Effect of using sponge pieces in a solar still

Solar distillation is a very effective way to obtain pure water, especially in isolated areas where the water is infected or polluted to obtain drinking water. Two conventional solar stills of the same size (0.5 x 0.5 m) were tested for 8 hours. One still is priced as an SSR reference still and the other still which contains pieces of sponge is SSM and that is the subject of our work. The results show that the use of sponge in winter improves the yield of 10 %

Small iron pieces effect on the output of single slope solar still

Solar distillation is an environmental technique that uses solar energy to treat polluted water. In this context, two solar stills of the same size (0.5 x 0.5 m) were exposed to the sun i.e., under the same weather conditions to see the effect of small iron parts on the production of pure water. The results showed that the modified solar still SSM which contained iron pieces had an improvement rate of 23.46% compared to the reference solar still SSR

Evaluating the Impact of Absorber Geometry on Solar Still Efficiency: A Comparative Study of Square and Round Absorbers

Solar stills have been used for many years in areas with limited access to fresh water, such as desert regions or remote locations. They are simple to construct using readily available materials and require no energy input other than sunlight. Additionally, solar stills are low-maintenance and can produce a significant amount of pure water with relatively little effort. Two solar stills are exposed to the sun, the first is a single solar still and the other is a hemispherical sender. Both stills have similar absorber. The purpose of this experiment is to compare the pure water output of the two devices. The finding shows that hemispherical solar still is more efficient than the simple solar still by 54.30 % in terms of pure water output. This suggests that the hemispherical still is better at capturing and utilizing solar energy to evaporate and condense water

The impact of the corrugated absorber shape on the performance of a hemispherical solar still for water desalination: an experimental study

Abstract Solar stills utilization has received great interest in arid isolated regions. In this study, experimental approaches have been investigated to prove the impact of the corrugated absorber shape on the hemispherical solar still performance. Four geometric corrugated shapes including present flat, triangular, semi-circular, square forms were tested for the corrugated absorber. Five hemispherical solar distillers have been fabricated and tested. The first distiller includes flat absorber (HSD-FA), the second distiller includes square corrugated absorber (HSDSA), the third distiller includes semi-circular corrugated absorber (HSD-SCA), the fourth distiller includes triangular corrugated absorber (HSDTA), and the fifth distiller is conventional (CHSD). The first and second distillers were compared with the CHSD on the first day. On the second day, the third and fourth distillers were compared with the CHSD as well. Experimental results obtained showed that, the total freshwater yield of the HSD-FA, HSDSA, HSDSCA and HSDTA were improved by 16.67, 27.08, 39.58 and 48.96%, respectively, compared over that of the CHSD. These results prove that the use of the triangular corrugated absorber shaped provides the highest thermal efficiency, and the optimum corrugated absorber shape is the triangular corrugated absorber shape
