Solar still is the emerging technique to distilled water at places where there is a huge scarcity of drinking water. The current investigation deals with the productivity enhancement of distilled yield of conventional solar still (CSS) to obtain decontaminated fresh water. Experiments were conducted by modifying CSS for five different cases viz: (a). Conventional solar still without the wick, (b). Conventional solar still with the tilted wick at 15˚, 30˚, and 45˚ (c). Black painted basin conventional solar still (BPBCSS) with the tilted wick at 30˚. All experiments were performed on the month of March for approximate same climatic condition. From the preliminary investigation, the flow rate of basin water on the wick was kept fixat 0.2g/m2.secin such a way that the wick remained completely wet. The overall daily productivity of the caseswas found to be 3.802kg/m2, 3.925kg/m2, 4.25kg/m2,4.102kg/m2, and 4.372 kg/m2 for CSS without the wick, CSS with the tilted wick at 15˚, CSS with the tilted wick at 30˚, CSS with the tilted wick at 45˚, and BPBCSS with the tilted wick at 30˚ respectively. For BPCSS, the cost of the obtained yield distillate was found to be ₹1.38 per Liter, making it more affordable than CSS.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
