“…In comparison to previous concise literature and recent work (Diab et al 2022(Diab et al , 2021Essa et al 2021), incorporating rotating discs in a vertical distiller significantly increased the distillate yield of the still. In this study, the scholars aimed to investigate the impact of varying water levels on still performance to answer some critical questions: "would the distillate yield of the modified distillers be enhanced if the water depth was increased?…”

The ability to get clean water is the most urgent birthright for human beings. The scarcity of safe drinking water is a major challenge in both developed and developing countries. Due to overpopulation, industrial revolution advancements, and agricultural evolution, this challenge has become crucially influential. Several studies on solar desalination are being conducted to create novel models that will improve the efficiency and production of these units. Because of their higher evaporation, condensing, exposure, and output rates than traditional stills, vertical distillers have lately piqued the interest of numerous academics. In this study, the scholars investigated the impact of varying water depth at the best rotating speed of discs from their earlier work (1.5 rpm) on the thermal productivity of vertical distillers. Numerous water depths (5, 8, 11, and 14 cm) were studied at 1.5 rpm to specify the best depth. The results indicated that utilizing moving discs enhanced the distillers' productivity. Besides, the peak distiller performance was obtained at 1.5 rpm and 5 cm. Furthermore, the yield of the modified single-stage vertical distiller (MSSVD) and modified double-stage vertical distiller (MDSVD) was increased by 350 and 617.4%, respectively, over the conventional tilted distiller (CTD) productivity of 2.3 L/m2 day. MSSVD and MDSVD had the highest efficacy rates of 48.4 and 77.2%. Lastly, for CTD, CVD, MSSVD, and MDSVD, the pure water cost was 0.025, 0.0477, 0.0180, and 0.0193 $/L, respectively.

Access to clean water is being limited throughout the globe day by day. Several illnesses are caused by water supplies that are contaminated or not distilled. Immediately people's necessity is to purify water without impacting the environment. Solar distillation is an extremely clean distillation in a water treatment procedure. Solar still is among the methods for water purification that produce potable water. Several atmospheric and operational factors require the still lay-out to be augmented. As is commonly known, the vertical sides of the SS become hotter as solar radiation hits them, and the high temperature area resulted in considerable energy losses to the surroundings. To increase the profitability of solar stills, researchers have investigated a variety of models. Throughout its experiments, the solar still with rotating components has been regarded as a reliable and efficient system. Throughout this comprehensive review, we presented, clarified, and analyzed the status of various techniques used to reduce losses of back wall of solar stills solar distillers, for instance rotating wick, vertical wick, drum, trays, discs... etc. Diverse outcomes (highest daily output & improvement) demonstrated the significance of rotating parts, including vertical wick distiller (7.2 L/m 2 /d & 154%), moving wick solar still (9.17 L/m 2 /d & 315%), drum distiller (9.22 L/m 2 /d & 350%), and vertical disc distiller (16.5 L/m 2 /d & 617.4%).
