“…A constant and continuous solar radiation needs to be reached to the solar still for maximizing its water productivity. Badran and Abu‐Khader 92 and Almuhanna 93 theoretically and experimentally proved that the water productivity increases along with increase in intensity of solar radiation. Figure 3 shows the summarized graph of hours of the day (h) versus intensity of solar radiation (W/m 2 ) reported by various researchers.…”

Purified drinking water is the basic need of human beings. Purification of water assisted by freely available solar energy can be the best alternative compared with other water purification techniques available in the market today which consume nonrenewable energy. Distillation, which is the most ancient method, is being used for water purification. The device in which solar thermal energy converts brackish water into pure drinkable form is known as a solar still. Present article reports an extensive study of numerous designs of solar stills. The article also includes a review of effect of each parameter that influences the water productivity that is, pure water.Considerations of thermodynamics, heat transfer, and mass transfer are also explained in brief. The reviews of various kinds of analysis namely, theoretical, experimental, computational, cost, and water quality have been reported.

“…Os autores Al-hinai, Al-nassri e Jubran (2002) estudaram à influência da radiação solar no desempenho do dessalinizador solar com cobertura de vidro de inclinação única, com produção máxima às 13h:50min de 0,5 L.m -2 .h -1 , conforme a Figura 4. Almuhanna (2014) também inferiu que a produtividade de água destilada é maior à medida que a intensidade da radiação solar aumenta. parâmetros, como radiação solar, velocidade do vento, temperatura ambiente e alterações de perda de calor na produtividade, concluindo que a radiação solar é parâmetro mais essencial para o processo.…”

Dessalinizador solar é um equipamento ancorado em tecnologia viável e de baixo custo por utilizar a energia proveniente do sol. Além disso, apresenta resistência a altas temperaturas, podendo obter água potável. O objetivo deste trabalho é estudar a influência dos parâmetros construtivos do desempenho térmico de dessalinizador solar. Para atender este objetivo, optou-se por uma descrição sequencial dos fatores que interferem no processo de destilação solar. Os resultados desta revisão indicaram que a dessalinização solar é afetada pela área de evaporação, profundidade da lâmina da água e do ângulo da cobertura do dessalinizador. O isolamento do sistema de dessalinização afetou positivamente a produtividade, porque aumentou a capacidade de aquecimento e os efeitos evaporativos dentro do dessalinizador. Também verificou-se a partir dos estudos observados que o desempenho do dessalinizador é aprimorado através do aumento da radiação solar, temperatura do ar ambiente, temperatura inicial da água na bandeja e velocidade do vento. Além disso, o desempenho foi associado à condutividade térmica dos materiais utilizados na produção do dessalinizador, e para taxa alta de produtividade dessalinização ser alcançada usando materiais absorventes térmicos, como uso de aletas, nano fluidos e esponjas integradas no dessalinizador. Portanto, concluiu-se que os parâmetros climáticos e operacionais inerentes ao dessalinizador solar, foram fatores determinantes para melhoraria da produtividade de água dessalinizada.

“…The function of the condenser was to provide a surface temperature (inside surface of the inner tube) lower than the dew-point temperature of the water vapour. Consequently, the condensation process and the phase-change of water vapour into freshwater were accelerated, as mentioned by Almuhanna (2014).…”

“…In Saudi Arabia, distilled water is the main source for domestic consumption, and this use of distilled water is one of the highest in the world (Aljohani, 2004). The water produced by a solar distiller is pure and is suitable for residential applications (Almuhanna, 2014). Furthermore, solar distillation is a safe and economical method for the purification of water (Swetha and Venugopal, 2011).…”

“…Moreover, combining the solar still with an air-conditioning system can increase the condensate output from the solar still (Abdel-Rehim and Lashine, 2012). In a recent study, Almuhanna (2014) improved the productivity of a single-slope solar still by combining the solar still with a condenser supplied with cooled water from an evaporative cooling system. The connection of the solar still to the condenser increased the production of stilled water and the volumetric thermal efficiency by 55.41% and 30.1%, respectively.…”

To performance comparative studies, three sets of integrated solar still double-slope (SSDS) were constructed and examined under hot, humid and dusty climatic conductions of Al-Ahsa (eastern province), Saudi Arabia. The SSDSs were identical in all aspects but the first set was without condenser (SSDS), the second one with condenser (SSDSC), and the third set with condenser and solar water heater (SSDSCSH) in order to raise the brackish water temperature before entering the solar still. The condensers were provided with cold water from an evaporative cooling system reservoir. Experimental results revealed that the distilled water production from the three distillers SSDS, SSDSC, and SSDSCSH, respectively, was 1.98, 4.82, and 6.65 litres per square meter per day with volumetric thermal efficiencies of 18.7, 46.0 and 64.4%. The integrated double-sided solar distiller with condenser only (SSDSC) increased the production of distilled water and the volumetric thermal efficiency by 143.4% and 146.0%, respectively, as compared with (SSDS). The solar water heater connected to the third set (SSDSCSH) increased the basin water temperature resulting in increasing the evaporation rate and the production of distilled water. Therefore, this system increased the production of distilled water and the volumetric thermal efficiency by 38.0% and 40.0%, respectively, as compared with the second set (SSDSC). Moreover, the third set increased the production of distilled water and the volumetric thermal efficiency by 235.9% and 244.4%, respectively, as compared with the first set of solar stiller (SSDS) The accumulated of atmospheric dust on the glass cover of solar distillers reduced the production of distilled water and efficiency by 63%. Therefore, the cleanliness of the solar still glass cover was crucial to provide and maintain the maximum production. Ultimately, The pH, EC, and TDS of the distilled water were found to be much lower (7.8, 42.9 s/cm, and 39.7 ppm, respectively) than those of the brackish water (8, 1417 s/cm, and 1392 ppm, respectively).
