Iron Hydroxide Powder

S+A Blackwell is the exclusive UK agent for FerroBio, who mine and then process high quality Iron Hydroxide powders for biogas desulphurisation applications.

FerroBio is a natural Iron compound, made of functional oxides & hydroxides, that is used for Hydrogen Sulphide (H2S) control in biogas plants. Upon reaction with Hydrogen Sulphide, the FerroBio generates Iron Sulphide & pure Sulphur which, in turn, are used as additives to enhance the properties of fertilisers.

FerroBio is easy to use, non-toxic, not hazardous or corrosive and it helps generate high-quality compost that enhances all types of fertilisers.

FerroBio is 100% natural, comes straight from the mine and contains naturally occurring trace-elements of Cobalt (Co), Copper (Cu), Manganese (Mn), Molybdenum (Mo), Nickel (Ni), Potassium (K), Selenium (Se) & Zinc (Zn), which all have a positive impact on the biology of the digestate in the biogas plant. In some cases, these included trace-elements will allow plant operators to reduce (or even remove) their investment in additional trace-elements, making FerroBio an extremely efficient & economical choice for your plant.

We have two grades of product which are standard FerroBio and also our fast-acting FerroBio+.

Material is held in UK stock and shipped in biodegradable 20kg bags or in 1-ton big bags.
