Granulation as the Salvation? Demonstration-scale Testing to Reduce the Cost of IPR

Abstract

The NUA and Garver completed a comprehensive evaluation that assessed various alternatives including Lake augmentation from out-of-basin surface water supplies, groundwater wellfield expansion, stormwater diversion, and others. Ultimately, the evaluation pointed to water reuse as the most feasible solution for the City’s long-term water supply needs. The City then developed a phased plan for the study, piloting, and eventual permitting of a new potable reuse program. The eventual potable reuse program would be constructed to augment the Lake. Multiple trains of enhanced biological nutrient removal (BNR) were operated continuously from June of 2021 to June of 2022. Both the modified University of Cape Town and Aerobic Granular Sludge approaches were tested for capabilities to achieve low total-P and total-N effluents which could meet stringent requirements for IPR in OK.

The Norman Utility Authority (OK), with financial support from the USBR's Title XVI Water Reuse Research Program completed a demonstration and pilot testing program in June of 2022. Design and construction of testing facilities was initiated in the spring of 2021, with support from Garver (design) and Walters-Morgan (construction). The testing facilities included a demonstration-scale batch reactor for aerobic granular sludge treatment of up to 300,000 gpd of raw wastewater influent (screened).

UV Dose Selection, Spot Check Validation, and Full-Scale Performance at a Texas WRF

The Trinity River Authority's Ten Mile Creek Regional Wastewater System (TMCRWS) treats up to 65 MGD of tertiary effluent for Type II water reuse and stream discharge. A project completed in 2021 replaced chlorine disinfection with a new UV disinfection system. An onsite bioassay testing program was utilized for the required performance testing. The testing procedure followed protocols published by the National Water Research Institute in its 2012 UV Disinfection Guidelines, and allowed the
