Application
<p style="text-align: justify;">
Manganese and Iron Removal from Water</p>
<p style="text-align: justify;">
Manganese dioxide technology is one of the most commonly used and least understood applications for removing iron, manganese, hydrogen sulfide, arsenic and radium.</p>

<div>
Iron and manganese are unaesthetic parameters present mostly in groundwater, causing unwanted precipitation and color.</div>
<div>
Iron removal</div>
<div>
Iron removal is based on the precipitation of dissolved iron (Fe2+) into its oxidized form (Fe3+), as Fe(OH)3 or Fe2O3.</div>
<div>
Iron removal by physical-chemical way consists in iron oxidation by air followed by sand filtration, but other techniques exist as well:</div>
<div>
</div>
<div>
Oxidation + sand filtration</div>
<div>
(physical chemical way)<span style="white-space:pre"> </span>For water with pH > 7, low redox potential, low iron content (< 3mg/L)</div>
<div>
Oxidation + sand filtration + MnO2 filter<span style="white-space:pre"> </span>For higher iron content and/or manganese</div>
<div>
Oxidation + green sand<span style="white-space:pre"> </span>More efficient than sand filtration but required KMnO4 regeneration</div>
<div>
Oxidation + Limestone contactor<span style="white-space:pre"> </span>For acidic water with low redox potential, the limestone contactor increases aggressive water pH by binding </div>
<div>
CO2</div>
<div>
Ion exchange<span style="white-space:pre"> </span>Recommended for continuous process with low iron content. Not pH dependent</div>
<div>
Oxidation can be carried out by various chemicals like chlorine, ozone but is mostly done by compressed air.</div>
<div>
</div>
<div>
Complex bound iron and manganese, e.g. complex bound with humic acids, can be very difficult to remove. In this case oxidation with ozone</div>
<div>
can be a solution.</div>

Manganese removal</div>
<div>
</div>
<div>
For manganese removal only, Manganese dioxide (MnO2) is used as an adsorbent according to the following reaction:</div>
<div>
</div>
<div>
Mn + MnO2 (s) --> 2 MnO (s)</div>
<div>
</div>
<div>
Manganese oxides are then adsorbed on MnO2 grains. When all MnO2 has been consumed, it can be regenerated by sodium hypochlorite.</div>
<div>
</div>
<div>
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 </div>
<div>
come in contact with the manganese dioxide, you get that catalytic reaction and the iron and manganese is filtered out of the water.</div>

Dose
<p style="text-align: justify;">
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. <br />
<br />
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.</p>
