Sodium Permanganate

Sodium permanganate — 40% NaMnO₄ liquid, dark purple; supplied in drums, totes, and tankers, full strength or pre-diluted.

Sodium Permanganate Supplier

Sodium permanganate orders tend to be the big ones. Hepure is a key distributor of sodium and potassium permanganates to the environmental remediation industry — in 2018 alone we supplied more than 200,000 pounds of sodium permanganate to dozens of projects in the U.S. and internationally — and the logistics behind that are the part most callers care about: 55-gallon drums and 275-gallon totes for smaller programs, tanker loads for larger ones, at full strength (40%) or pre-diluted and ready to inject, from distribution relationships positioned nationwide to minimize trucking cost and lead time.

Sodium permanganate (NaMnO₄) is a liquid chemical oxidant used to treat chlorinated solvents in soil and groundwater. It delivers the same permanganate ion (MnO₄⁻) as potassium permanganate, with identical oxidation chemistry — but at 40% by weight versus about 5% for a dissolved potassium solution, it is far easier to use and more flexible for injection. It is the permanganate of choice when high-concentration delivery and minimal water handling are the priorities. See how the two compare and the wider permanganate line.

ISCO with Sodium Permanganate

In situ chemical oxidation with sodium permanganate is a safe, cost-effective, and rapid remediation technology for chlorinated ethenes — PCE, TCE, DCE, and vinyl chloride — in groundwater, soils, and sediments; it has long been used by wastewater treatment plants as well as in remediation. Permanganate typically stays active for a few weeks to a few months depending on site conditions, and successful applications come down to one thing: achieving contact between the oxidant and the contamination. Size the order to the formation’s demand, not just the contaminant’s — our permanganate demand calculator is built for exactly that.

Three field properties make it a good fit for sites where underground utilities and equipment can’t be affected by the injection solution: it is pH neutral, and it releases no gas and creates no heat as it reacts. And a fourth that consultants appreciate at the monitoring wells — the solution keeps its dark purple color until it reacts with contamination, so the extent of distribution is easy to see.

Why Choose Hepure’s Sodium Permanganate

Quality matters, and the quality of the amendments used in your remediation matters most of all: what gets put in the ground can remain in the ground. Hepure regularly tests every product through independent laboratory analysis to identify trace metals that could be harmful to groundwater chemistry, with emphasis on the four that are so often on the contaminant list themselves — arsenic, chromium, mercury, and lead. Independent testing consistently shows Hepure’s sodium permanganate to be among the purest available for groundwater and soil remediation.

Common Questions

Sodium or potassium permanganate? Same chemistry, different logistics. Sodium for high-concentration injection with minimal water handling and no CFATS paperwork; potassium for lower cost, soil blending, and dry-crystal handling. Our full comparison walks through it.

Can I dilute the 40% solution on site? Yes — it dilutes easily with water to the design concentration. For larger volumes, ordering it pre-diluted is usually simpler and safer than mixing in the field.

What’s the sodium concern? Every gallon carries sodium into the aquifer. On most remediation sites it’s a non-issue; where soils are sodium-sensitive or SAR is monitored, it belongs in the design conversation — and can tip the choice toward potassium permanganate.
