We apply CFD simulation and experimental validation to optimise processes in ETAP and EDAR.

Over 100 installations modelled with CFD and tracer tests, achieving up to 40% less dead volume.

We apply advanced simulation using Computational Fluid Dynamics (CFD) to analyse and optimise the operation of both potable water treatment plants (ETAP) and wastewater treatment plants (EDAR). Through mathematical models that integrate hydraulic processes, and physicochemical and biological reactions, we are able to reproduce the real behaviour of the different process units and anticipate their performance in different scenarios.

Our methodology combines modelling with experimental validation, using tracer tests and in situ measurements, which allows us to adjust the models to real operating conditions. This helps us identify inefficiencies such as hydraulic short-circuiting or dead volumes, as well as optimise key parameters such as mixing, aeration, or reagent dosing.

We have applied this solution in over 100 full-scale installations, both in Spain and Europe, ranging from decanters, biological reactors and digesters to large-capacity tanks or distribution networks. In these projects, we have achieved significant improvements such as a reduction in dead volumes of up to 40 %or an increase in mixing efficiency of around 30 %, contributing to more efficient and stable plant operation.

As a result, we optimise energy and reagent consumption, reduce uncertainty in decision-making, and facilitate the planning of expansions or new designs. In this way, we reinforce data- and knowledge-based management, which improves operational efficiency and allows us to move towards a more sustainable model for the integrated water cycle.
