In addition to its catalytic property, high grade MNO2 possesses specific properties that ensure the highest efficiency of the oxidizing agent used, such as potassium permanganate, chlorine, or dissolved oxygen. This leads in a faster response rate and full oxidation. These characteristics, together with its exceptional filtration efficiency, ensure that the High grade MNO2 can exchange electrons in the same way as ion exchange resin can exchange ions.

Thus, iron and manganese can be oxidized as long as the following elements are available:
Oxidation/Reduction
Electrons are still present. The electrons can be replenished either intermittently by adding an oxidizing agent such as chlorine or continuously by dosing the oxidizing agent.
Catalysis
The catalytic action guarantees that the oxidizing agent, which can be potassium permanganate, chlorine, or dissolved oxygen, is used to its full potential.
Filtration
A high contact area and good filtering qualities are obtained due to the nodular form and size distribution.

Applications of Manganese Dioxide Mno2
Iron, manganese, and hydrogen sulfide are all successfully removed from natural waters by high grade MNO2. Water for industrial and home usage must be iron and manganese free in large quantities. Water for municipal usage must not have iron or manganese quantities larger than 0.2 and 0.05 ppm, respectively, and preferably less than 0.05 and 0.02 ppm. It is nearly impossible to operate with iron or manganese carrying fluids in certain industries, such as pulp and paper mills, tanneries, textile plants, dye houses, and laundries, because they would produce unpleasant stains, streaks, spots, and off-colors on many manufactured items. Iron and manganese clog ion exchange resins as well. As a result, in most ion exchange procedures, a pretreatment stage is required.
High-quality MNO2 is especially effective. Because of its catalytic capabilities, it is used in conjunction with chlorine dosing to reduce iron and manganese in water supplies to the previously indicated extremely low levels. Alternative techniques such as aeration, chlorination, and filtering cannot produce effluent of the same quality as High grade MNO2.
