Background
Fayetteville, Arkansas, often ranked among the best places to live in the U.S. is known for its commitment to sustainability and environmental leadership. To further enhance its water quality and meet future regulatory demands, the City initiated a disinfection system upgrade at the Paul R. Noland Wastewater Treatment Facility. This project would reflect the City’s forward-thinking approach to clean water and community health.
The Challenge
To modernize its disinfection capabilities, Fayetteville required a system that could:
- Deliver high-efficiency pathogen reduction with minimal chemical use
- Remove contaminants of emerging concern (CECs) such as pharmaceuticals and endocrine disruptors
- Support variable flow conditions with consistent treatment performance
- Reduce energy consumption and operational cost compared to legacy UV and conventional ozone systems
- Seamlessly integrate with existing plant infrastructure and operations
The new system also needed to reflect the City’s ongoing environmental goals by incorporating sustainable and energy-efficient technology.
The Approach
The City partnered with BlueInGreen, LLC, a Fayetteville-based technology company specializing in gas dissolution systems, to design and implement a next-generation ozone disinfection system. Working in collaboration with Pinnacle Ozone Solutions and PCI Gases, the team delivered a highly compact, efficient, and cost-effective solution.
At the heart of the system is a powerful combination of:
- Pinnacle’s Zenith™ ozone generator platform, known for energy efficiency, reliability, and modular scalability
- PCI’s DOCS-500 on-site oxygen generation system to ensure consistent ozone production
- BlueInGreen’s patented HyDOZ™ injection system for industry-leading mass transfer performance and ozone utilization
Pinnacle’s Solution
Pinnacle Ozone Solutions supplied the complete Zenith™ ozone generation system, featuring:
- QuadBlock® modular technology for efficient, low-maintenance operation
- Turnkey integration with oxygen feed, injection, and destruction systems
- Up to 40% lower energy and operating cost than conventional ozone systems
- A small system footprint, perfect for retrofitting within the existing facility layout
- Minimal operator interface, fully automated process controls, and real-time performance monitoring
Pinnacle also worked closely with BlueInGreen and PCI to ensure seamless integration and commissioning of the full system.
The Results
Upon implementation, the City of Fayetteville achieved:
- >99% disinfection efficiency across variable flows
- Significant reduction in emerging contaminants, including trace pharmaceuticals and endocrine disruptors
- 40%+ reduction in energy and O&M costs versus traditional disinfection technologies
- Improved sustainability, supporting Fayetteville’s environmental goals
- A high-performance, low-maintenance system ready to support future regulatory needs
This collaborative installation now serves as a model for municipalities nationwide aiming to upgrade aging infrastructure with cutting-edge, energy-efficient technology.
