Permanganate is a strong, versatile oxidizing agent that contains the permanganate ion (MnO₄⁻). Carus manufactures both potassium permanganate and sodium permanganate, each offering powerful oxidation capabilities for various applications.
Potassium permanganate is commonly used in municipal drinking water treatment, soil and groundwater remediation, and organic oxidation.
Sodium permanganate provides similar oxidizing strength but is often preferred for liquid applications due to its high solubility, making it ideal for industrial processes and in-situ chemical oxidation (ISCO) for remediation.
Both products are used in:
- Municipal & industrial water treatment
- Mining wastewater treatment
- Surface polishing in electronics
- Odor control in food and beverage industries
At Carus, we provide innovative environmental solutions that help our customers meet compliance and protect natural resources, contributing to a cleaner, safer world.
