Most Chosen for NAPL, Vadose Zone and Groundwater Chemical Oxidation

Pure-Ox is an in-situ chemical oxidation technology (ISCO) formulated to address NAPL, vadose zone and groundwater contamination.  The clean formulation is free of metals and other minerals which would remain after treatment.  The low cost of Pure-Ox makes multiple application possible, when necessary.

Pure-Ox is the most robust chemistry ISCO process with a high oxidation potential for contaminant destruction. Because it generates high levels of hydroxyl radical, superoxide radical, and hydroperoxide anion, Pure-Ox can destroy nearly all environmental contaminants of concern and provide enhanced treatment of adsorbed contaminants and nonaqueous phase liquids (NAPLs).  Applying as a dilute solution allows for the reactions to take place in the vadose zone.

2OH. + 2H+ + 2e–      2H2O Eo = 2.76v

H2O2 + 2H+ + 2e       2H2O Eo = 1.77v

HO2 + H2O + 2e       3OH Eo = 0.88v

Pure-Ox can be formulated to increase reactivity, lengthen activity and take advantage of natural occurring catalysts (iron, manganese, sulfur, …).  Simple laboratory testing can optimize Pure-Ox for each application also allow for field modification to enhance the ISCO outcome.


Pure-Ox is available in drums, totes, and tankers

Hepure is a key distributor of sodium and potassium permanganates to the environmental remediation
industry. In 2018 we supplied more than 200,000 pounds of sodium permanganate to dozens of
projects within the US and internationally.
Sodium permanganate is provided in 55 gallon drums and 265 gallon totes or tanker loads at full
strength (40%) or pre-diluted ready for use, by request.
Hepure has distribution facilities nationwide to minimize trucking cost and lead time.


Hydrogen Peroxide For Soil Remediation:

Hydrogen peroxide is a powerful oxidizer and can be used in soil remediation to break down various types of contaminants, particularly organic contaminants such as petroleum hydrocarbons, pesticides, and solvents. Here’s how it works:

  1. Oxidation of Contaminants: In the presence of a catalyst, hydrogen peroxide can generate highly reactive hydroxyl radicals. These radicals are capable of oxidizing and breaking down a wide variety of organic contaminants into less harmful substances, often into carbon dioxide and water.
  2. Enhancing Bioremediation: Hydrogen peroxide can also help improve bioremediation efforts by increasing the amount of dissolved oxygen in the soil. This can promote the growth and activity of aerobic bacteria and other microorganisms that are capable of breaking down organic contaminants.
  3. Fenton’s Reagent: This is a common method of using hydrogen peroxide for soil remediation. It involves the combination of hydrogen peroxide and an iron catalyst to generate hydroxyl radicals. Fenton’s reagent can be highly effective in breaking down many types of organic contaminants.
  4. In-Situ Chemical Oxidation (ISCO): This process involves injecting hydrogen peroxide directly into contaminated soil or groundwater. ISCO can be highly effective for treating large areas of contamination and for reaching contaminants that are deep underground.

However, the use of hydrogen peroxide for soil remediation must be carefully controlled. It can potentially react with organic matter and other substances in the soil, which can limit its effectiveness in breaking down contaminants. It can also potentially harm soil microorganisms if used in high concentrations.


Hydrogen Peroxide For Water Remediation:

  1. Oxidation of Contaminants: Hydrogen peroxide is a powerful oxidizer and can react with a wide range of organic contaminants in water, breaking them down into less harmful substances, often carbon dioxide and water. This can include pollutants such as certain pesticides, solvents, petroleum products, and more.
  2. Disinfection: Hydrogen peroxide can also be used as a disinfectant to kill bacteria, viruses, and other microorganisms in water. This is often used in combination with other disinfection methods in wastewater treatment.
  3. Advanced Oxidation Process (AOP): This process typically combines hydrogen peroxide with UV light or another catalyst to produce hydroxyl radicals, which are very potent oxidants. These radicals can oxidize a wide variety of pollutants, even those that are resistant to direct oxidation by hydrogen peroxide. This process is highly effective at breaking down a wide variety of contaminants and is often used in industrial wastewater treatment.
  4. Fenton’s Process: Fenton’s process involves the combination of hydrogen peroxide and an iron catalyst to produce hydroxyl radicals. This process is very effective at oxidizing many types of organic contaminants and can be used for treating wastewater.
  5. Increasing Dissolved Oxygen: Hydrogen peroxide can increase the amount of dissolved oxygen in water, which can support the growth and activity of aerobic microorganisms in bioremediation processes.
