Manganese Greensand - Riversands

Manganese Greensand is used to remove iron, manganese and hydrogen sulphide from water resources. It is processed from the mineral glauconite (commonly referred to as zeolites). Using iron exchange properties of this natural zeolite, a manganese dioxide coating is deposited on the surface of the glauconite grains. The manganese dioxide acts as a vehicle in the oxidation reduction reaction of ...

If chlorine and/or KMnO4 are used for pre-filter oxidation of iron, the run time can be extended for higher iron levels with the addition of an anthracite layer on top of the greensand media. A primary concern is to not trap too much ferric hydroxide within the greensand because you can have precipitated iron coming through and a much greater pressure will be needed for adequate back flushing ...
