Abstract
One of the most commonly promoted, and used, water filters, in developing countries, is the Filtron ceramic filter. The most commonly used clay, in the production of the Filtron ceramic filter, is red clay. In the United States, Redart is the most commonly used and distributed red clay. Redart is mined by Cedar Heights in Ohio. Eight different clay body formulations were made for testing, each formula had different ratios of ingredients: Redart, sawdust, ball clays, play sand, and water. A total of 24 filters were produced, fired, and tested. Later, to compare flow rate performance, water was filtered through each filter for 3 consecutive days. The flow rates varied from 0.5 to 2 liters per hour.
