Resumo: Whey is a by-product of cheese making, rich in protein, lactose, and minerals, which can be processed and added to new products. The valorization of this by-product generates an effluent, rich in organic matter, which, if not properly treated before disposal in water resources, causes environmental impacts. Anaerobic digestion stands out in the treatment of this effluent, as it presents good results in the removal of organic load, is easy to handle, does not require much space, and generates biogas, which can be used to obtain energy in industry. However, anaerobic digestion does not provide good removal of persistent pollutants, such as nitrogen and phosphorus, requiring the application of post-treatment. Electrocoagulation appears as a method for removing these nutrients, as it does not require pH control, requires less energy, and has low sludge production. Thus, this work addresses a review about the development and application of anaerobic methods as an alternative for the treatment of the effluent obtained in the processing of whey, showing the efficiency of the treatment in the removal of COD and after the application of electrocoagulation in order to remove nutrients like nitrogen and phosphorus.

La valorización de este subproducto genera un efluente, rico en materia orgánica, que, si no se trata adecuadamente antes de su eliminación en los recursos hídricos, causa impactos ambientales. La digestión anaerobia se destaca en el tratamiento de este efluente, ya que presenta buenos resultados en la eliminación de la carga orgánica, es fácil de manejar, no requiere mucho espacio y genera biogás, que puede utilizarse para obtener energía en la industria. Sin embargo, la digestión anaeróbica no proporciona una buena eliminación de contaminantes persistentes, como el nitrógeno y el fósforo, lo que requiere la aplicación del tratamiento posterior. La electrocoagulación aparece como un método para eliminar estos nutrientes, ya que no requiere control de pH, requiere menos energía y tiene una baja producción de lodo. Por lo tanto, este trabajo aborda una revisión sobre el desarrollo y la aplicación de métodos anaeróbicos como una alternativa para el tratamiento del efluente obtenido en el procesamiento del suero, que muestra la eficiencia del tratamiento en la eliminación de DQO y después de la aplicación de electrocoagulación para para eliminar nutrientes como el nitrógeno y el fósforo.O soro de leite é um subproduto da fabricação de queijo, rico em proteína, lactose e minerais, que pode ser processado e agregado a novos produtos. Da valorização desse subproduto gera-se um efluente, rico em matéria orgânica, que se não devidamente tratado antes do descarte nos recursos hídricos, causa impactos ambientais. A digestão anaeróbia destaca-se no tratamento desse efluente, pois apresenta bons resultados na remoção da carga orgânica, é de fácil manuseio, não necessita de muito espaço e gera biogás, que pode ser utilizado para obtenção de energia na indústria. No entanto, a digestão anaeróbia não proporciona boa remoção de poluentes persistentes, como o nitrogênio e fósforo, sendo necessário aplicação de pós-tratamento. A eletrocoagulação surge como um método para a remoção desses nutrientes, pois não necessita de controle de pH, demanda menor energia e tem baixa produção de lodo. Dessa forma, esse trabalho aborda um review acerca do desenvolvimento e aplicação de métodos anaeróbios como alternativa para o tratamento do efluente obtido no beneficiamento do soro de leite, mostrando a eficiência do tratamento na remoção de DQO e após a aplicação da eletrocoagulação visando a remoção de nutrientes como nitrogênio e fósforo.Research, Society and Development2020-09-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/7509Research, Society and Development; Vol. 9 No. 9; e623997509Research, Society and Development; Vol. 9 Núm. 9; e623997509Research, Society and Development; v. 9 n. 9; e6239975092525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/7509/6821Copyright (c) 2020 Camila Favretto de Souza; Marcelo Hemkemeierhttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessFavretto de Souza, CamilaHemkemeier, Marcelo2020-09-18T01:42:11Zoai:ojs.pkp.sfu.ca:article/7509Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:30:12.666295Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
