Abstract

Solar distillation is an environmentally friendly method for obtaining fresh water through the utilization of solar energy. By using the sun's heat to evaporate and then condense water, this thermal application efficiently eliminates pollutants and impurities. This project focused on designing a Triangular Solar still that can increase water evaporation rates by using some agriculture waste which contains porous material. A few benefits of solar distillation are its sustainability, low maintenance needs and capacity to produce drinkable water from contaminated or saline sources. This project also focused on evaluating the design performance by monitoring and controlling all the factors that influence evaporation rates such as temperature, humidity, initial of water usage, solar irradiance, latent vaporization from solar energy and glass and wood materials of solar prototype. The combination of an Arduino Uno microcontroller, pH sensor, and water level sensor allowed for real-time tracking of clean water volume and quality. Experimental results show that, under daylight conditions and using specific methods, the triangular solar still produces almost 100ml of water with a pH level ranging from 5.48 to 6.8 using corn husks as a porous material. This method reduces the dependency on non-renewable energy and promotes the efficiency of natural resources.
