Desalination Of Saline Water Using Phase Changing Materials And Nanoparticles
The most necessary resource for humanity to sustain life on earth is water, which can obtain from nature. The availability of usable water for all purposes is decreasing day by day and it has been turned out to be a great challenge for entire human race. The only available water resource in large quantities is the sea water. Many researches and experiments all over the world had been done to convert the sea water to usable water. This research plan intends to reach the same target by using solar stills to transform seawater to drinkable water. While the solar still is already in use, this work aims to produce more quantity of drinkable water during both day and night using Paraffin wax as a phase change material(PCM) and coconut shell powder as Nanoparticle which act as an insulating material to effectively transfer the heat only into the solar still side. The experiment was categorized into three parts: first in a conventional solar still, then with PCM, and finally with PCM-Nano particles, and the findings are compared. The experimental setup of this solar still is completely economical to operate and more efficient than the normal version because of the addition of PCM and nanoparticles. Based on the experimentation the results showed that there is a significant rise in the output around 4% when using PCM and output increased to 8-10% , this increase is due to addition of Nanoparticles below the PCM which reduces any heat loss from beneath the set up.
