H2S and Sulfide Control for a Poultry Processing Facility

The Challenge

A large poultry processing facility was experiencing high levels of hydrogen sulfide (H2S) and liquid sulfides downstream of its anaerobic digesters. These conditions created:

• Safety concerns for operators due to H2S exposure risk
• Excessive sulfide toxicity impacting the biological wastewater treatment process

The facility needed a reliable solution to mitigate sulfide issues, protect worker safety, and maintain treatment performance to target levels.

USP Technologies’ Solution

USP Technologies delivered a full-service hydrogen peroxide treatment program designed to address process performance challenges. Our solution included:

• 7,800 gallon hydrogen peroxide storage tank
• Dual-pump dosing skid for precise chemical delivery
• Over 300 feet of injection piping to two critical dosing points where we delivered:
  • Post-anaerobic DAF unit: Reduced H2S and liquid sulfide levels, improving DAF efficiency
  • Biological wastewater treatment process: Provided supplemental dissolved oxygen (DO) on demand to optimize performance and enhance ammonia removal

Results at a Glance

USP’s turn-key program reduced H2s and liquid sulfide levels, improved the facility’s dissolved air flotation (DAF) system performance, and optimized biological treatment to help improve efficiency and effectiveness at the facility.
