Sodium Permanganate

Sodium Permanganate (NaMnO₄) is a powerful oxidizing agent supplied as an aqueous solution. It offers significantly higher water solubility compared to Potassium Permanganate, making it advantageous for applications where rapid dissolution and high dosing concentrations are required. We supply two concentration grades: 20% (SP ORG 20) and 40% (SP ORG 40).

Applications

Sodium Permanganate's high solubility and liquid form give it specific advantages for continuous dosing systems and applications requiring precise control.

Municipal drinking water treatment
Iron and manganese removal from groundwater
Taste and odor control in water supply
Wastewater treatment and effluent polishing
Industrial process water treatment
Natural gas purification (H₂S removal)
Landfill gas treatment
Biogas upgrading and purification
Textile and dye processing
Chemical intermediate in organic synthesis

Sodium vs. Potassium Permanganate

Buyers often ask why to choose Sodium Permanganate over Potassium Permanganate. Key differences:

Higher solubility — NaMnO₄ is ~20x more soluble than KMnO₄ in water
Liquid form — easier to handle, meter, and inject in continuous systems
No dissolution step — ready to use as supplied, no mixing required
Gas purification advantage — preferred in scrubber systems for H₂S removal
Lower residual — treated water achieves clear results with appropriate dosing
No sodium advantage for KMnO₄ — preferred where sodium loading is restricted

Storage: Store in a cool, well-ventilated area in tightly closed containers. Avoid contact with combustible materials. Refer to SDS for full handling instructions.
