About technology:

  • nZVI – nanoscale Zero Valent Iron,
  • Elemental iron (Fe0) nanoparticle suspension (sol),
  • With a strong tendency to oxidation, high reducing power,
  • Ability to split carbon-halogen bonds in pesistent compounds,
  • The final products are an inorganic halogenids and rapidly decomposing hydrocarbon fragments: significantly reduced the risk!,
  • Nano-scale grain size range, 1 nm = 10-9 m. (the diameter of human hair is 80000 nm!),
  • Small particles high specific surface high reactivity,
  • Move in the pore space with water molecules, high mobility and penetrating ability,
  • Eco-toxicity cannot be detected.

                                      

Mobile production equipment:

  • Rapid, on-site technology to produce the appropriate amount of nZVI,
  • Reduced transportation costs,
  • Most efficient maintenance of reducing capacity,
  • Fully automated / programmable equipment,
  • Capacity: ~1m3/hr 50000 ppm nZVI.

                                                    

Application:

  • Breakdown of persistent, halogenated hydrocarbon compounds in subsurface environment (soil and groundwater contamination),
  • Targeted and effectively delivered into the pore space with in situ technology (ie. direct-push injection),
  • Main application for high concentration plume, and former source zones,
  • Combinable with anaerobic microbiological degradation methods (eg. reductive de-chlorination) in case of low concentration plume area.

Officially certified treatable contaminants (field applications, experience):

  • Chlorinated aliphatic hydrocarbons (CAHs):
    • Chloroethylenes (PCE, TCE, DCE, VC)
    • Chloroethanes (TCA, DCA, CA)
    • Chloromethanes (CM, DCM, CF, CT)
  • Chlorinated aromatic hydrocarbons:
    • Chlorobenzenes (MCB, DCB, TCB, TeCB, PeCB, HeCB)
    • Chlorophenols (MCP, DCP, TCP, TeCP, PCP)

Potentially treatable pollutants (literature experiments):

  • Polychlorinated biphenyls (PCBs)
  • Polychlorinated dibenzo-dioxins (PCDDs)
  • Polychlorinated dibenzo-furans (PCDFs)
  • Chlorinated pesticides (DDT, pCPA)
  • Inorganic chlorine compounds (perchlorates)
  • Metal contaminants (As, Cu, CrVI)
