Utilizing the dangled jute cords, reflectors, and condensation cycle to improve the double sloped distiller performance

The global water scarcity issue affects various regions, especially those distant from urban centers, making solar stills a vital solution. However, these systems suffer from limited productivity. This study investigates the operation of a cords wick double slope distiller (WDSSS) under different conditions. It examines the impact of varying cord counts (9, 16, 25, & 35 cords) and tests the influence of using reflectors and a condensation cycle with WDSSS. The results indicate that the optimal performance for WDSSS, both with and without reflectors and a condensation cycle, is achieved with 25 and 35 cords, respectively. Furthermore, at the 25-cord configuration, the WDSSS without the use of either reflectors or a condensation cycle demonstrated a 140 % increase in yield compared to a conventional solar still (7200 vs. 3000 mL/m².day, respectively). In addition, the WDSSS with reflectors and 25 cords exhibited an 180 % improvement in yield over the conventional solar still (9500 vs. 3400 mL/m².day, respectively). Moreover, at 25 cords, the combined effect of condensation and reflectors substantially boosted the WDSSS yield by 212 % compared to the conventional solar still (11250 vs. 3600, respectively). Finally, the highest performance of the WDSSS was achieved with reflectors and a condensation cycle using 35 jute cords, resulting in a remarkable 51.5 % increase in efficiency and a substantial 228 % increase in distillate yield.
