This work aims to enhance productivity and reduce the production cost of conical solar distillers using green inexpensive materials. Conical stills are characterized by their cover is always exposed same radiation in all locations do not create shading. Different graphite bars installed at various distances still basin, acting as corrugated surfaces energy storage materials increase interface area, losses, overall performance. Three were designed tested investigate effect changing (0 30 mm) between rods on rate climatic conditions El Oued, Algeria. Furthermore, energy, exergy, economic, exergoeconomic approaches conducted assess viability proposed distillers. Results showed that reducing increases due increased interfacial space with basin water excess heat absorbed during day. The exergy efficiencies incorporated improved 46.23–90.46 % 181–321 respectively, compared traditional still. Based exergo-economic approach, annual outlets 45.65–90.46 187.5–439 yield payback period decreased 40.41–74.91 28.8–42.8 Finally, represent a good option for obtaining high performance economic benefit.

In this study, performance enhancement of conical distillers was investigated with various natural sand bed types. Four types different colors (compositions and concentrations chemical compounds) were tested used as thermal storage materials to reduce heat loss, enhance evaporation process, daily production. Three similar designed experimentally under the same climatic parameters over two consecutive days. Performance proposed distillers, including yield, energy, exergy, exergo-economic analyzed compared those reference distiller other related studies. Results showed that highest yield values achieved by combined a golden bed. The utilization achieves production 7.38 lm−2day−1 10.31 %, 22.79 35.91 60.43 % yellow sand, red white respectively. energy exergy efficiency golden, yellow, red, beds 59.59 44.84 30.33 17.85 143.52 103.44 64.73 36.39 respectively, higher than distiller.

This work aims to improve water productivity in solar stills by reducing heat loss through green composite insulators ensure storage of the absorbed thermal energy. Two materials were proposed and presented. The first is made date palm fiber mortar (PFM), second gypsum (PFG). Three identical distillers designed tested under same meteorological conditions El Oued, Algeria. reference case (RSW distiller) where a 5 cm thick wooden box used as insulation. (MSD-PFM insulated with 2.5 PFM material then installed inside box. third (MSD-PFG PFG conductivity was determined experimentally insulators. Results showed that accumulated production from MSD-PFG (4100 mlm-2day-1) higher than MSD-PFM (3400 RSW (2800 21.5 % 46.43 %, respectively. improvement efficiency 45.77 21.14 economic analysis cost (0.011 $/liter) (0.0153 31.68 4.97 sustainability, eco-friendliness, cost-effectiveness make it an attractive option for insulation applications distillers.
