When the Boaz Water & Sewer Board faced new, lower phosphorus limits under the Slab Creek Water Reclamation Facility (WRF) NPDES permit, they needed a reliable and efficient solution that would meet strict environmental standards while maintaining operational flexibility.
To achieve this, The TDH Company partnered with Krebs Engineering, the project engineer, to evaluate treatment options and identify the most effective technology for long-term compliance and performance.
After careful evaluation, the Sanitaire Casperon Process was selected for its proven performance, energy efficiency, and ease of operation. This advanced process is specifically designed to support biological nutrient removal while giving operators the flexibility to adjust for changing flow and loading conditions.
The 4.88 MGD plant upgrade encompassed a full suite of improvements, including new headworks, a redesigned biological process, clarifiers, and digesters, representing a major investment in sustainable infrastructure for the Boaz community.
This project was made possible through collaboration among multiple trusted manufacturers and engineering experts. TDH worked closely with each partner to ensure seamless integration of all equipment and systems:
Each of these technologies played a crucial role in supporting the overall process efficiency, reliability, and compliance of the upgraded facility.
Through teamwork, technical expertise, and strong manufacturer partnerships, the upgraded Slab Creek WRF is now fully meeting all phosphorus discharge requirements. Beyond regulatory compliance, the project represents a shared commitment to environmental stewardship and water quality for the Boaz community and surrounding region.
