Can Hydrogen Peroxide Be Used to Remove Manganese and Iron from Well Water?


Can Hydrogen Peroxide Be Used to Remove Manganese and Iron from Well Water?

Richard


Hello Richard,

Thanks for contacting us regarding your well water.

See this link here, a graduate paper, but seems to be a thorough study of manganese removal methods:


http://d-scholarship.pitt.edu/9490/1/Weakley_Thesis_2009.pdf

In it, the study found “Hydrogen Peroxide at these pH levels did not prove to be an adequate oxidizing agent for manganese. Iron however was oxidized when hydrogen peroxide was
present ... In conclusion, there was no benefit to using hydrogen peroxide, it did not oxidize the manganese and it created massive complications with chlorine used for disinfection.”




One point interesting about the chart above, is that it takes over 100 minutes with only chlorine to perfectly oxidize manganese. But if chlorine combined with our Pro-OX manganese dioxide media iron filters (left), or Greensand iron filters, the manganese is effectively removed by a catalytic reaction between the filter media and the chlorine, which results in manganese getting instantly oxidized on the surface of the filter media.

A strong backwash (10 GPM is OK) is needed to flush out the accumulated manganese oxides.

If you are still interested in a hydrogen peroxide treatment system, see this page for links to the peristaltic pump (right) and filters:

Here is the link to the Pro-Ox iron filter product that works well with chlorine feed for manganese removal:
