    Our high efficiency iron/manganese removal technology  is based on Manganese Dioxide catalytic  conversion  into higher valence insoluble oxy-hydroxides that are then filtered out with an automated backwash filter. The filtrationmedia used for that purpose is DMI-65.

    The DMI-65 is the most sophisticated catalytic 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 arsenic from a water supply given the correct conditions.
