Abstract

"Ceramic pot filters (CPFs) have been proven to be an effective, low cost household water treatment system that are commonly used in third world countries. They are made using local clay, burn out material and colloidal silver or silver nitrate. Challenges faced by researchers include difficulty in acquiring filters from their manufacturing facilities without incurring damage and the cost of shipping. Acquiring the clay material used to make the filters is also difficult due to the cost of shipping and permits necessary to import soil. There have been studies conducted that compared laboratory made CPFs made with native clay and commercial clay bought in the U.S. However, there has been no attempt to identify the properties of native clays and identify a commercial clay or combination of commercial clays that may have similar properties and thus act as a representative surrogate. The purpose of this study was to characterize mineralogical and physically the properties of clay from Rabinal, Guatemala that is used to manufacture CPFs in Guatemala and develop a comparable engineered surrogate with commercial clays available in the U.S. Sand content, liquid limit and basic chemistry (mineralogy) were the parameters used to develop the engineered clay. Although several parameters are equivalent in the Rabinal and engineered clays, they are not an exact match. Flow rate data was the final property used to compare the two clays and the Rabinal filters were shown to have a higher flow rate than the engineered filters; however they were shown to have similar trend and slope over time"--Abstract, page iv.
