Construction and Feasibility Investigation of a Small-Scale Single-Basin Solar Still for Remote Areas

With the global fresh water shortages that limit readily accessible freshwater availability to only 0.5%, developing efficient and sustainable desalination technology has become essential. Traditional solar stills - often considered the oldest and most widespread desalination technique - often fail to achieve maximum output due to limited solar access and inefficiency. Passive desalination systems provide an attractive alternative for treating brackish and saline water in rural, energy-limited regions. In this research article, we review the performance of an economical single-basin solar still system (with 2 cm basin depth), in Khulna, Bangladesh during the winter season. This research investigates the efficiency of passive desalination systems at harvesting solar energy and turning it into distilled water, at an impressive daily average production rate of roughly $0.67 \mathrm{~L} / \mathrm{m}^{2}.day$. These findings have important consequences for dealing with water shortage problems worldwide, especially in regions that are sensitive to water pressure caused by climate change. This research highlights the potential of passive desalination technologies as a promising solution to address the increasing global need for freshwater, particularly in regions with limited access to energy and resources. It contributes to the existing information on these technologies and highlights their sustainable nature.
