Biological Nutrient Removal (BNR) System for the Shenandoah Wastewater Treatment Facility (WWTF)

The Shenandoah WWTF has a permitted treatment capacity of 2 million gallons per day (MGD) and an average flow of approximately 1.5 MGD. WWTF improvements are currently in the design phase, and construction is anticipated to begin in the first quarter of 2023. Proposed improvements to the facility include improvements to the existing influent pump station, new headworks, new aeration basin, improvements to the existing aeration basin (fine bubble diffusers, mixers, and BNR), new final clarifiers, new RAS/WAS pump station, additional (new) tertiary filters, new UV disinfection, new cascade (post) aeration, conversion of the existing final clarifiers to aerobic digesters, new solids dewatering facilities and a biosolids drying facility. CCWSA is requesting proposals to furnish a new BNR system for the project. The equipment will be preselected by CCWSA but purchased and installed by a contractor as part of the construction contract. This project is a Georgia Environmental Finance Authority (GEFA) Clean Water State Revolving Fund (CWSRF) funded project, and the equipment manufacturer shall meet the requirements identified in the SRF Supplemental General conditions
