Experimental Investigation of Various Factors Influencing Solar Still Production for Seawater Desalination

Abstract

With the abundance of water resources, freshwater availability is constantly decreasing worldwide. Seawater desalination is therefore given a lot of attention. Recently the use of renewable energy sources has grown significantly in the effort to reduce carbon emissions. Hence, the design, construction, and investigation of a single-slope basin solar still as a desalination system powered by renewable energy are the subjects of this study. To produce fresh water from seawater using a single slope solar still, experimental studies were conducted the effects of solar radiation, temperature variations, basin water amount, wind speed on daily production of the distillate output. Experimental results show that hourly distillate output and various temperatures increases with solar radiation intensity as a result hourly distillate output reaches to its maximum limit during noon time, when still receives maximum radiation. In addition to that basin water volume, and distillate output production are found to be having an inverse relation. Moreover, the daily production is affected by variations in wind speed and rises as wind speed increases.
