EZVI-CH4™ Antimethanogenic ISCR Technology for DNAPL Treatment
Antimethanogenic EZVI-CH4™ uniquely combines the proven chemistry of the National Aeronautics and Space Administration’s (NASA) EZVI Technology with the selective power of Provectus’ Provect-CH4® methanogen inhibitors to yield a genuinely new, antimethanogenic DNAPL technology that is capable of direct in situ destruction of source materials. It provides:
- Provect-CH4™ methanogenic inhibitor (blended within fermentable H donor component of EZVI)
- Matching physical chemistry (hydrophobic) enables complete miscibility (contact) with DNAPLs
- Sequestration (phase partitioning) of hydrophobic contaminants (e.g., halogenated hydrocarbons) into outer liquid oil membrane
- Mass flux reduction from source areas due to dramatic decrease in water solubility of contaminants
- Food grade soybean oil as a slow release, long term H donor
- Powdered, highly reactive, ZVI (< 5 µm size distribution) encapsulated within water/VO micelles (not in direct contact with ground water) will only react with contaminants that are hydrophobic
- Abiotic reactions primarily occur in the aqueous interior of emulsion where ZVI is suspended in water
- Biotic reactions primarily occur on the exterior of the emulsion and down gradient (hydrologically) of the EZVI implementation zone
EZVI-CH4 is the only technology engineered to directly destroy DNAPL while significantly decreasing the wasteful consumption of hydrogen donor by actively controlling the production of methane.
