Development and Performance Evaluation of a Portable Ceramic Water Filter with Exfoliated Graphite and Sawdust As an Additive

The availability of safe drinking water in non-networked rural areas and disaster-affected zones is dependent on point-of-use water filters. This study describes the design and performance assessment of a personal portable ceramic water filter named “sip-up.” Four sample variants were made using clay, exfoliated graphite (EG), and sawdust as raw materials. Samples were made using a mold to ensure uniformity and sintered at 850 °C. The experimental results showed that the sample containing the maximum amount of sawdust had the highest porosity of 36.07 ± 1.8
