NanoFeTM: AN INNOVATIVE REMEDIATION TECHNOLOGY FOR SOILS AND GROUNDWATER
- NanoFe are submicron (<10-6m) nano particles of zero valent iron
- NanoFe rapidly destroys recalcitrant contaminants in-situ or ex-situ. This is based on the redox process where the contaminant serves as the electron acceptor
- NanoFe can be injected by gravity or under pressure

TREATABLE BY NanoFe TECHNOLOGY
CONTAMINANTS:
Halogenated aliphatics
(TCE, PCE, DCE, VC)
Halogenated aromatics
PCBs
Halogenated herbicides & pesticides
Nitroaromatics

ADVANTAGES OF NanoFe TECHNOLOGY
- Treats both the dissolved plume and source areas
- No depth limitations
- Highly reactive – rapid degradation and no toxic intermediates
- Portable – low capital and O&M costs
- Easily injected; NanoFe flows with groundwater
- Low NanoFe / contaminant ratios required
