Iron Removal Plant is a process that requires limited pressure drop so that filters can reduce pressure drop with a minimum amount of pressure drop. In most Iron Removal Filter, the iron is oxidized during the process of converting it from a ferrous state (dissolved or soluble) to a ferric state (undissolved).

How is iron removed from groundwater?
Iron is generally removed from groundwater by the process of aeration or chemical oxidation followed by rapid sand filtration.

When water passes through the bed, the media attracts soluble ferrous iron and converts it to an insoluble state. That allows a filter to capture the iron precipitate, leaving the water iron-free.
