Revolutionizing Water Purification: Advanced Membrane Technologies for Enhanced Solar Distillation

Abstract

Combining many strategies to increase evaporation rate can drastically change solar desalination efficiency. This study aims to investigate how to combine corrugated fins, blue metal stones, and evacuated tube solar collectors to maximize the water yield of solar stills (SS). An exploration was carried out to enhance the solar-driven evaporation rate of the system a six-tube evacuated solar collector. The idea behind corrugated fins was to enlarge heat transfer surface area between absorber and water. It was suggested to use blue metal stone to maintain the water's optimal temperature even under low-sun conditions. A full perspective is offered by separate displays of the hourly data and cumulative distillate output (DO) numbers for each period of time. The results show that, six months into the study, in May 2024, at 1 p.m. on a sample day, is when DO peaks. The average temperature of MSS is almost 26 °C greater than that of CSS, peaking at over 55°C. Furthermore, the total DO increases from 0.067 to 0.96 L at night and can reach 2.64 to 6.82 L during the day. Furthermore, the average DO improved by 146.3% during the course of the six months, rising from 3.02 to 7.22 L. Conversely, the MSS and CSS, respectively, 0.43 and 0.47₹/L. Modified solar stills reduced carbon dioxide emissions by a net amount that was exceeds conventional efficiency by 2.44 times.
