SUMMARY:

Appointed as one of the most polluting industries in the world, the textile industry is also responsible for the generation of the highest volume of residual effluents. The external effluents contain large quantities of corants that are highly toxic, carcinogenic, persistent and represent a great threat to the environment and to human health, also requiring adequate treatment before being discharged from our receiving bodies. In this context, in search of technologies capable of minimizing the effects generated by these pollutants, the attention of the scientific society is increasingly becoming more and more necessary. Thinking about it, the Advanced Oxidative Electrochemical Processes (PEOAs) offer a promising approach to prevent two problems caused by this type of effluent, including the use of electrochemical reactors in order to optimize these processes. The present work seeks to characterize the eletrochemical reaction of continuous flux with different starts and study its application using the electro-oxidation / Eletro-Fenton process of degradation of the synthetic Corant Alaranjado de Metila (AM) for the best condition according to the mass transfer coefficient, assessing corrode and decay removal from core concentration over a long period of time. Through the study of hydrodynamics of the reactor, it is possible to observe a predominantly turbulent scorching regime for situations with an experimental mass transport constant superior to or theoretical, indicating that mass transfer is not homogeneous due to the presence of electrode gases. Through the analysis of core degradation and core removal, it is possible to analyze that the difference in relation to the value of the mass transfer coefficient does not significantly affect our efficiency results, since the final values are approximate both for the valve situation ( melhor condição) quanto for a situation with vazão i (pior condição). Furthermore, with little influence two K values can also be observed in the electrogeration of hydrogen peroxide.
