The disinfection of wastewater is a technology recognized for its efficiency in many cities of the world, however if that disinfection is based on oxidation, the composition of the effluent can affect the treatment efficiency. The variation in reactivity and composition of the effluent can delay the inactivation of microorganisms due to the presence of competing reactive material to react with oxidants. For advanced oxidation processes, the radicals formed, mainly HO* may have affected their efficiency by varying the reactivity of organic matter (EFOM - effluent organic matter) and inorganic compounds such as carbonates and nitrates. Currently, the potential of oxidative processes to disinfect effluents is known as well as that the variation in composition and reactivity of the effluent can affect the treatment. However, it is still not clear how each component, components of EFOM, inorganic compounds and even chemical compounds of industrial origin may affect the process. This project proposes to study the influence of the main components of the effluent in the disinfection process by advanced oxidation processes (ozonation and UV/H2O2) in order to establish the doses required for proper disinfection taking into account variations in the effluent.
