Overview

An industrial protein processing facility was experiencing severe organic overloading and solids accumulation in its anaerobic lagoon, resulting in elevated COD and TSS levels, persistent odor complaints, and reduced wastewater treatment performance. Drylet was engaged to restore lagoon performance using a biological treatment program.

‍

The Challenge

• Chronic organic overloading
• Excessive solids accumulation
• Elevated COD, TSS, and ammonia
• Ongoing odor complaints to regulatory agencies
• Risk of costly mechanical dredging

‍

The Drylet Solution

Drylet implemented an emergency response followed by a long-term BioDredger® maintenance dosing program. The treatment approach was paired with operational improvements to reduce upstream loading and support biological recovery within the anaerobic lagoon.

‍

‍

Results

• Significant and sustained reductions in COD and TSS
• Improved lagoon stability and biological activity
• Elimination of surface crusting and lagoon cap
• Restored dischargeable effluent for over one year
• Odor complaints eliminated
• Avoided mechanical dredging and reduced chemical usage

‍

Facility Feedback

“We have been able to operate without dosing chemicals directly into the lagoon. pH has remained stable, biological activity is visible, and we have maintained dischargeable water for over a year.”

‍

Conclusion

This project demonstrates how Drylet’s BioDredger® restores anaerobic lagoon performance, extends lagoon life, and provides a sustainable alternative to mechanical dredging and chemical treatment—while delivering measurable, long-term results.
