H₂S Reduction through O2 Injection

A simple, cost-effective solution for significant improvements in your Biogas operation.

Why Choose O₂ Injection?

Hydrogen sulfide (H₂S) is a major challenge in wastewater, biogas, and industrial systems, causing corrosion, odor complaints, and safety risks. Oxygen injection offers a proven, low-maintenance way to eliminate these issues.

Why Choose EFI USA?

EFI is the industry leader in turnkey Oxygen (O2) and Air Injection technology. Our technologies can achieve up to 90% reduction of H2S levels in the digester, reducing the need for treatment of the biogas for air permit compliance, RNG production, and CO2 system inlet specs.

Operational Improvements with O2 Injection

Improvement of Air Quality: Allowance for less stringent air permit requirements, ease of permit approval, and compliance with air regulatory limits.

Enhanced Biogas Quality: Ability to significantly reduce H2S in the raw biogas (60 – 90%) allowing for extended lifespan of the media by “EFI USA”

Safety Improvement: Major improvement in worker safety by reducing the risk of H2S exposure

Corrosion Control: Reduction of overall operating costs associated with H2S removal by optimizing media performance and minimizing the need for media replacement, lower maintenance expenses, less downtime and less waste generation.

 Cost effective: Most systems see ROI within months due to reduced corrosion and chemical spend
