Phosphorus Removal by Alum Addition with a Treatment Goal of 0.02 mg/L; 30 Years of Experience at the Upper Blue Sanitation District
The Upper Blue Sanitation District (UBSD) (formerly known as Breckenridge Sanitation District) was established in 1966 as a Colorado Special District to provide collection and treatment of wastewater to residents of Breckenridge and the upper Blue River watershed. The district has predicted build-out flows to be 25ML/d (6.6 MGD), leading to an annual average phosphorus limit of 0.03 mg/L. To ensure the technological expertise and operational reliability to meet this limit, the district has set a treatment goal of 0.02 mg/L total phosphorus. Multiple technologies are employed at two major facilities, including: Conventional activated sludge followed by tertiary stage Alum flocculation/sedimentation and mixed media filtration, and A/O Bio-P coupled with ballasted Alum flocculation/sedimentation and dynamic sand bed filtration. Additionally one plant wastes sludge into the other, providing a countercurrent dose of Alum. The district began examining molar chemical feed ratios in 2009.
