Anaerobic digestion facilities are central to renewable energy production, but they also generate complex emissions that require robust treatment. From feedstock reception and digestion to biogas upgrading and digestate storage, controlling odours and trace contaminants is essential for compliance and operational efficiency.
hi-flo is designed to provide high-capacity emission control for demanding AD environments. In particular, it delivers effective carbon polishing for anaerobic digestion, ensuring final-stage treatment of air streams before discharge to atmosphere.
As biogas plants operate under fluctuating loads and varying gas compositions, reliable polishing systems are essential to remove residual compounds such as ammonia, hydrogen sulphide and volatile organic compounds. hi-flo provides consistent performance under high airflow conditions, making it well suited to larger municipal and commercial anaerobic digestion sites.
Advanced Carbon Polishing for Anaerobic Digestion
Within anaerobic digestion facilities, emission control often requires a multi-stage approach. While primary treatment systems remove the bulk of contaminants, carbon polishing plays a critical role in capturing residual trace compounds that may otherwise lead to odour complaints or permit exceedances.
hi-flo is engineered to support efficient carbon polishing for anaerobic digestion, treating extracted air from feedstock halls, digesters, gas handling areas and digestate storage tanks. Its high-flow design allows it to handle substantial air volumes while maintaining reliable removal efficiency.
By reducing final-stage emissions, hi-flo helps operators maintain compliance with environmental permits and protect surrounding communities from odour impact.

Reliable Performance Under Variable Loads
Anaerobic digestion plants frequently experience changing operating conditions depending on feedstock composition, seasonal inputs and process adjustments. Emission treatment systems must therefore be robust and adaptable.
hi-flo is built to manage high airflow rates and variable contaminant concentrations, delivering stable polishing performance even during peak operational periods. This makes it ideal for:
- Agricultural digesters
- Food waste AD facilities
- Energy-from-waste plants
- Large-scale municipal digestion sites
For sites requiring integrated biological treatment upstream of polishing systems, Exeon also offers bio-flo. Where multi-stage emission control is needed, scrubX can be incorporated as part of a tailored solution.
Supporting Compliance and Long-Term Efficiency
Effective carbon polishing for anaerobic digestion does more than simply control odour. It helps protect infrastructure from corrosive gases, supports ESG objectives and strengthens community confidence in renewable energy operations.
With hi-flo, operators benefit from:
- High-capacity air treatment for AD facilities
- Reliable removal of residual odorous compounds
- Reduced risk of permit breaches
- Improved site air quality
- Scalable design for future expansion
Its modular configuration enables straightforward installation in both new developments and retrofit upgrades.
