Description DMI-65 Catalytic Media | 21Kg High-Performance Iron & Manganese Removal Advanced Australian Technology for Ultra-Low Contaminant Levels (0.001 PPM) DMI-65 is a revolutionary, silica sand-based catalytic filtration medium engineered in Australia. It represents the ultimate solution for Iron and Manganese removal, achieving near-undetectable levels as low as 0.001 PPM. Unlike traditional Greensand, DMI-65 acts as an immediate oxidation catalyst that does not require Potassium Permanganate (KMnO_4) for regeneration. Its unique microporous structure effectively removes Arsenic, Aluminum, and other heavy metals, making it the preferred choice for high-demand borehole and municipal water treatment. Features Ultra-Premium Removal: Efficiently reduces dissolved Iron and Manganese to industry-leading levels of 0.001 PPM. Safer Regeneration ($KMnO_4$-Free): Eliminates the need for hazardous Potassium Permanganate, using only low-dose Sodium Hypochlorite (Chlorine) for activation. Multi-Contaminant Capability: Capable of reducing Ammonia and various heavy metals, including Arsenic and Aluminum. Instantaneous Oxidation: Operates as a powerful catalyst for immediate oxidation, allowing for superior filtration speeds and smaller vessel footprints. Stain Prevention: Completely prevents the orange/brown (Iron) and black (Manganese) staining typical of untreated groundwater. Long Operational Life: Features a robust physical structure with a low attrition rate for extended service years. How It Works Catalytic Oxidation: The media surface accelerates the reaction between dissolved oxygen and dissolved metals, converting them into insoluble precipitates. Physical Filtration: These oxidized particles are then trapped within the media bed and easily removed during a standard backwash cycle. The Result: Crystal clear, high-purity water without the chemical complexities and safety risks of traditional iron removal methods.

Replacement Cycle: DMI-65 has an exceptionally long lifespan; replace the media every 3 – 5 years depending on water quality and volume processed. Regular Backwashing: Perform routine backwashes to clear trapped precipitates and prevent media fouling.
