Iron and manganese removal

Nomado builds units that remove iron and manganese from water.
Our plug & play offer
Commissioning made easy and maintenance taken into account from the design phase.

Containerized solutions

Suitable for the most extreme conditions, this is a first-class solution for a robust, lasting and economical unit.

SKID solutions

Compact, easily transportable and self-sufficient unit, the Skid is compatible with all drinking water production technologies.

The solutions that we offer adjust extremely well to variations in the quality of the water to be treated and the quantity of the load that it contains. Our treatment units are integrated into sea containers or mounted on SKIDs thereby reducing production times, installation times on site and civil engineering costs.
Sheet metal work and welding of the hydraulic structures are performed directly inside the container. Waterproofing is ensured by a seal made of special coatings that constitutes a perfectly monolithic block. It prevents water from coming into contact with the structures. The Coatings’ properties are always chosen in accordance with the project’s specifics (Health compliance certificate, WRAS, aggressiveness of reagents or water, etc.).


Whether in France or internationally, our water treatment experts are available to help you define the treatment unit that will best suits your needs.

Understanding how iron and manganese removal works


To remove excess iron and/or manganese contained in water, we most often use oxidation followed by catalysis and filter retention. Biological iron or manganese removal may also be implemented when dealing with permanent facilities where effluent characteristics vary little.

Oxidation may be carried out in two different manners :

  • Using chlorine or potassium permanganate
  • Using air

We mainly perform chlorine oxidation because it is easy to adjust to the variations in iron and manganese concentration levels and the reagent is readily available throughout the world.
However, we may opt for oxidation with air if reagents are difficult to source (i.e. remote job sites supplied by air or other reagents such as potassium permanganate, if the project requires.


Iron and manganese oxidation is boosted by using a filtering media that catalyzes the reaction. This media can be blended with the sand inside the filter. This catalytic process is based on the absorption then oxidation of the manganese or iron followed by precipitation on the surface of the filtering media. The media thereby plays the role of an ion exchanger and absorbent. Generally, it is a manganese oxide.
