capacidade de previsão dos parâmetros validada, foi possível verificar a aplicabilidade do ASM3 para as fases operacionais definidas neste estudo.

“…It is possible to promote the biological removal of nitrogen in treatment systems; however, the efficacy of the removal depends on the efficiency of the STS treatment. Regarding DO, it is a variable whose reduction might affect significantly the aquatic biota, and that in surface waters suffers influence of factors such as temperature and natural oxygenation, as well as the impact of organic matter 19 . The reduction in DO concentrations in point 4 is related to the input of the STS, which impacts the river both for its organic charge and for the disparity between the effluent flow and the river capacity.…”

The objective of this work was to evaluate the physicochemical parameters that express the water quality of the Rio Verde, in the city of Ponta Grossa, Paraná. Multivariate Analysis was used, and quality indexes were obtained, such as the Trophic State Index and the Water Quality Index for Aquatic Life Protection. River samples were collected at 4 points along the Rio Verde for 12 months. The study showed that the river presents a high trophic degree, and that it can be considered hypereutrophic, and that phosphorus concentration is determinant for this situation. The results indicated that, at point 4, downstream from the Sewage Treatment Plant, the aquatic environment is very poor for the biota. The disposal of the effluent was indicated as the cause, and it is assumed that the river has no flow capacity to receive this contribution, without suffering impact. It was also concluded that points 1 and 2 correspond to more preserved sites, but are not totally favorable to aquatic life either because they receive surface drainage from agricultural areas in the basin. Point 3, of urban character, suffers an impact caused by irregular connections of sewers, and contribution of streams that flow into the river.

a b s t r ac tThe performances of an anaerobic/aerobic baffled reactor (AABR) and a horizontal subsurface flow constructed wetlands (HFCW) have been investigated. In this study, both systems were operated in parallel using the same source of domestic low-strength wastewater ( in the HFCW. The AABR and HFCW achieved 78% ± 9% and 82% ± 9% COD average removal rates, respectively. To compare the results, a statistical test (significance level of 0.05) was used and showed no significant difference between the systems in terms of organic matter and total suspended solids (TSS) removal. In addition, this study addressed energy costs and treatment capacity per area for both wastewater treatment systems that were studied independently with capacities for 20 habitants, and showed lower energy consumptions per month when compared with a domestic electric shower generally used by a sample Brazilian family consisting of four members.
