Dimensionamento de sistemas individuais alternativos de saneamento para área em Goiânia – GO

Abstract

According to data found in National System of Sanitation Information (2019), in 2018, Goiás has treated only 49,6% of the generated sewage. In this scenario, the intent of this paper is to dimension two alternative individual systems of sanitation – that are actions of sanitation accepted when the place is not served by the public sewerage system – for a delimited area inside Goiânia-GO. For that, it was adopted a descriptive research with a quantitative approach. Initially a search was done about four alternative individual systems of sanitation: Imhoff tank with sand filter; UASB reactor with low rate biological trickling filter and decanter; the combination of anaerobic, facultative and maturation lagoons and activated sludge process. The first two mentioned were chosen to be sized due the facility of operation and maintenance compared to activated sludge and due the lower area requirement for implantation compared to the lagoons. All sizing and analysis realized indicate that both treatments compared have satisfactory results to be used at the chosen area to review. I was possible to notice tha the implantation area was the data that most differentiated the alternative individual systems of sanitation, therefore, it would count a lot on a choice between the two. Another important factor to be observed to decide on a treatment instead of another is the implantation cost.
