Manganese Dioxide Filter Media
Iron, Manganese & Arsenic Removal Media
Iron and manganese in groundwater are not just an aesthetic problem staining laundry, fouling equipment, affecting taste. At elevated concentrations they become a health concern, and in industrial systems they cause scaling and corrosion that quietly erode plant efficiency. Manganese dioxide is the treatment answer that’s been proven at every scale, from rural bore water to large municipal groundwater plants.

Why MANGANESE DIOXIDE is trusted by treatment engineers.
Manganese dioxide (MnO₂) is an inorganic oxidation catalyst that removes dissolved iron, manganese, hydrogen sulphide, and arsenic from groundwater. It oxidises dissolved Fe²⁺ and Mn²⁺ to insoluble Fe³⁺ and Mn⁴⁺ forms, which precipitate out and are removed by downstream filtration a mechanism proven across decades of groundwater treatment, not a new chemistry we’re asking you to trust for the first time.
We supply four grades 30%, 50–55%, 70–75%, and 80%+ covering the full spectrum from basic groundwater treatment to demanding arsenic removal applications. Every grade is tested for actual MnO₂ content before dispatch. We do not blend inferior material to hit a price point and label it to a higher grade the number on the bag is the number in the media.
Compatible with both continuous and intermittent regeneration: in continuous systems, potassium permanganate (KMnO₄) is dosed to continuously restore oxidation capacity; in intermittent systems, periodic backwashing with KMnO₄ solution does the same job. Our media is certified for both.

Where is our MANGANESE
DIOXIDE specified.
Specified in systems where oxidation capacity, verified content, and regeneration compatibility define the grade requirement.
Groundwater
Iron & Manganese Removal
Bore, well, and spring water treatment at every scale from community supplies to large municipal groundwater plants.
Odour Control
Hydrogen Sulphide Removal
Oxidises dissolved H₂S to elemental sulphur and sulphate eliminating the rotten-egg odour common in groundwater supplies.
Arsenic Removal
Arsenic Oxidation
High-grade MnO₂ (Grade 3 and 4) oxidises As(III) to As(V) for subsequent adsorption or co-precipitation removal.
Industrial
Industrial Process Water
Iron and manganese removal from raw water feeding boilers, cooling systems, and industrial process equipment.
Regeneration
Continuous Regeneration Systems
KMnO₄ dosed continuously to sustain oxidation capacity without interrupting flow standard for larger installations.
Regeneration
Intermittent Backwash Systems
Periodic backwashing with KMnO₄ solution restores media capacity fits smaller, batch-operated treatment systems.
