Track: Product Design and Development
The solar water purifier is an advancement of the current water purification system. It has been introduced to meet up demands of pure drinking water using renewable energy. It takes solar power as an energy source and stores it in a battery which is a free source of energy. Then using this energy, a low-cost heating coil heats water up to a certain temperature (below boiling temperature). After condensing cold water is further purified through the filtering chalk. In this stage, water is condensed again and gives water at room temperature. Through this process, we get pure drinking water. We followed almost all the phases of a product development process which started with collecting customer requirements and ended with finalizing the design. Cost analysis had also been done from the viewpoint of mass production of the product. We optimized the overall process using a metaheuristic approach for heating process, cooling process and purifying process. This product, if used properly, can eradicate the scarcity of pure drinking water.
