Development of Point of Use Household Water Purification SystemUsing Locally Sourced Clay Material

Abstract

Access to clean and safe drinking water remains a critical challenge, particularly in low- and middle-income countries. This study focused on the development of a point-of-use household water purification system utilizing locally sourced clay material. The clay, collected from Imiegba in Edo State, Nigeria, was molded into ceramic filters and fired to create a porous structure essential for filtration. The system's effectiveness was evaluated by testing water from the Omouku River before and after filtration, with analyses conducted for physicochemical parameters, heavy metals, and microbial contaminants. Results indicated significant improvements in water quality, including the complete elimination of heterotrophic bacteria and reductions in heavy metal concentrations. The study underscores the potential of locally available materials in providing a sustainable and affordable solution for improving access to safe drinking water in regions with limited resources. Recommendations include regular monitoring, community education, and further research to optimize the filtration system's performance.
