Preventing air entrainment in water treatment systems
Using CFD to identify and eliminate air entrainment risks before they impact performance
Overview
Air entrainment can lead to serious operational issues in water treatment—from vibrations and thrust loss to broken mixer blades and costly downtime. In this segment, Xylem experts demonstrate how Computational Fluid Dynamics (CFD) helps predict and prevent air entrainment risks before implementation. Using multiphase flow modelling, engineers can assess bubble distribution, evaluate air volume fractions, and optimise mixer and aeration placement—ensuring reliable performance and reduced energy consumption.
