“…Most global water is not drinkable as it is highly saline (Katekar and Deshmukh, 2021b). Water in rivers, lakes, ponds and ground wells is also not potable as human activities pollute it (Katekar and Deshmukh, 2020c). Polluted water affects the health of humans and animals (Katekar and Deshmukh, 2020a).…”

This study examines the Washim district’s socioeconomic growth to determine the criteria for district development. This study found that the Washim district comes under the rural area, where the child sex ratio is inferior. Even in some villages, it has zero value. In some regions where the Scheduled Caste (SC)/Scheduled Tribe (ST) population is more, the child sex ratio is less. Out of six sub-districts, four sub-districts have a low literacy rate (less than 75%). The mean literacy rate is found as 81.7%, and its standard deviation is evaluated as 7.0. In the region where the literacy rate is higher, people are less busy with farming, and hence the percentage of the cultivator is less and vice versa. In the region where SC and ST population is more, the percentage of Household Industry (HHI) worker is higher and vice versa. Out of 698 inhabited villages, 692 villages are electrified in the district, with 99.1% of towns having installed power supply. The use of liquefied petroleum gas (LPG)/piped natural gas (PNG) is minimal in the Washim district. In the region where firewood availability is accessible and adequate, the use of LPG/PNG is found to be less than its average value.

Solar stills are known as one of the best and most efficient methods for water desalination. Due to low production of solar stills, researchers have been using experimental and theoretical methods to come up with possible solutions for ameliorating freshwater production through these systems. This study aims to investigate the performance of a single slope solar still combined with a v-grooved solar air heater. Important parameters (height of the v-grooves, length of the collector, and air mass flow) affecting the performance of the proposed system were mathematically investigated using MATLAB software. The average deviation between the experimental and theoretical results was found to be about 7%. Furthermore, the results showed that the water production rate and the efficiency of the modified solar still were 150% and 44.20% higher than those of the conventional ones, respectively. Two new correlations were proposed based on the experimental results in order to predict the water production via solar stills, which are in good agreement with the results of the existing models. Based on the obtained results, the increase in the inlet air mass flow rate was not conducive to water production as the production rate was reduced by 60%. In addition, through the economic analysis, the cost per liter for the modified still was determined to be 0.03 [Formula: see text] with an interest rate of 10%.

The configuration of an external solar dish improves the performance of stepped slope solar still (SS) in an experimental setting. The use of an external solar dish raises the effects of the water basin, resulting in a higher rate of evaporation. The stepped still was designed, built, and tested in Ismailia, Egypt, using local weather conditions. The proposed SS had a 1 m 2 base area and eight steps, a solar dish with a concentration ratio of 80, a cone tank, two centrifugal pumps, four photovoltaic modules totaling 1000 W, a control unit, and solenoid valves. The impact of utilizing the storage material during the phases was investigated. A nozzle was installed at the top of the cone tank. Four mass flow rates of circulated water were examined 250, 350, 450, and 550 mL/min. The control unit receives inputs from the photovoltaic output, photodiodes, and water temperature inside the cone. The control unit outputs the signal for the two solar dish motors, centrifugal pumps, and solenoid valves. First, a standard stepped SS, second, a stepped SS using phase change material (PCM), and finally, a stepped SS using PCM combined with a solar dish were investigated. The conventional stepped SSs with PCM had an optimal mass flow rate of 250 mL/min, whereas the stepped SS integrated with the solar dish had 550 mL/min of mass flow rate (an optimum value). The highest daily freshwater productivity was 7.63, 9.18, 11.23, and 13.9 kg/d for water spraying mass flow rates of 250, 350, 450, and 550 mL/min, respectively, with 0.0161 $/L/m 2 of a maximum projected cost, according to data from an integrated stepped SS.
