“…In this process, the evaporation rate was improved due to the temperature difference between the top cover and the basin liner was increased. Kabeel et al [27,28] experimentally studied the jute cloth knitted sand energy storage material in the solar still to augment the evaporation for desalination. The capillary action by the jute cloth and sand energy storage in the distiller were produced of 5.9 kg/ m 2 day.…”

Solar energy is one of the most powerful sources for many sustainable applications. Recently, efficient water distillation has attracted significant attention. The fresh water productivity depends on how efficiently the system harvests the incoming solar energy and converts it into useful heat. In the present work, nano-coated absorber plates (NCAPs) were examined in the single slope solar still (SSSS) for clean water production. The NCAPs were CuO, MoO 3 and ZnO, respectively. The CuO-NCAP was fabricated with the thermal evaporation method while the radio-frequency Magnetron Sputtering technique was used to fabricate the MoO 3 and ZnO NCAPs. The attained particle size of the CuO, MoO 3 and ZnO are 30-34 nm, 25-30 nm and 30-35 nm, respectively. The sphere (CuO), plate (MoO 3), and wedge (ZnO) like morphologies are identified with field emission-scanning electron microscope. All the NCAPs and reference solar still were tested under the same environmental conditions. The climatic parameters (solar influx, ambient temperature and wind) and SSSS's temperatures including water temperature (T w), internal air temperature (T int-air), inner cover (T ic), outer cover (T oc), and absorber plate temperature (T NCAP) were measured at 30 min intervals with the help of Type-J thermocouples. Herein, we present an evaporative heat transfer (h ew), efficiency, and cost analysis of the SSSS with CuO, MoO 3 and ZnO-NCAPs. Three different feed waters fetched from the surface well water, hill side well water and hill side pond water were used in this work for evaporation. The result reveals that the evaporation of conventional single slope solar still, CuO, MoO 3 and ZnO NCAPs were 2.1 l/m 2 day, 2.9 l/m 2 day, 2.7 l/m 2 day and 2.6 l/m 2 day, respectively.

“…Hybrid PCMs were prepared using nanographites at a 20% maximum concentration by weight. This resulted into a 94.52% improvement on the distillate production compared to a solar still with PCM alone (Kabeel et al, 2019a). The addition of graphene oxide nanoparticles improved the thermal performance of a PCM based solar still by 52% and a corresponding saline water temperature increase of 7 • C. The total distillate produced for the nanoPCM system was 5.62 kg/m 2 (Kabeel et al, 2020).…”

Solar distillation system depends on adhesion of water molecules inside the glass cover of solar stills. Regular glass surfaces are prone to adsorbing other unwanted compounds and in turn lower the percentage of recovery of pure distilled water. In this study, the production of purified distilled water was compared with and without the use of graphene-based surface modifiers. In areas where salt content is high, the first pass is still usually laden with salts. Hence, to improve adhesion of water and rejection of salts, both the inside glass cover surfaces and the metal absorber plates were modified using oxygen plasma treatment and graphene surface enhancement. Results showed a 48.9% improvement of distilled water recovery from an initial recovery of 2.90 L/m 2 per day to an average of 4.32 L/m 2 per day. In addition, the resulting distilled water passes the World Health Organization drinking water standards such as pH, electrical conductivity (EC), and salinity. The average reduction in EC was 96.52%, an average increase of 5.06% of pH, and an average reduction of salinity of 96.52%, all measured at the highest brine salinity of 5%. The reported value of EC was 23.33 µS/cm, a lowest and near-neutral pH of 6.85, and an average salinity of 12.10 ppm.

“…Based on the results, V model was cheaper and more effective. Kabeel et al described the impact the combined use of graphite Nano‐particles and paraffin waxes has as phase‐change materials on solar water desalination system performance. The findings revealed that the daily efficiency of solar water desalination system would increase from 51.41% to 65.13% by increasing the volumetric percentage of nanoparticles from 5% to 20%.…”

Summary In the present experimental research, a five‐stage solar still was investigated using phase change material paraffin wax. Owing to Iran's climatic conditions and its location in a dry area and nonexistence of fresh water sources, producing this water from saline water sources is essential. In this research, thus, a multistage solar still was planned and examined as a commonly used freshwater source via (phase change material) paraffin wax. On the back of the collector absorber plate, paraffin wax (phase change material) was used as an additional energy source for the sun. The volume of water produced in different thicknesses of 2.5 cm, 5 cm, and without PCM was investigated. The study results specified that the application of phase change material paraffin wax in the thickness of 2.5 cm agent led to a 15% increase in freshwater production. The quantity of water generated in the flow rates of 0.7, 1.3, and 1.8 L/min was also studied. The highest quantity of water produced was obtained in the 1.3 L/min flow rate. Moreover, the quantity of water generated in the five stages of the desalination process was separately measured that the highest amount of production was associated with the first stage.
