Potassium Permanganate


Potassium Permanganate KMn04

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.


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, 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.

Why Choose Hepure’s Potassium Permanganate?

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.
