Efficient Water Distillation Using Double-slope Solar Still with External Heating Mechanism

Abstract

Access to clean and safe drinking water is a critical concern, particularly in areas where water sources are contaminated, such as coalmine regions. This abstract presents an innovative approach to efficiently distill and treat contaminated/coalmine water using a double slope solar still with an external heating mechanism, incorporating a pre-filtration tank. The proposed system begins with a pre-filtration tank designed to remove suspended solids, sediment, and other impurities present in the contaminated water. This initial treatment step aims to enhance the overall efficiency of the distillation process by reducing fouling and potential damage to the solar still components. The treated water from the filtration tank is then channeled into the double slope solar still. This solar still configuration incorporates two sloped glass covers arranged in a V-shape, optimizing solar energy absorption, and facilitating condensation. The double slope design ensures efficient utilization of solar radiation throughout the day, while the V-shape configuration helps direct the water vapor towards a central collection channel, enabling effective separation of impurities. To further enhance the distillation process, an external heating mechanism is integrated into the system. A heating element positioned beneath the solar still basin provides a steady temperature gradient, promoting faster evaporation rates and improving overall productivity. This external heating mechanism accelerates the distillation process, enabling efficient purification of contaminated/coalmine water. Experimental results demonstrate the superior performance of the proposed system in treating contaminated/coalmine water compared to conventional methods. The combination of the double slope solar still, pre-filtration tank, and external heating mechanism yields significantly higher distillation rates and improved water quality, effectively removing contaminants and impurities. The presented system offers a sustainable and cost-effective solution for treating contaminated/coalmine water, addressing the specific challenges associated with such water sources. Its adaptability and scalability make it suitable for deployment in coalmine regions or areas with similar water quality issues, providing communities with access to clean/drinking water. In conclusion, the double slope solar still with an external heating mechanism, coupled with a pre-filtration tank, represents an innovative approach to efficiently treat contaminated/coalmine water. The system's ability to remove impurities through filtration and subsequent distillation offers a reliable and sustainable solution for water purification in challenging environments. Further research and development efforts are essential to optimize the system and promote its practical implementation on a larger scale.
