Abstract

A filtration apparatus and filtration method can be used to reduce at least one contaminant (e.g., organic molecules, ions and/or biological microorganisms) in an aqueous fluid. The filtration apparatuses and methods of the invention can separate at least one contaminant from an aqueous fluid and/or oxidize at least one contaminant. In operation, an aqueous fluid is flowed through a filtration apparatus comprising a porous carbon nanotube filter material at an applied voltage. In some embodiments, the filtration apparatus described herein can be used for dead-end filtration. In some embodiments, the filtration apparatus described herein can be used for cross-over filtration.
