Iron and Manganese Removal – Options and Cautions – WCP …
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+.)
