Resumo: | Whey is a by-product of cheese making, rich in lactose, protein and minerals and of economic importance. From the processing of whey, there remains an effluent to be treated, rich in organic matter and nutrients, which needs adequate treatment to minimize the environmental impacts of its release. Anaerobic treatment proves to be a good treatment alternative for this type of effluent due to its ability to remove organic matter, however, this treatment is not good at removing nutrients, requiring a complementary treatment. In this sense, electrocoagulation can be an alternative due to its capacity to reduce sludge volume and good removal of nutrients. Thus, the objective of this work is to evaluate whether electrocoagulation, as a method of anaerobic after-treatment of effluent generated in the processing of whey, is effective in removing COD and phosphorus. The present work evaluated the efficiency in the removal of organic charge and nutrients through the combination of anaerobic and electrolytic processes in the treatment of effluent from the processing of whey. In the treatment in anaerobic reactor, retention time of 3 and 10 days and temperatures of 15, 25 and 35ºC were used. The effluent treated from this process was sent for treatment in an electrolytic reactor, being studied the type of electrode (Iron and Aluminum), the treatment time (20 and 40 min) and the current density (0.5 and 1.0 A / m2). The anaerobic treatment proved to be efficient, obtaining removal greater than 99% in apparent color, 97% in turbidity and 98% in COD at temperatures of 25 and 35ºC for a period of 10 days. The same behavior was not observed in the removal of phosphorus, proving the need for post-treatment. The best COD removal was with an iron electrode reaching 91% and phosphorus with an aluminum electrode, obtaining 64% removal, demonstrating that the electrolytic treatment after anaerobic treatment is an efficient method of after treatment for the whey effluent. |

Do processamento do soro de leite, resta um efluente a ser tratado, rico em matéria orgânica e nutrientes, que precisa de tratamento adequado para minimizar os impactos ambientais do seu lançamento. O tratamento anaeróbio demonstra ser uma boa alternativa de tratamento para esse tipo de efluente devida a sua capacidade de remoção de matéria orgânica, contudo, esse tratamento não tem boa eficiência na remoção de nutrientes, sendo necessário um tratamento complementar. Neste sentido, a eletrocoagulação pode uma alternativa devida a sua capacidade de redução de volume de lodo e boa remoção de nutrientes. Desta forma, o objetivo deste trabalho é avaliar se a eletrocoagulação, como método de pós tratamento anaeróbio de efluente gerado no processamento do soro de leite é eficaz na remoção de DQO e fósforo. O presente trabalho avaliou a eficiência na remoção de carga orgânica e nutrientes através da combinação de processos anaeróbio e eletrolítico no tratamento de efluente do beneficiamento do soro de leite. No tratamento em reator anaeróbio, foi utilizado tempo de retenção de 3 e 10 dias e temperaturas de 15, 25 e 35ºC. O efluente tratado desse processo, foi encaminhado para tratamento em um reator eletrolítico, sendo estudado o tipo de eletrodo (Ferro e Alumínio), o tempo de tratamento (20 e 40 min) e a densidade de corrente (0,5 e 1,0 A/m2). O tratamento anaeróbio demonstrou ser eficiente, obtendo remoção superior a 99% na cor aparente, 97% na turbidez e 98% na DQO nas temperaturas de 25 e 35ºC pelo período de 10 dias. O mesmo comportamento não foi observado na remoção de fósforo, comprovando a necessidade de pós tratamento. A melhor remoção de DQO foi com eletrodo de ferro alcançando 91% e de fósforo com eletrodo de alumínio, obtendo 64% de remoção, demonstrando que o tratamento eletrolítico após tratamento anaeróbio é um método eficiente de pós tratamento para o efluente do soro de leite.Submitted by Aline Rezende (alinerezende@upf.br) on 2021-06-23T19:50:46Z No. of bitstreams: 1 2021CamilaFavrettodeSouza.pdf: 1021738 bytes, checksum: adb5f867be6cf633e11f6eb00453d8ef (MD5)Made available in DSpace on 2021-06-23T19:50:46Z (GMT).

Whey is a by-product of cheese making, rich in lactose, protein and minerals and of economic importance.
