Ferric Sodium Citrate for Biogas Production

The aqueous solution Lohtragon^® C08 based on Ferric Sodium Citrate demonstrates superior efficacy in quickly reacting with and neutralizing H₂S compared to solid alternatives. In addition to its targeted action against hydrogen sulfide, Lohtragon^® C08 also functions as an effective acid scavenger, helping to stabilize the system by neutralizing acidic byproducts. This results in reduced odor complaints and mitigated corrosion within the facility. Additionally, the ease of dosage control and handling made the process more manageable and efficient, establishing the solution as a preferable choice for H₂S elimination.

Key benefits of Iron(III) Sodium Citrate, Solution in Biogas Production:

Effective H₂S neutralization: Rapid and reliable reaction with hydrogen sulfide reduces odors and improves air quality
System stabilization and corrosion protection: Dual function as an acid scavenger helps neutralize acidic byproducts, reducing corrosion and extending equipment lifespan.
Easy handling and dosing: Liquid form allows for simple, precise application, improving operational efficiency and process control.
