Iron/Manganese

Worldwide, permanganate oxidation-precipitation of soluble iron or manganese is accepted treatment for groundwater or surface water supplies.  Permanganate, under normal water treatment conditions, rapidly reacts with iron or manganese, producing a precipitated floc that is removed by coagulation, flocculation and settling, or filtration.
