Sulfide Control and Supplemental Dissolved Oxygen for Dairy Production Facilities

The Challenge

A large dairy production company faced persistent sulfide-related odor issues in their wastewater treatment plant outfall at two separate facilities. In addition, one facility struggled to maintain target dissolved oxygen (DO) levels in its Bio Tower, impacting biological treatment performance. The company needed a rapid, effective solution to control odors, stabilize treatment processes, and ensure compliant and efficient operations at each facility.

USP Technologies’ Solution

USP Technologies responded quickly with a hydrogen peroxide treatment program tailored to each facility’s needs. This program included:

• Rapid mobilization: USP quickly delivered hydrogen peroxide and installed dosing systems at both sites
• Targeted dosing and monitoring: Strategically placed injection points allowed USP Technologies to deliver:
  • Reduced H2S levels at each location
  • Supplemental DO in the Bio Tower at the second facility, improving biological treatment efficiency

Results at a Glance

With rapid deployment of USP Technologies’ full-service hydrogen peroxide treatment program, the organization achieved:

• Effective Odor Control: The program resulted in a dramatic reduction of sulfide-related odors at both facilities
• Process Optimization: Stabilizing DO levels in the Bio Tower enhanced overall wastewater treatment performance
• Sustained Success: After the systems had been in place for a year with continued success, USP Technologies began transitioning the program to deliver more permanent hydrogen peroxide storage, dosing, and monitoring systems for long-term support
