• Manganese Greensand is formulated from a glauconite greensand which is capable of removing iron, manganese, and hydrogen sulfide from water through oxidation and filtration.
• Manganese and soluble iron are oxidized and precipitated by contact with higher oxides of manganese on the greensand granules. The hydrogen sulfide is eliminated by oxidation to sulfate and an insoluble precipitate. Precipitates are then filtered and removed by backwashing.
• When the oxidizing capacity power of the Manganese Greensand bed is exhausted, the bed has to be regenerated with a weak potassium permanganate (KMnO4) solution thus restoring the oxidizing capacity of the bed. Two to four ounces of potassium permanganate, in solution, per/cu.ft. of Manganese Greensand is considered sufficient for normal regeneration.

Capacity/Cu.Ft.:

• Iron Alone-550 gr. (10,000 gal. of water containing 1 ppm iron/cu.ft.)
• Iron and Manganese - 400 gr. (7,000 gal. of water containing 1/2 ppm iron and 1/2 ppm manganese/cu.ft.)
• Hydrogen Sulfide - 175 gr. (3,000 gal. of water containing 1 ppm hydrogen sulfide. cu.ft.
