Resumo
Basic sanitation of water and sewage is fundamental for the quality of life of the
population in both the urban and rural regions. This work presents a technical,
economic and environmental analysis of the current scenario of an effluent generated
in a sports club located in the city of São Paulo. Its current sewage treatment system
was analyzed and, knowing the infrastructure available for it, the results obtained
from water and effluent samples submitted to laboratory tests performed at the club's
facility were interpreted through technical analysis reports from the club effluent
carried out in 2017. The emission of an effluent from a place or establishment for
disposal to the environment is considered satisfactory when it meets the parameters
of Decree No. 8,468, of September 1976 - Art. 19 A, which deal with the effluent
emission standards for launch in the public sewer system (SABESP). Through a
literature review on types of effluent treatment available in Brazil this work presents,
through a case study, suggestions for technical, environmental and economic
improvements related to the operation and installation of effluent treatment in the
club in question using Upflow Anaerobic Sludge Blanket (UASB) for effluent
treatment. The main technical advantages are the reduced use of physical area for
this process and the satisfactory efficiency of BOD removal (biochemical oxygen
demand) that contributes to the reduction of contaminants in the effluent when
returned to the environment. As a conclusion, the elaborated study presented
possibilities of continuity after the built treatment station, through a monitoring to
analyze its eco-efficiency related to the reuse of water.
