Claims34
A method for reducing the concentration of a contaminant in water, comprising contacting water comprising one or more contaminants with a zero-valent iron treatment system for a time sufficient to reduce the concentration of the contaminant in the water, wherein the treatment system comprises a combination of one or more denitrification microorganisms and a zero valent iron composite comprising
- (a) a reactive solid comprising zero-valent iron and one or more iron oxide minerals in contact therewith, and
- (b) ferrous iron.
A zero-valent iron treatment system for reducing the concentration of a contaminant in a fluid, the system comprising a combination of one or more denitrification microorganisms and a zero valent iron composite comprising
- (a) a reactive solid comprising zero-valent iron and one or more iron oxide minerals in contact therewith, and
- (b) ferrous iron.
