PermeOx® Ultra

PermeOx® Ultra is a specially formulated grade of engineered calcium peroxide providing extended oxygen release for enhanced aerobic bioremediation. Containing at least 18% Active Oxygen, PermeOx Ultra is available in a powdered and granular form.

Permeox Compare
  • PermeOx Ultra powder allows for a workable slurry for injections and does not set up
  • PermeOx Ultra Granular reduces dust hazards and material handling issues in the field

 

Studies have shown that PermeOx Ultra releases more oxygen into the subsurface environment over extended periods as compared to other soil remediation products. PermeOx Ultra can continually release oxygen for over 350 days, thus providing a useful and cost-effective tool for enhancing the aerobic bioremediation of petroleum hydrocarbons and some non-halogenated organics. 

PermeOx Ultra is formulated to contain ≥ 18% Active Oxygen (AO), a measure of how much oxygen is available to be released. This compares favorably to the AO levels found in typical calcium peroxide and magnesium peroxide based oxygen release products that are subject to lock up/encapsulation. This means that on a pound to pound basis, PermeOx Ultra is able to deliver more oxygen.

  • Releases oxygen for up to one year, which is the longest oxygen release profile of similar products in the market
EXAMPLE CONTAMINANTS
  • BTEX
  • Petroleum Hydrocarbons
  • Non-halogenated organics
TECHNOLOGY: AEROBIC BIOREMEDIATION

Aerobic Bioremediation technologies are used to accelerate the degradation rate of petroleum hydrocarbons and some fuel oxygenates through natural biological processes. By adding oxygen to the subsurface through pure oxygen injection, use of oxygen releasing compounds, hydrogen peroxide infiltration or ozone injection, the oxygen becomes available to aerobic microorganisms in the unsaturated zone, saturated zone or both. The process helps to facilitate the conversion of biodegradable compounds to CO2 and H2O. This technology can be used to effectively reduce contaminants from oil, petroleum, gasoline, solvents and pesticides, among others.

  • Contaminants Treated

    Chlorinated Solvents

    • Vinyl chloride
      -

      Vinyl chloride

      An organochloride used chiefly in the production of polyvinyl chloride (PVC) and may be a daughter product formed during the reductive dechlorination of TCE and DCE. Solubility in water 2.7 g / L and a Kow of 15. It is a known human carcinogen and causes liver damage. MCL of 2 ppb.

    BTEX

    • Benzene
      -

      Benzene

      A colorless and highly flammable liquid with a sweet smell, it is a natural constituent of crude oil, an aromatic hydrocarbon, and one of the most elementary petrochemicals. The greatest use of benzene is as a building block for making plastics, rubber, resins and synthetic fabrics like nylon and polyester. Other uses include: as a solvent in printing, paints, dry cleaning, etc.

    • Toluene
      -

      Toluene

      An aromatic hydrocarbon and a constituent of crude oil and gasoline, widely used as a solvent. Solubility in water 0.47 g / L and a log Kow of 2.73. May form light non-aqueous phase liquids (LNAPLs). Little carcinogenic potential. MCL of 1 ppm.

    • Ethylbenzene
      -

      Ethylbenzene

      A highly flammable, colorless liquid with an odor similar to gasoline. The greatest use — more than 99 percent — of ethylbenzene is to make styrene, another organic liquid used as a building block for many plastics. It is also used as a solvent for coatings, and in the making of rubber and plastic wrap.

    • Xylenes
      -

      Xylenes

      An aromatic hydrocarbon consisting of a benzene ring with two methyl substituents, Xylenes are mainly produced as part of the BTX aromatics (benzene, toluene and xylenes) extracted from the product of catalytic reforming known as "reformate".

    PAHs

    • Naphthalene
      -

      Naphthalene

      The simplest polycyclic aromatic hydrocarbon, it is a white crystalline solid with a characteristic odor that is detectable at concentrations as low as 0.08 ppm by mass. Most naphthalene is derived from coal tar.

    Oxygenates

    • Methyl tert-butyl ether (MTBE)
      -

      Methyl tert-butyl ether (MTBE)

      Derived from fossil fuels and almost exclusively used as a fuel component in fuel for gasoline engines.

    • Tert-butyl alcohol (TBA)
      -

      Tert-butyl alcohol (TBA)

      Derived commercially from isobutane as a co-product of propylene oxide production, it is used as a solvent, ethanol denaturant, paint remover ingredient, and gasoline octane booster and oxygenate.

    Petroleum Hydrocarbons

    • GRO (gasoline range organics)
      -

      GRO (gasoline range organics)

      A colorless liquid with characteristic odor that is found in petroleum and used as a fuel and a solvent; it reacts with strong oxidants, which generates fire and explosion hazard.

    • DRO (diesel range organics)
      -

      DRO (diesel range organics)

      An oily, colorless liquid, that is used as a solvent, in organic synthesis, as a distillation chaser, in jet fuel research, in manufacturing of paraffin products; and in the rubber industry, paper processing industry, and a component of gasoline, which may result in its release to the environment through waste streams.

    Chlorobenzenes

    • Chlorobenzene
      -

      Chlorobenzene

      Chlorobenzene will enter the atmosphere from fugitive emissions connected with its use as a solvent in pesticide formulations and as an industrial solvent. Releases into water and onto land will dissipate due to vaporization into the atmosphere and slow biodegradation in the soil or water.

    Fluorinated Compounds

    Miscellaneous

    • Acetone
      -

      Acetone

      A colorless, mobile, flammable liquid, and is the simplest ketone, that is mainly released into the environment from industrial activity, but also is naturally released from plants, trees, volcanic gases and forest fires.
