Sodium Permanganate

Sodium permanganate’s active oxidant is the permanganate anion (MnO4-), is proven safe and cost-effective for many applications, including soil remediation and water treatment. Compass’ sodium permanganate is available in 20% and 40% solutions, as well as custom blended concentrations.

Our permanganates are tested for trace metals to ensure we are providing only the purest sodium permanganate for your in situ remediation projects.

Delivery of sodium permanganate is available in totes and drums at standard concentrations, as well as custom blended solutions delivered directly to your site in totes and bulk tankers. This eliminates the need for on-site mixing of permanganates and removes many of the health and safety concerns that go along with mixing in the field.

Our team has extensive experience in working with even the most difficult project sites and makes your project logistics a priority. We understand that your projects are time and resource sensitive.

Using Sodium Permanganate in Remediation

Both sodium permanganate and potassium permanganate are well-suited for many remediation applications as they do not require activation, are applicable over a wide pH range, and their presence is easy to detect in monitoring wells.

In situ chemical oxidation (ISCO) using permanganates is a proven remediation technology that is safe and cost-effective. The active oxidant is the permanganate anion (MnO4-), a strong oxidant which can persist and react with COCs several months after injections are complete.
