This product is no longer manufactured, it is replaced by this media which does not require regeneration. We will no longer carry it once our supplier is sold out, contact us for details. 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.

How Manganese Greensand Media works:

Soluble iron and manganese are oxidized 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 back washing.


When oxidizing capacity of manganese greensand media is exhausted, the bed has to be regenerated with a weak potassium permanganate solution (KMnO4) , thus restoring the oxidizing capacity of the media. 1 1/2 to 2 ounces of potassium permanganate, 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.
