Abstract

Water scarcity is a constant reality in several regions, especially in the Brazilian northeast, due to its semi-arid climate. One of the solutions found is desalination, which converts brackish water into drinking water. The objective of the work is to analyze the technical-economic issue of a six-stage thermal desalination prototype, coupled to thermosolar energy in the northeastern semi-arid region, for the production of drinking water. To develop the research, the Meteonorm 7.1 climatic and solarimetric database was used, the R program, statistical software for compiling data and reports from the state's freshwater program. The results demonstrated that with 6 stages of the desalination plant it was possible to obtain 60 liters/day of desalinated water, in a collector area of ​​4 m², the daily production of drinking water was directly linked to the intensity of solar radiation, with values ​​of 6 to 7 kWh/m². Subsequent analysis of water from the thermal desalination process showed a significant reduction in STD, from 8,998 mg/l found in brackish water to 48 mg/l in desalinated water. The price of producing a liter of drinking water through the desalination system was R$0.17. The return on investment in this desalination plant with an invested capital of R$ 10,000.00, has an average payback of 4 years and 9 months. It can be concluded that the present study aimed to demonstrate the various benefits in implementing an autonomous water desalination system coupled to thermosolar energy for the northeastern semiarid region.
