Performance Investigation of a Cascade Type Solar Still for Water Desalination

Abstract

Solar still is one of the most economical and effective way of desalinating the abundant sea/brackish water into drinking water. Solar desalination system is producing clean water from brackish water in desert regions with limited electricity. The present study concerns experimentally with the performance of cascade type solar still. The literature suggests that the addition of inside and outside reflectors, absorber materials, and outside condensers can improve the basin type solar still's absorption, evaporation, and condensation processes. It has a made a cascade type solar water desalination system. Design device is solar based and more environment friendly. This device is applicable for desalination, purification. The experimental setup for this investigation was successfully finished utilizing PVC tubing, MS sheet, black oxide, transparent glass, and a wooden frame. The output is distilled water, with a maximum volume of 130–135 ml at 12 p.m. for 16-days period from April 3, 2024 to April 18, 2024. According to the plotted graph, the amount of distilled water increased from 11 a.m. to 2 p.m. during the course of these 16 days, ranging from 80–90 ml to 100–110 ml. A few drawbacks include realistic black coating that disrupts absorption and pipe leaks. Cascade type solar water desalination system is more useful but not at the top level. So increasing its performance it has become much more productive, less costly & environmental friendly other conventional solar desalination system.
