An in-depth look into iron and manganese treatment | Water ...

To address this, manganese (II) can be oxidized to insoluble manganic dioxide (MnO 2) and removed subsequently by a clarification or filtration process. Oxidation to this more insoluble form can be achieved by a combination of the right water quality conditions using aeration, chlorine, chlorine dioxide, permanganate or others.

The reduction and oxidation behaviour of manganese oxides ...

The reduction of manganese oxides with methane was studied to investigate the suitability of manganese as an oxygen storage compound. Manganese oxides are reduced by CH 4 to a lower-valent manganese oxide, producing CO 2 and water. Once the manganese oxide is reduced, it can be regenerated, i.e. reoxidised.
