Water Treatment
Potassium Permanganate
KMnO4
Strong oxidizing agent for iron and manganese removal, odor control and chemical processing.
- Chemical name
- Potassium permanganate
- CAS number
- 7722-64-7
Product overview
Potassium permanganate is a dark purple crystalline solid and a powerful oxidizing agent.
In water treatment it is used to oxidize iron, manganese and hydrogen sulfide and to control taste and odor. Industrial uses include chemical synthesis and other oxidation processes. As a strong oxidizer it requires careful storage away from incompatible materials.
