  • The Kinetics of Iron and Manganese Removal - Master

    Dissolved iron and manganese exist as bicarbonate salts, Fe(HCO3)2 and Mn(HCO3)4. The second is the ferric state where the metals have been oxidized and have precipitated out of solution, giving a reddish brown to black coloring of the water.

  • Chlorination‐Filtration for Iron and Manganese

    Processes in which oxidation is followed by removal of suspended solids can effectively remove soluble iron and manganese from water. Three common processes for removing iron and manganese are: (1) aeration‐filtration, (2) chlorination‐filtration, and (3) potassium permanganate‐manganese …

  • Iron (Fe) and water - Water Treatment and Purification

    Other iron compounds may be more water soluble than the examples mentioned above. Iron carbonate has a water solubility of 60 mg/L, iron sulphide of 6 mg/L, and iron vitriol even of 295 g/L. Many iron chelation complexes are water soluble. Usually there is a difference between water soluble Fe 2+ compounds and generally water insoluble Fe 3 ...
