The existence of increasingly powerful computers at an affordable price has led to the extended use of Computational Fluid Dynamics (CFD), initially developed for the aeronautics sector. The study presented here illustrates the use of a calculation code that is readily available in the retail sector. FLUENT is used to evaluate the hydraulic efficiency of chlorination tanks. The aim is to provide a homogeneous flow within the tank, a measure needed to ensure good water treatment quality. The simulations shown demonstrate that the use of a CFD code is an actual engineering tool and has led to practical recommandations for the construction of chlorination tanks.
