“…Esta maior diferença de temperatura, ocorreu devido o maior índice de radiação ter ocasionado uma maior absorção de calor pela placa. Bouzaid et al (2019) relataram que um novo design do dessaliniador melhora a evaporação, aumentando o tempo de permanência da água salobra na placa de absorção.…”

Para o consumo humano e as demais atividades domésticas, os moradores do semiárido brasileiro utilizam águas de diversas fontes. Portanto, a análise da qualidade da água é de vital importância, principalmente por utilizarem águas de poços com alto teor de salinidade. Em contrapartida, é um território de elevada incidência de radiação solar, que é fundamental para a dessalinização via energia solar. Desta forma, nesta pesquisa foram realizadas análises físico-químicas de alcalinidade, cloreto, condutividade elétrica, dureza, pH, sódio e turbidez, com o objetivo de determinar a qualidade da água antes e após o processo de dessalinização solar, como também foi avaliado o rendimento do dessalinizador. As águas dessalinizadas apresentaram resultados muito eficientes na remoção dos parâmetros físico-químicos estudados, estando os mesmos de acordo com os padrões de potabilidade exigidos pela Portaria do Ministério da Saúde vigente no país.

In this study, a simulation was done to validate the experimental data of the new design of a cascade solar still, obtained from our existing prototype, for the climatic condition of Rabat, Morocco (34° 47′ N). The new design for the cascade solar still was developed using ANSYS FLUENT and modeled using FLUENT software. It has been found that the extracted data from the simulation's results are in good agreement with the experimental data. It was also examined that the productivity of the cascade solar still was higher from 12:00 to 15:00 h. This novel design of the cascade solar still ensures higher productivity than the single basin. Based on experimental results of the new design of the cascade solar still, the results show that the absorber plate temperature and productivity can reach more than 60 °C and 1.6 kg/m 2 h respectively. In comparison with the single basin, the plate temperature reaches more than 50 °C and the productivity 0.6 kg/m 2 h.

Solar still is a cost-effective and environment-friendly device to convert saline water into potable by employing solar energy in developing countries; however, it has an inferior thermal performance. This paper presents an attempt to improve energy efficiency and productivity of solar still by improving the design of the absorber plate. Modified solar still has been tested with a stepped-corrugated absorber plate. During the experimentation, it is found that the thermal performance of modified solar still is superior to conventional solar still. The average basin saline water temperature and the temperature difference between saline water and condenser glass cover are higher for stepped-corrugated solar still by 19.67 and 105.75%, respectively, as compared with conventional solar still. The average energy efficiency, exergy efficiency and productivity are found to be 259.61, 418.61 and 147.93% higher for stepped-corrugated solar still. Economic analysis indicates that the cost of distil water production is approximately Rs. 1.73 (0.023 $) per litre, and the payback period is 12 months, with carbon credits earned are approximately Rs. 11,998 (157.76 $).
