“…Shahid et al [21] with the rapid expansion of industrial civilization came energy needs of 1.3% per year. Hasanuzzaman et al [22] reported that chemical dyes like thymol blue and orange methyl improved the still performance by about 53% and 44%, respectively. Alfred Blaszczky et al [23] in the study of the sustainable growth of cells dyed by black chokeberry, bomas, and leaves, cells dyed with synthetic N719 sensitivity were found to perform better with surface dyes.…”

The typical solar still with internal and exterior heat transfer was used to test the impact of mixing various colours into the basin water. This is well-known that enhancing distillation involves adding black dye to basin water. Identical design parameters create two single-slope basin-type solar stills (effective area 0.5 m2). This study conducted experiments to add black, green, blue, and red dyes to basin water during the winter for 24 hours. For more than a month, the amount of distilled water recovered per hour, with varying temperatures and solar activity (May 2021). This research aims to (i) examine the effect of various dyes with basin water on the internal and external heat transfer and performance of the system and (ii) study the effect of adding dyes into the basin water on increasing energy balance by the solar system. This is indicated by the fact that the introduction of colours into the basin water has a major impact on external and interior heat transfer. The evaporation, radiation, and heat transfer rate from liquid to glass significantly impact how well the filtration system works.

“…Figure 10 expresses the variance of experimentally achieved hourly thermal efficiency with respect to time from 8.00 to 17.00 hours for water flows of 1.4, 1.7, and 2 LPM, respectively. The maximum hourly thermal efficiency has been estimated to be 53%, 51%, and 64.1% for water flows of 1.4, 1.7, and 2 LPM, respectively, for a saline depth of 0.05 m. 15.00 hours, the thermal efficiency per hour was maximum when the brine temperature was maximum, and the base of the tank was at 15.00 hours [26] .

The performance of the double-slope solar distiller is combined with two types of solar collectors (vacuum tube solar heater ETC and solar concentrator PTC). The water inside the solar distiller is heated by a heat exchanger linked with the solar heater and the concentrator. 1.4, 1.7 and LPM 2). The results showed that the high temperature of the brine water inside the distillate was obtained at the LPM 2 flow, while the productivity was 2.248, 2.774, and 4.367 liters / day, respectively, for a depth of 0.05 meters of brackish water for the three flows, respectively. The maximum thermal efficiency capacity per hour was 53%. And 51% and 64.1% for water flows of 1.4, 1.7, and LPM 2, respectively. 15.00 hours the thermal efficiency per hour was maximum when the brine temperature was maximum and the base of the tank was at 15.00 hours.

“…Additionally, Thymol Blues produces a bit more than orange methyl. The productivity of the insulated distiller is also much higher than that of noninsulated distillers (Abed et al, 2022). Copper Condenser (Nehar et al, 2022) was also a method of enhancing the productivity of the CSS by about 7.5% with cost-effectiveness by 55% than the CSS.…”

The desalination process is important for converting seawater drinking water in many arid regions of the world. Solar stills are considered one of the best economical solutions to overcome the shortage of water despite of the limitations in its productivity. In this research two, similar solar stills were designed and fabricated and different absorbing materials were used to increase productivity and enhance the still’s performance. These materials are luffa, black luffa, fine steel wool and, steel wool pads and the performance of the two solar stills were evaluated at the same climate conditions. Different parameters were measured such as the still productivity, solar intensity, temperature, and wind velocity to calculate the still thermal efficiency and the exergoeconomic analysis. The results concluded that the still productivity was about 1.872, 2.923, 3.325, 3.712, and 4.384 l/m2 for conventional solar still (CSS), solar still with luffa (CSS-NLF), with black luffa (CSS-BLF), with fine steel wool (CSS-FSW) and with steel wool pads (CSS-SWP) respectively. The thermal efficiency ratings were roughly for the comparable values 17.13, 21.22, 24.71, 28.60 and 32.74% respectively. In addition, the cost per liter (CPL) for these solar stills was about 0.0082, 0.0058, 0.0049, 0.004,4 and 0.0034 $/l/m2 respectively. Finally the payback period and the exergoeconomic analysis were performed and evaluated for these modifications and the findings cleared that using steel wool pads showed a promising performance compared with the other modifications.
