The O3/UV advanced oxidation processes constitute physical-chemical processes recently used as efficient processes of degrading the organic substances and for disinfection purposes within the water treatment and purging technologies. Technically speaking, the O3/UV advanced oxidation systems involve two kinds of distinct processes: the gas/liquid (O3/aqueous solution) transfer, which is a distinct physical step, and the transfer of the ultra-violet radiation photons transfer (λ<310 nm) into the solution and the initiation of a chain of reactions leading both to direct photodegradation processes and to highly reactive OHo radicals species generation processes. This work suggests the elaboration of a numerical template for the advanced oxidation reactors (O3/UV) based on the CFD (Computational Fluid Dynamics) method, by using the FEM (Finite Element Method) for numerically solving the differential equations systems. This template may constitute both the basis for the elaboration of designing methods in the field of water treatment equipment engineering and the modelling basis for studying more complex advanced oxidation systems, which include heterogeneous photocatalysis processes.
