They are many the challenges to which confront at present the companies devoted to the treatment of drinkable and residual water to the hour to achieve the ecological aims and of energetic saving, hygiene and efficiency imposed to community level, state and European. On the one hand, they have to adapt to an environingingmental legislation increasingly strict regarding the contribution to the climatic change, but besides, the coyuntura economic current forces them to answer to some exigencias of hygiene and efficiency of processes with fewer economic resources.

This, joined to the high cost of exploitation and maintenance of the processes of treatment of waters, does that one of the main worries of the most innovative companies in the area of treatment of waters was the one to keep the maximum levels of efficiency in his investments, so much the directed to the development of new systems, as the ones of optimisation of the existent. In this sense, the companies trust increasingly in the use of the simulation for the engineering.

“It exists a strong growth of the technological investment in this market”, ensures Gilles Lebiez, director of ANSYS Iberia, experts in simulation for the engineering. “The numerical simulation is a powerful tool to the hour to understand and test virtually the behaviour of a system before it exist”, adds.

The simulation for the engineering, in the avant-garde of the green “innovation”

The companies have found the solution in the simulation for the engineering. His use allows to the developers of new tools and systems test virtually the operational performance of his designs that, of another form, when treating of projects of engineering specialised of big envergadura, would force to the organisations to face high costs of manufacture and tackle complex physical phenomena.

Are many the appearances that the companies have to take into account to the hour to look for solutions to collect, drain, store, transport, treat, download and distribute the water of safe and effective form. These organisations depend on crowd of physical analyses, like the dynamics of computational fluids (CFD), the hydraulics or the predictions of transfer of mass, for modelar and verify the behaviour and the flows of water under a wide rank of conditions. In words of Gilles Lebiez, “when applying tools of simulation in engineering in the process of design, reduces considerably the need to experience and create physical prototypes, and open strategic roads so that the companies improve his R&D and obtain competitive advantages, offering to his customers the best product to the lower cost”.

Main challenges of the industry

Between the main challenges of the industry of treatment of drinkable and residual water to which can answer more effectively through the simulation for the engineering find :

Reduce the size of the tanks (tanks) without minimising the efficiency of the processes of treatment of water
Modelado of flows of liquid in the reservoirs and preys, including the areas of sedimentación, the zones of stagnation and of the regions of flow of short circuit.
Optimisation of the taxles of mix of the tank and geometries
Measure and improve the efficiency of the disinfection, included the technologies UV
Model of flows of fluent
Maximizar the taxles of transfer of oxygen
Optimise the efficiency of different systems of pumping
Expand the systems of treatment to give fit to greater flows. The model of flow of water inside the pipes and channels
Modelado of flows in manifolds of fango and open channels
Improve the efficiency of turbine of aireación.
