Abstract

The disinfection of effluents is a technology known for its efficiency in many cities in the world, however if this disinfection is based on oxidation, the composition can affect the treatment efficiency. The variation in the composition and reactivity of the effluent may delay the inactivation of microorganisms due to the presence of competing reactive material to react with the oxidant. In the case of advanced oxidation processes, the formed radicals, especially HO* may have its efficiency affected 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 municipal effluents is very known as well as that the variation in composition and the effluent reactivity may affect the treatment. But still not clear how each component, part of EFOM, inorganic compounds and even chemical compounds of industrial origin can 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 (UV/H2O2) in order to establish the necessary doses for proper disinfection, taking into account the variations of the effluent.
