Abstract

The dual-slope solar tray-type desalinator was used to obtain treated water. The aim of this study was to evaluate the performance of the solar desalination water production with an external condenser and the physico-chemical characteristics of the water before and after the desalination process. Brackish water from the Sítio Alto dos Cordeiros well in the Queimadas municipality of Paraíba state was used as the source of water to be treated. The solar desalinator has an area of 4 m², with the solar desalinator control (D1) and the solar desalinator with external condenser (D2+C) used in the experiment. The saline water used in the experiment had an electrical conductivity of 1820 µS.cm-1 and a pH of 7.3. The most significant observed results were the maximum production of potable water on November 19, 2022, where a value of 8.6 L.day-1 was obtained for the solar desalinator with external condenser (D2+C), while the solar desalinator (D2) produced 7.61 L.day-1  and the external condenser produced 0.99 L.day-1  The solar radiation index was 874.8 W.m-2 for the two solar desalination units, and the saline water depth was 1cm. The results of the physical-chemical analysis of the brackish and desalinated waters showed a reduction in electrical conductivity of 99.07% for (D1) with a pH of 7.3 and 99.56% for (D2+C) with a pH of 7.3 on November 19, and a reduction of 99.45% for (D1) with a pH of 6.03 and 99.4% for (D2+C) with a pH of 6.4 on November 22 after the desalination process, reaching values in accordance with the potability standards required by the current Ministry of Health regulations in the country.
