This is a powdered substance based on iron(III) oxide-hydroxide FeO(OH) and is used to bind hydrogen sulfide inside anaerobic digesters. It provides a cost-effective, non corrosive alternative for reducing H2S levels in biogas produced by digesters. For more information on the noncorrosive characteristics of this powder, please contact our sales group for a copy of our Corrosiveness Study.

Application

The powder should be evenly distributed within the digester and concentrations should be maintained at a constant level. It can be added in its dry form or in a suspension ratio of 2:1 water and powder, by volume.

The ferrous sulfide formed by the process is an almost insoluble compound.
