Manganese Dioxide Filter Media – GLOBAL FERRONIL
The GLOBAL FERRONIL range of Manganese Dioxide (MnO₂) offers a proven solution to remove iron, manganese, and hydrogen sulphide from water, especially groundwater. Its catalytic action converts soluble ferrous (Fe²⁺) and manganous (Mn²⁺) salts to insoluble forms, enabling efficient filtration without frequent chemical regeneration.
Why Choose GLOBAL FERRONIL Manganese Dioxide

Applications of Manganese Dioxide
Municipal and industrial water treatment
Removal of iron, manganese to meet potable water standards.
Groundwater filtration
Efficiently eliminates iron/manganese without adding chemicals.
Hydrogen sulphide control
Also acts on H₂S for odour removal and improved taste.
Advantages of Manganese Dioxide Over Other Filter Media
No hazardous regeneration
unlike manganese greensand which needs potassium permanganate replacements.
Lower chemical operating costs
catalytic action eliminates the need for frequent oxidant dosing.
Consistency & ease of use
simple maintenance and backwash-based cleansing reduces downtime and overall cost of using a product or system throughout its entire lifecycle.
