Chemical Oxidation: Sodium and Potassium Permanganate

Chemical Oxidation

Hepure is the industry’s leading provider of sodium permanganate (NaMnO4) and potassium permanganate (KMnO4) for in situ remediation projects which require chemical oxidation. When designing a remediation project, it is important to choose the right chemical(s) for site-specific conditions. Permanganate is commercially available in both potassium and sodium salts. Permanganate (MnO4-) is the active ingredient of both forms of the chemical, and thus has all the benefits of permanganates listed below. Contact us now and our product specialist will help guide you through the process of determining whether potassium permanganate or sodium permanganate chemical oxidation is right for your site remediation.

In Situ Chemical Oxidation (ISCO) with sodium permanganate and potassium permanganate is a safe, cost-effective and rapid remediation technology for the treatment of VOCs (e.g. PCE, TCE, DCE VC etc.) in groundwater, soils and sediments.
