Abstract: Humans need water to survive, but there are 1 billion people around the world who do not have access to safe drinking water. There are many risks associated with drinking unsafe water, most prevalently the risk of waterborne disease. The most applicable technology for remote communities is ceramic water filters (CWFs). CWFs most predominantly use size exclusion in order to remove bacteria from source water. This thesis investigated the performance of a new ceramic water filter. The filter is an 8-inch diameter ceramic disc placed inside a plastic apparatus. It offers a large surface area with strong resilience to breaking. Two different sacrificial materials were investigated at two different recipes. It was determined a ceramic disc made of 20% rice husk to 80% clay offers the most reliable and effective results. This design delivers water at a rate of 1.8-3.2 liters per hour while offering log removal values for E.coli of 2.4-6.1.
