What is FerroSorp®?

FerroSorp® is a specialized hydrogen sulfide (H₂S) adsorbent based on iron hydroxide, manufactured in Germany for over 20 years by HeGo BIOTEC and its partners. With proven performance and exceptional efficiency, FerroSorp® has become the preferred solution in the industry for H₂S and odor control, with its global adoption steadily increasing.

Collaboration with Colligo-Tech in Israel

In partnership with HeGo BIOTEC, Colligo-Tech supplies FerroSorp® in Israel, offering comprehensive sales, replacement, and disposal services, tailored to each client’s specific needs.

H₂S Treatment Process Using FerroSorp®

Gases containing hydrogen sulfide (H₂S) pass through a dedicated filter filled with FerroSorp® granules. During gas flow, two main chemical reactions take place:

1. Formation of Iron Sulfide: H₂S reacts with the iron hydroxide in the granules, forming iron sulfide (FeS).
2. Oxidative Regeneration: The oxygen present in the gas stream or air converts the iron sulfide back into iron hydroxide, while elemental sulfur accumulates within the material’s porous structure.

This process enables highly efficient adsorption and allows for the regenerative reuse of FerroSorp®.

Liquid-Phase Applications for H₂S and Sulfide Neutralization

FerroSorp® can also be used as a liquid-phase adsorbent in a variety of applications for H₂S and sulfide neutralization in water and liquid systems:

1. Sulfide and H₂S neutralization at the source inside anaerobic reactors and digesters.
2. Sulfide and H₂S removal in sewer pits, sumps, and pump stations.
3. Sulfide neutralization using a specialized liquid formulation in wastewater conveyance channels and stormwater drainage systems.
