Evaluation of the CLEARGREEN SBR Configuration for Sidestream Deammonification Treatment

Evaluation of the CLEARGREENTM SBR Configuration for Sidestream Deammonification Treatment Client: Henrico County Location: Virginia Hazen and Sawyer, in collaboration with Inlco Degremont, piloted the CLEARGREENTM sidestream deammonication process at the Henrico County Water Reclamation Facility in Virginia. Deammonication 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 deammo
