A comprehensive evaluation was performed to determine the most suitable treatment technologies and approach for plant improvements as part of recommissioning the KWRF, including the previous membrane bioreactor (MBR) process and other possible processes based on current developments in wastewater treatment and reclamation. A total of 35 different technologies were considered for this project. An initial screening of the technologies based on their applicability to the KWRF’s current needs and technology maturity was performed to narrow the options down to 5 applicable treatment processes. This detailed evaluation included wastewater characterization, evaluating the salvageability of the existing equipment/infrastructure, identification, screening, and modeling alternative treatment technologies to be employed in the re-started KWRF. The alternatives were comparatively assessed based on process performance, social, environmental, and economic impacts. This included treatment and financial impacts of different phasing, infrastructure components, and process improvements at the plant, as well as incorporating supporting information, energy analysis, capital and operating cost opinions. An updated MBR, incorporating current technology, was selected as the City’s preferred process for the restarted plant process. The capital cost was the lowest since most of the existing facility can be reused and the superior water quality will extend the life of the ASR wells and reduce the back pumping requirements for well maintenance. The MBR process also offers the greatest potential treatment capacity attainable at the Kyrene WRF site.
