SUMMARY:

The food industry is today one of the fastest growing activities in the world, due to the great demand for food, which ends up generating a large amount of waste that can contaminate the water. One of the food industries that generates a significant amount of waste is the coconut processing industry. In order to minimize the environmental impact, it is necessary to use some techniques for treating these effluents that are efficient and economically viable. Among these techniques currently studied, the Advanced Oxidative Processes (POAs) have received considerable attention, due to the high efficiency in the treatment of effluents and the low operational cost. Among the POAs, the application of the Fenton reaction, electrochemical, electro-Fenton, photo-Fenton, photoelectro-Fenton, UV / H2O2 and associates has stood out. These techniques have low toxicity and high efficiency for the mineralization of most polluting organic compounds. However, due to the complexity of some effluents, the application of a single technique is not sufficient to adapt the effluent for disposal, therefore, the combination of technologies makes the process even more promising. The objective of this work was to evaluate the application of different POAs in an isolated and associated way as well as to analyze the different operational variables allowing the degradation of the organic matter present in the effluent, and to contribute to the adequacy of the different physical-chemical parameters for the disposal or reuse of the after the treatment. The results indicate that both individual and associated technologies are quite efficient in treating the effluent from the coconut processing industry, with reductions above 65% for Turbidity, COD for each of the proposed treatments. It is expected, at the end of the study, the development of a modular system composed of primary, secondary systems and reactors with photo-electrochemical characteristics, which will be able to treat different types of effluents, so that it can be applied and transferred in the future. industry.
