Abstract
Systems and associated methods for treating contaminant-containing wastewater are provided. The systems generally include a reducing zone for reducing the oxidation-reduction potential of the water and a clean-up zone comprising zero valent iron for removing at least a portion of the contaminant from the contaminant-containing water. The systems are operable to remove one or more contaminants from the contaminant-containing water and are operable for extended durations without clogging due to the formation of iron hydroxides.
Claims11
An ex-situ system for treating contaminant-containing water, the system comprising:
- a first treatment zone comprising a reducing agent adapted to reduce the oxidation-reduction potential of contaminant-containing water flowing therethrough;
- and
- a second treatment zone downstream of the first treatment zone, the second treatment zone comprising zero valent iron for removing at least a portion of contaminants contained in the contaminant-containing water.
