Water can contain Iron (Fe), Manganese (Mn), and Hydrogen Sulfide (H2S). Soluble iron and manganese are oxidized and precipitated by contact with higher oxides of manganese on the proprietary blend of oxidation media. Hydrogen Sulfide is oxidized into an insoluble sulfur precipitate. Precipitates are filtered, retained, and then removed by vigorous back-washing. When the oxidizing capacity of the media is exhausted, the system has to be regenerated and sparged with ambient air, which makes it envirnmentally friendly.
