Join Metro Water Recovery at their Hite Facility for a technical luncheon focusing on the optimization of phosphorus recovery, impacts on dewatering and biosolids and startup of the new Biosolids Dewatering and Storage Facility (BDSF). Metro’s phosphorus recovery system began operating in 2020 and has successfully maintained consistent soluble phosphorous transformation >90%. However, additional optimization efforts were required to maximize struvite separation, determine online instrumentation, and minimize alkalinity loss. Following these optimizations, Metro’s Technology and Innovation Department conducted in-depth evaluations of cost and chemical usage, which revealed new opportunities for optimizing polymer and dewatering processes and allowing for more efficient operational practices. The presentation will discuss ongoing polymer optimization concepts and data, including standardized centrifuge testing, and how these efforts contribute to improved solids handling. Additionally, broader objectives of enhancing performance across biosolids handling and hauling processes will be addressed, drawing insights from past initiatives and reporting.
