Multi-environment reactors are an innovative alternative to simplify conventional Biological Nutrient Removal (BNR) treatment trains as they are more compact and can adapt to existing quality requirements. Concretely, AnoxAn unifies the anaerobic and anoxic zones of conventional BNR processes in a continuous upflow sludge blanket reactor. However, the multi environmental zoning and singular elements configuration give rise to a complex hydrodynamic behaviour that interferes in the desired biological operation of the reactor. Therefore, in this thesis, a comprehensive hydrodynamic assessment of AnoxAn is carried out, and the influence of the hydraulic behaviour on the biological efficiency of the process is evaluated. For that purpose, a Computational Fluid Dynamics (CFD) based numerical tool is developed with the open source toolbox OpenFOAM®, and a hydrodynamic optimization methodology for multi-environment reactors is proposed. The results obtained in this work have contributed to the development of technological and operational improvements of AnoxAn.
