Permanganate Injection

Permanganates have proven to be useful primarily for the oxidation of chlorinated ethenes such as TCE, and PCE. Remington has completed injections of both sodium and potassium permanganate at multiple sites throughout the country. While chemically similar, Sodium Permanganate and Potassium Permanganate differ in physical properties. Potassium Permanganate is a crystalline solid, usually shipped in pails, with a maximum solubility of 6% in 20°C water. Sodium Permanganate is a liquid, usually shipped as an aqueous solution having a concentration of 40%+. As a liquid product, sodium permanganate requires a simple dilution prior to injection. Because it can be applied at higher concentrations, it is often used at sites with tight geology (clay, silts, etc.) where large volumes of liquid cannot be injected.

Permanganates has been successfully applied in situ at thousands of sites in the United States, Canada, South America, Europe and Japan for treatment of various contaminants of concern found in soil and groundwater. The oxidation process occurs rapidly with no hazardous byproducts. Permanganates are stable compounds that do not require activation (pH adjustment, heat, iron, etc.) prior to injection. Potassium Permanganate is much cheaper by weight than Sodium Permanganate.
