Avaliação do potencial de reúso de águas cinzas utilizando aplicativo em uma comunidade rural dos sertões de Crateús-CE

Abstract

To increase water availability and minimize waste related to water uses, the reuse it is a technically viable tool to prevent or reduce conflicts generated by the growing demand for water. Especially in semi-arid regions, where the rainfall is low and there is an aggravating lack of basic sanitation. This study has as main objective to quantify potential of gray water to reuse in a rural community in the backlands of Crateús-CE. For this purpose, an application was developed and called TGWF Calculator, this application has an interface of a calculator, which, based on data of average monthly water consumption and the number of inhabitants per residence, calculates the flow of domestic sewage and the daily flow of gray water, in liters per day. Subsequently, the study makes a comparison of water consumption per person and the generation of gray water in the community with existing quantitative data. On the premise of creating quantitative technical support for the production of future works and for the application of reuse projects in the community itself. The generation of gray water in the community, presented an average value of 105.33 liters per day, which compared to the generation in the urban environment where the generation of sewage is considered higher, values in the range of 152.00 liters per day, can be considered high. Therefore, this study came to the conclusion that the community of Salgado-CE, produces a large amount of gray water suitable for reuse and has a high potential for the application of reuse techniques, and it is still necessary to carry out qualitative analyzes and monitoring according to current legislation to ensure proper treatment and future uses.
