Evaluation of the CLEARGREEN™ SBR Configuration for Sidestream Deammonification Treatment
Client: Henrico County
Hazen and Sawyer, in collaboration with Infilco Degremont, piloted the CLEARGREEN™ sidestream deammonification process at the Henrico County Water Reclamation Facility in Virginia. Deammonification represents an innovative low energy nutrient removal option that can theoretically yield 62.5% oxygen savings and 100% electron donor savings relative to conventional treatment.
Project Outcomes and Benefits
- Study demonstrated that it is possible to enrich anaerobic ammonia oxidizing bacteria from local waste activated sludge (WAS) within 6-9 months.
- Also demonstrated that free ammonia levels and DO control can be used for stable long term control of sidestream deammonification systems.
- Pilot achieved 90% removal of the total inorganic nitrogen from the sidestream load.
