This study addresses the persistent reliance of certain communities on groundwater for drinking purposes, despite its failure to meet quality standards due to the presence of harmful coliform bacteria. To meet these standards, a cost-effective and environmentally friendly filtration method is proposed, utilizing clay and rice husk as formative elements. The research focuses on creating a ceramic composite filter by blending rice husk with clay in varying compositions (30 %, 40 %, and 50 %). The mixture is processed into a paste, shaped into a green body, air-dried, and fired at different temperatures (875 °C, 900 °C, and 925 °C). Compression, porosity, and flow tests are conducted to evaluate the filter's performance. An increase in rice husk composition leads to higher flow rates, indicating improved water flow through the filter, suggests a positive influence of rice husk on the hydraulic characteristics of the filter material. The ceramic composite filter effectively filters coliform bacteria, achieving a 93 % reduction, although it falls short of meeting drinking water quality standards. The optimal sintering temperature is identified at 900 °C with a forming pressure of 30 MPa. This study emphasizes the potential of clay and rice husk-based ceramic filters as a viable option for improving groundwater quality, acknowledging their positive impact on porosity and flow characteristics. However, further refinement is required to fully align with established drinking water quality standards, suggesting avenues for future research and development in this critical field. This research explores the potential development of technology ceramic composite filter with the hope of making a positive contribution to advancing clean and sustainable energy solutions in the future
