Acid mine drainage (AMD) is an escalating problem specifically in the Appalachian Region where water tends to contain high levels of metals such as iron and aluminum. In response to the increasingly prevalent issue of AMD, various counteractive options for cleaner waterways have been investigated. One treatment option to explore is using carbon nanotube (CNT) filters to decrease the concentration of metals in these AMD waters. Upon the creation of three different types of filters using double walled CNTs, single walled CNTs, and activated carbon through a suspension-filtering process, AMD waters with different temperatures, iron and aluminum concentrations, and pH values were run through the filters. Samples were analyzed for metal concentrations before and after filtration. The ultimate goal is to find the usefulness of these filters in treatment of AMD.
