Use of Phase Change Material (PCM) and Al₂o₃ Nanofluids in Pyramidal Solar Still

Distillation with a solar still has become increasingly important in extracting potable water from brackish and seawater in recent years. The partial accessibility of clean water supplies and abundance of water owing to prospective rehabilitation into drinkable water utilizing solar energy served as the inspiration for this work. The efficiency of pyramid solar still is investigated in this work. A distillation system with square pyramid fiberglass mounted on a black-coated Aluminum basin was created to attain this purpose. The solar energy that strikes the black-coated basin heats the water and evaporates it, generating vapors that condense to potable water on the fiberglass cover. The distillation system is used to test the performance of the still at different water depths, namely 5 cm and 10 cm, with paraffin wax material and preheated water. The experimental setup is positioned at a 50-degree angle from the horizontal. During sunny days, the hourly productivity of solar still with PCM is higher. According to the results of the experiment, when the still is operated with PCM at a depth of 5 cm, the efficiency of the still increases by 75%. Because of its thermal and economic qualities, nanoparticles A1203 are utilized as a storage material. The experimental setup is positioned at a 50-degree angle from the horizontal. During sunny days, the hourly productivity of solar stills with PCM is 170% higher. According to the results of the experiment, when using PCM, Nanoparticles A12O3, at a depth of 10 cm of water, the efficiency of still increases by 65 percent, and when using PCM at a depth of 5 cm of water, the efficiency increases by 75 percent.
