Iron and manganese are unaesthetic parameters present mostly in groundwater, causing unwanted precipitation and color.: Iron removal Iron removal is based on the precipitation of dissolved iron (Fe 2+) into its oxidized form (Fe 3+), as Fe(OH) 3 or Fe 2 O 3.. Iron removal by physical-chemical way consists in iron oxidation by air followed by sand filtration, but other techniques exist as well:

arsenic and manganese to the correct species for removal. Ferric sulfate is added to increase the iron to arsenic ratio (57:1 based on piloting) since the raw water's dissolved iron concentration was found to be variable and too low for coprecipitation. The iron-arsenic floc and oxidized manganese is then removed from the

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+.)

6 Iron and Manganese Removal Handbook levels of manganese in the diet is considered essential for human health. The average daily intake from food is 1–5 mg/day (USEPA 2010). Manganese is detected in approximately 70 percent of groundwater . sites in the United States (WHO 2011), but generally below levels of pub-lic health concern (USEPA 2002).

Other types available are Greensand Iron Filters (which use potassium permanganate powder) and Birm Iron Filters (which work for some applications but do not remove sulfur odors or manganese).

Iron and Manganese Removal Summary Iron and manganese are common in groundwater supplies used by many small water systems. Exceeding the suggested maximum contaminant levels (MCL) usually results in discolored water, laundry, and plumbing fixtures. This, in turn, results in consumer complaints and a general dissatisfaction with the water utility.

Ion exchange may also remove iron and manganese (typically used in home softening). If the water has not been exposed to oxygen, the resins in the softener will remove the iron and manganese ions from the water. If the water contains any dissolved oxygen, the resin can be fouled with iron and manganese …
