Computational Fluid Dynamics (CFD) modeling of secondary clarifiers is used to understand and predict the treatment capacity. This session will overview the process including field sampling and modeling results and include a case study at Eastern Municipal Water District that demonstrates how results can be applied for facility planning.

Learning Objectives:

Discuss benefits of clarifier CFD modeling for evaluation of upgrades.
Understand the field sampling procedures and how they are used to calibrate the CFD model.
Apply CFD modeling to optimize clarifier design and understand capacity limitations.
Leverage modeling results to assist improving secondary clarifier operation
