Regeneration-free Manganese Dioxide Filter Material
Short Product Description
Regeneration-free Manganese Dioxide Filter Material is a high MnO₂ content granular media designed for continuous removal of iron, manganese, and hydrogen sulfide in groundwater treatment. With MnO₂ content typically ≥75%, it operates without chemical regeneration, relying on catalytic oxidation. Suitable for municipal and industrial water filtration systems.
