Description : Manganese Greensand is formulated from a glauconite greensand which is capable of reducing iron, manganese and hydrogen sulfide from water through oxidation and filtration. Soluble iron and manganese are oxidized and precipitated by contact with higher oxides of manganese on the greensand granules. The hydrogen sulfide is reduced by oxidation to an insoluble sulfur 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. one and a half parts to two ounces of potassium permanganate, in solution, per cubic foot of Manganese Greensand 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 totally exhausted. Operating the bed after oxidation capacity is exhausted will reduce its service life and may cause staining. Features : Iron reduction over wide pH range - Effective reduction of hydrogen sulfide In addition to iron and/or manganese No Activation needed Low attrition for long bed life What does it do: Remove Iron, Manganese, and hydrogen sulfide from water. Good to know: It is used for General Potable / Drinking water treatment, Municipal water treatment, Waste water treatment, Water re-use applications, Ground water treatment, Aquaculture systems, Agricultural water treatment.
