- Upgraded process has consistently exceeded permit requirements for 90% removal of Carbonaceous Biological Oxygen and Suspended Solids.
- Extensive field sampling was performed to characterize influent wastewater characteristics and develop a calibrated BioWin model to optimize performance.
- Process control automation reduced operational costs.
Time and Money Saved
Project was completed 2 years ahead of schedule and the innovative design approach resulted in over $1 billion in overall savings.
