Product Description:
Manganese dioxide (MnO2) is an inorganic compound.In addition to water treatment, MnO2 has many uses, including (but not limited to) the manufacture of batteries, beverage cans, agricultural pesticides and fungicides and electronic circuitry.
Product Application:
Manganese and Iron Removal from Water
Manganese dioxide technology is one of the most commonly used and least understood applications for removing iron, manganese, hydrogen sulfide, arsenic and radium.
RXSOL Manganese Dioxide
Iron and manganese are unaesthetic parameters present mostly in groundwater, causing unwanted precipitation and color.
Iron removal
Iron removal is based on the precipitation of dissolved iron (Fe2+) into its oxidized form (Fe3+), as Fe(OH)3 or Fe2O3.
Iron removal by physical-chemical way consists in iron oxidation by air followed by sand filtration, but other techniques exist as well:
Oxidation + sand filtration
(physical chemical way) For water with pH > 7, low redox potential, low iron content (< 3mg/L)
Oxidation + sand filtration + MnO2 filter For higher iron content and/or manganese
Oxidation + green sand More efficient than sand filtration but required KMnO4 regeneration
Oxidation + Limestone contactor For acidic water with low redox potential, the limestone contactor increases aggressive water pH by binding
CO2
Ion exchange Recommended for continuous process with low iron content. Not pH dependent
Oxidation can be carried out by various chemicals like chlorine, ozone but is mostly done by compressed air.
Complex bound iron and manganese, e.g. complex bound with humic acids, can be very difficult to remove. In this case oxidation with ozone
can be a solution.
Manganese removal
For manganese removal only, Manganese dioxide (MnO2) is used as an adsorbent according to the following reaction:
Mn + MnO2 (s) --> 2 MnO (s)
Manganese oxides are then adsorbed on MnO2 grains. When all MnO2 has been consumed, it can be regenerated by sodium hypochlorite.
Manganese dioxide is a catalyst. So when there is a tiny bit of dissolved oxygen in the water, and the iron and manganese in the water
come in contact with the manganese dioxide, you get that catalytic reaction and the iron and manganese is filtered out of the water.

Product Procedure:
Manganese dioxide is well known as a catalyst for selective oxidation of organic compounds; it is also a known catalyst for oxidation of CO to CO2 at low temperatures.
Manganese dioxide catalyzes the decomposition of hydrogen peroxide to oxygen and water. Since manganese dioxide is a catalyst, it is not consumed in the reaction.
