Evaluation of Various Materials in Water Purification Projects

Abstract

The challenge of providing clean drinking water is becoming more pressing in the 21st century due to decreasing water resources, increasing populations, and the rising demands of both agriculture and industry. Although several water purification techniques exist, there is a growing focus on adopting more eco-friendly solutions. One such approach involves using solar stills, which offer a reduced carbon footprint. This research conducted an experiment to evaluate the efficiency of four different materials: wiry sponge, black volcanic rocks, coated metallic wiry sponge, and uncoated metallic wiry sponge. The experiment spanned five days, with performance measured hourly. Results indicated that the coated metallic material achieved the highest output, followed by the black volcanic rocks.
