Heavy Metal by Zero-Valent Iron and Natural Zeolite Partitioning in Acid Mine Drainage: A Comparative Study

Abstract:

In this study, two different bed materials in media filter systems were examined. Natural zeolite has the ability to take up heavy metals (Cd, Zn) from acid mine drainage (AMD) as well as zero-valent iron (ZVI). The aim of the study was to estimate the ability to remove heavy metals of Natural zeolite and compare the efficiencies of the two media. A major purpose of this report was to determine which media would have a higher permeation rate after running a period of time. It was concluded that ZVI had a higher efficiency of taking up heavy metals (>96.5%) and a faster permeation rate which had a longer operating life.
