FM-IGS-01 Manganese Greensand Media, Water Treatment IGS 1 cu.ft.

Manganese Greensand media CQ-IGS is formulated from a glauconite green sand which is capable of reducing iron, manganese and hydrogen sulfide from water through oxidation and filtration. Soluble iron and manganese are oxidised and precipitated by contact with higher oxides of manganese on the green sand granules. The hydrogen sulfide is reduced by oxidation to an insoluble sulfur precipitate. Precipitates are then filtered and removed by backwashing. Manganese Greensand Media specifications: When oxidising capacity of manganese greensand media is exhausted, the bed has to be regenerated with a weak potassium permanganate solution (KMnO4) , thus restoring the oxidising capacity of the media. 1 1/2 to 2 ounces of potassium permanganante, in solution, per cubic foot of greensand media is considered sufficient for normal regeneration. It is required to vigorously backwash and regenerate the bed when it is placed in service and before its oxidation capacity is completely exhausted. Operating the bed after oxidation capacity has been exhausted will reduce its service life and may cause staining. Type: Manganese Greensand Quantity: 1 cu.ft. Weight: 85 lb. per cubic foot
