Product Overview
Potassium Permanganate is a powerful inorganic oxidising agent used extensively in water treatment, wastewater treatment, environmental remediation, chemical processing and specialised industrial applications.
When dissolved in water it produces an intense purple solution and provides strong oxidation capability for various contaminants and reduced chemical species.

Applications
- Drinking-water treatment
- Wastewater treatment
- Iron and manganese oxidation
- Odour-control applications
- Industrial water treatment
- Environmental remediation
- Chemical oxidation
- Process-water treatment
- Laboratory oxidation reactions
Water-Treatment Benefits
Potassium Permanganate is used as an oxidising chemical in treatment systems where controlled oxidation of contaminants is required.
The required dose should be determined according to water chemistry and treatment objectives rather than applying a universal dosing rate.
Key Benefits
- Powerful oxidising agent
- Solid product for convenient storage
- Effective water-treatment chemistry
- Broad industrial oxidation capability
- Highly recognisable endpoint colour in some controlled analytical applications
Storage & Safety
Strong oxidiser.
Keep dry and segregated from combustible materials, organic chemicals, reducing agents and incompatible substances.
Prevent uncontrolled environmental release.
