Volumetric Urban Drainage Clarification Optimization with CFD-ML 1: University of Florida; 2: University of Tennessee, Knoxville Urban drainage transports chemical, pathogens, and PM constituents; impacting aqueous chemistry acutely and chronically with consequences to human and ecological health. As a unit operation and process, clarification basins that treat urban drainage, now exceeds 10 million and intercept approximately 25% of the runoff in the USA. Design and regulatory guidance of clarifiers employs presumptive guidance based on mean residence time (RT). Decades of such guidance have led to an impairment designation for most urban clarification basins. A coupled CFD-ML model is presented herein. The databases are generated from CFD simulations for 160,000 combinations of geometric configurations, PM granulometry, partitioning and physical modeling data. Optimized results are based on the CFD-ML model, compared to RT-based models and the CFD-ML results are benchmarked with monitoring data and clarifier retrofit/land costs. Results, benchmarked with monitoring and cost data for full-scale operational clarifiers, demonstrate that optimization provides cost reduction of at least 10X compared to RT requirements at a given level of treatment. | |
