Short Description:

A solar still follows a relatively basic method of distilling water that is driven by the sun’s heat. Basically, solar desalination works on principle the same as that of rain. In a con- ventional solar still, the container is filled with saline water, which is evaporated by the sun through clear glass. Pure water vapor condenses on the top of the container and drips down the side. An inclined glass cover, supported by a suitable frame, covers the pan and is tightly sealed to prevent vapor leakage. A distillate collector runs down the lower border of the glass, collecting the water droplets and transporting them out of the enclosure through a plastic well-insulated tube. The water-filled pan is set on an insulating foundation. The study’s experimental component entails running the experiment with various sets of the system and operating parameters. 2

Idea Details:

Several coastal and distant places in modern times face a scarcity of safe drinking water sources. Traditional fossil fuels used to boil water are becoming scarcer by the day, ne- necessitating the usage of renewable energy sources to purify water. In order to enhance the performance of solar stills, a computer model was constructed utilizing relevant equations and data in this research. Solar irradiance, ambient temperature, wind velocity, and other factors influence the daily drinking water production rate of a still. Still, size, form, inclination angle, wick material qualities, insulation system, water depth, heat-storing media, and other factors influence production rate. The project’s biggest problem is the low output rate, which is dependent on natural conditions and still settings. Aside from that, costly installation and maintenance costs are major issues. As a result, the primary purpose of this study is to boost production rates and create a cost-effective still. The research is based on meteorological data from certain Bangladeshi locales.
