Removal of Arsenic by Sorption to Iron-Coated Fibers

Evaluates the potential of iron-oxide-coated fibers as an arsenic treatment process for drinking water. Screens fibrous materials using isotherm data to identify the most promising material. Also assesses the ability of the iron oxide to be removed by physical processes, which would permit the fibers to be reused. Evaluates several alternative coating procedures and the most promising material and coating process in column tests to identify appropriate packing procedures and empty-bed contact times for use in a subsequent pilot study.
