The potassium permanganate oxidant is delivered as a dry powder >97% pure and mixed with water at room temperature up to a 5% solution for injection. The powder can be diluted on site and, for larger quantities, can be mixed and delivered to the site in a tanker truck via our site-ready solutions service. As potassium permanganate is more difficult to mix on site, off-site blending is often preferred for this oxidant. Hepure is the premier potassium permanganate supplier so we can answer any and all questions you might have about our product.
Potassium permanganate is a pH neutral solution that does not release gas or create heat during reaction with contaminants. Further, potassium permanganate can be added to excavation pits before backfill to treat groundwater flowing back into the excavated area. This is a great way to ensure that your remediation project is successful.
In addition to the variable packaging and delivery options, as a potassium permanganate distributor, Hepure can assist with preparation and maintenance of CSAT paperwork for potassium permanganate projects. Our clients not only enjoy the benefits of product reliability and cost effectiveness, but also the support to complete their projects successfully in a timely manner.
|Assay||Specific Gravity||Bulk Density||Form|
|≥97% KMnO4||2.70 at 15° C||Approximately 100 lb/ft3 Decomposes at approximately 150° C||Dark purple to bronze crystals with no odor|
The results speak for themselves: independent laboratory tests consistently show that Hepure’s potassium permanganate is the purest product available on the market for groundwater and soil remediation.
Quality matters – and the quality of the amendments used in your site remediation efforts are of particular importance. What gets put in the ground can remain in the ground. That is why we regularly test all of our products to identify trace metals that could be harmful to your groundwater chemistry and why we offer only the purest chemical oxidants available for in situ remediation.
Analysis of trace metals covers a wide array of elements, and Hepure places emphasis on a few key metals: arsenic, chromium, mercury, and lead. These are of particular concern in the remediation of contaminated sites as they are often part of the contaminant list, which is why we focus on ensuring that these metals are well below specifications.
Hepure’s potassium permanganate is also all available as a pre-mixed solution in concentrations up to 5%. This both eliminates on-site health and safety issues and greatly simplifies an important task required for on-site injection. Click here to learn more.

Potassium Permanganate Water Treatment:
- Oxidation of iron and manganese: Potassium permanganate can oxidize dissolved iron and manganese, turning them into solid particles that can be filtered out of the water. This is particularly important in well water, where these elements can be common.
- Disinfection: Potassium permanganate has a disinfectant quality. It can inactivate bacteria, viruses, and other potentially harmful microorganisms in water.
- Removal of organic matter: KMnO4 is often used to oxidize organic compounds, including some types of organic contaminants such as phenols and other harmful chemicals. When the organic matter is oxidized, it breaks down into smaller, less harmful components or into particles that can be filtered out.
- Taste and odor control: Potassium permanganate can be used to control the taste and odor of water. It achieves this by oxidizing compounds that cause unpleasant tastes and odors.
- Removal of hydrogen sulfide: Hydrogen sulfide gas can be present in water and cause a foul, rotten-egg odor. KMnO4 can oxidize this gas to form yellow, insoluble sulfur that can be removed by filtration.
Potassium Permanganate Soil Remediation:
- Oxidation of organic compounds: Potassium permanganate can be used to oxidize a wide range of organic compounds, such as chlorinated solvents (e.g., trichloroethylene or TCE), polycyclic aromatic hydrocarbons (PAHs), and certain pesticides. Upon oxidation, these complex organic compounds are broken down into smaller, less harmful substances.
- In-Situ Chemical Oxidation (ISCO): This is a process in which chemicals like potassium permanganate are injected directly into the contaminated soil. KMnO4 reacts with the contaminants and breaks them down. It can be used for in-situ chemical oxidation (ISCO) treatment of soil and groundwater contaminated with certain types of organic pollutants.
- Metals Immobilization: While it’s not a primary method, KMnO4 can also be used to transform certain heavy metals in soil into less mobile or less toxic forms, limiting their ability to leach into groundwater or be taken up by plants.
- Odor Control: Similar to water treatment, potassium permanganate can be used to control odors in contaminated soils, especially those associated with reduced sulfur compounds, by oxidizing these compounds.
