Iron and Manganese Removal

The secondary (aesthetic) MCLs for iron and manganese are 0.3 milligrams per liter (mg/l) and 0.05 mg/l, respectively. Small water plants may choose to either sequestrate or remove iron and manganese. Sequestration only works for combined iron and manganese concentrations up to 1.0 mg/L and only in cases where the treatment is not permanent.

Iron Manganese Removal Industrial Water Treatment ...

Manganese greensand is a common media selection for iron removal. Greensand media contains a relatively low concentration of manganese dioxide, so filter bed regeneration is required. Potassium permanganate is used for greensand regeneration and can be introduced either continuously or intermittently to provide long-term iron manganese treatment.

Iron and Manganese Removal – Options and Cautions – WCP

Aug 15, 2020  The simplest forms of iron are ferrous (Fe2+) and ferric (Fe3+). Iron that is in solution (Fe2+) and remains in solution, is simply removed through ion exchange. Ferrous iron is divalent and will exchange for sodium using cation resin. Ion exchange is also effective in controlling manganous manganese (the divalent form of Mn2+.)
