Desenvolvimento e análise de um dessalinizador solar tipo tanque com teto removível.

Abstract

The scarcity of good quality water still affects many places in Brazil, especially the Northeast region, which, in addition to problems with water supply, still suffers from the high salinity of its water bodies. Despite the scarcity of water resources, the region has good availability of solar radiation for most of the year. Thus, this work aimed to develop and analyze a tank-type solar desalinator, in order to reduce the amount of salts present in the water, in addition to evaluating the efficiency of the desalination process. For this, a prototype was made using materials that are easily accessible and at the lowest possible cost, available in the local market. For the analysis of the desalinator, temperature sensors were implanted both inside and outside, in order to monitor it throughout the day. In addition, the local temperature and incident radiation were also collected. The water desalinated during the process was collected in a container and measured at the end of each day. The efficiency of the desalination process was evaluated by the reduction of total dissolved solids in the water. The desalinator showed a production of 1750 ml of water and an efficiency of 22.89% on the day with the highest incident radiation, values considered satisfactory, while the reduction in total dissolved solids was 99%, proving the efficiency of the desalination process.
