ADFe

Iron Hydroxide – but not as you know it!

ADFe is an eco-friendly and extremely cost effective alternative to conventional Iron Hydroxide as a way of managing H2S levels in biogas – and it’s produced in the UK!

Fe Nature

A high-performance solid iron additive containing approximately 40% total iron and 30% active iron. Fe Nature provides rapid and reliable reduction of hydrogen sulphide (H₂S) in biogas, helping to protect equipment, reduce corrosion, and maintain efficient plant operation.

Sourced from an innovative environmental restoration process, Fe Nature delivers a sustainable, bioavailable form of iron that supports microbial activity and stable digestion. Supplied in fermentable sacks for direct dosing into the solids feeder, it ensures safe, clean handling with minimal operator exposure.

How to control your H2S levels

High Sulphur in your AD Plant can influence the reactor performance and the biogas quality. Maintaining the right levels of sulphur in your biogas is essential to good CHP operation, and extends the life of for activated carbon filters. Our range of Iron products allow you to react flexibly to your incoming feedstock and maintain optimal conditions for your entire AD system.

Ferric Chloride

A 13% total iron Liquid product. Ferric Chloride is highly reactive and will give the quickest results in reducing H2S in biogas. Supplied in IBCs or delivered into site tank storage, Ferric Chloride is highly corrosive and must be handled with care.
