The DMI-65 is a similar filtration media to Manganese Greensand, however theDMI-65 does not need to be re-generated with potassium permanganate at all. DMI-65 is a revolutionary Infusion Technology catalytic filtration media designed for the removal of iron and manganese without the use of potassium permanganate. The unique micro-porous structure of DMI-65 efficiently removes dissolved iron to as low as 0.001 ppm and manganese to 0.001 ppm. The DMI-65 acts as an oxidation catalyst with immediate oxidation and filtration of the insoluble precipitates. The media has been used extensively in a wide variety of applications for over 30 years. The DMI-65 is a water filtration media that has extremely high capabilities of removing both Iron (Fe) and Manganese (Mn) simultaneously through low cost catalytic oxidation and retention of precipitate. The DMI-65 will also remove all arsenic from a water supply.The DMI-65 is one of the few water filtration media’s in the world developed to remove Iron, manganese and arsenic that is certified to NSF/ANSI 61 for drinking water applications.
