Mang-Ox™
Mang-Ox™ is a high rate, granular filter media used for removing
hydrogen sulfide, iron and manganese compounds from water
supplies. Mang-Ox™ operates both as a classical filter working
with an oxidant and as a catalytic media due to its ability to
accelerate the reaction between the oxidizing agent and any
prevalent dissolved oxygen with sulfide, iron and manganese
present. Dissolved iron, manganese and hydrogen sulfide will stay
in solution unless the equilibrium is changed. Iron and manganese
that is not oxidized become catalytically precipitated and then
adsorbed directly on the media. Mang-Ox™ is a very dense
media that stops oxidized (precipitated) forms of iron, manganese
and hydrogen sulfide from passing through the bed. Most of the
manganous manganese is rapidly removed in the first few inches
of the media where it is further oxidized to manganese dioxide.
The media must be properly back washed to break loose
and remove the filtered contaminants and precipitated iron,
manganese and hydrogen sulfide. System sizing of the control
valve and tank are necessary to sustain media performance.
A continuous reaction occurs with the addition of an oxidant,
regenerating the media surface and replenishing the Mang-Ox™.
For difficult applications, Mang-Ox™ filters can be enhanced
with aeration, chlorination, and ozone. Because of Mang-Ox’s™
naturally high manganese dioxide content, it provides a higher
adsorption capacity than other media. A Mang-Ox™ filter is
recommended before softeners to protect the ion exchange resin
from fouling.
Applications:
• Removal of Iron up to 10 ppm
• Removal of Manganese up to 5 ppm
• Removal of Hydrogen Sulfide (rotten egg smell)
up to 3 ppm
• Not recommended for Iron Bacteria and Manganese bacteria
removal
• Not recommended for tannin and organics removal
Certified to
NSF/ANSI 61
Advantages
• Efficient reduction of manganese, iron & hydrogen sulfide
• Will process high flow rates with low pressure drop
• Ability to be utilized with common oxidants including:
- CL2 (gas), - Sodium hypochlorite,
- Potassium Permanganate
• 10 – 30 second reaction time with oxidant additive
• Converts ferrous iron to ferric iron
• Converts H2S to sulphur
• Converts Manganese to MnO2
• Allows for adequate reaction time to permit for the formation
of ferric hydroxide
• Allows for physical straining of the ferric hydroxide floc and
sulphur until media requires back washing
• Allows for adsorption of MnO
• NSF/ANSI Standard 61-2002 Certified

Mang-Ox (for Sulfide, Iron and Manganese reduction)
Mang-Ox™ operates both as a classical filter working with an oxidant and as a catalytic media due to
its ability to accelerate the reaction between the oxidizing agent and any prevalent dissolved oxygen
with sulfide, iron and manganese present. No regenerates required, backwash only. Will not remove
orange iron, tannins or sulphur bacteria. 60 pound 1/2 cubic foot bag.
