Resumo: | The significant growth of the industrial sector in recent decades has led to an increase in the volume of waste, which if not properly destined, could cause serious environmental problems. In the context of aquaculture, liquid effluents with a high organic content are generated in large quantities in the fish processing industries, and if their disposal is carried out improperly, serious damage to the environment is caused. The general objective of this study is to evaluate: the efficiency of removal of COD and BOD, in addition to the influence on pH; alkalinity; chlorides; ammonia; nitrite; nitrate; phosphate; turbidity; total, fixed and volatile solids, from the effluent of fish processing treated by coagulation and sedimentation using the natural chitosan coagulant. pH 5.5 followed by pH 6 showed better results for the use of chitosan coagulant in the process of treatment by effluent coagulation of fish processing industry. Chitosan does not act on the parameters TVS, alkalinity, chlorides, ammonia, nitrite, nitrate, and phosphate, regardless of the dosage used. However, it acts on BOD, COD, TS, TFS and turbidity. Thus, the best dosage of chitosan is 0.25 g L-1 in optimized activity at pH of 5.5. |

No contexto da aquacultura, efluentes líquidos com um alto teor orgânico são gerados em grandes quantidades nas indústrias de processamento de pescado, e, se seu descarte for realizado de maneira inadequada, há sérios prejuízos ao ambiente. O objetivo geral deste estudo foi avaliar: a eficiência de remoção de DQO e DBO, além da influência sobre o pH, a alcalinidade, os cloretos, a amônia, o nitrito, o nitrato, o fosfato, a turbidez, os sólidos totais, fixos e voláteis, bem como do efluente do processamento de pescado tratado por coagulação e da sedimentação, utilizando-se o coagulante natural quitosana. O pH 5,5, seguido pelo pH 6, apresentou melhores resultados para uso do coagulante quitosana no processo de tratamento por coagulação de efluente de indústria de processamento de pescado. A quitosana não atua sobre os parâmetros STV, alcalinidade, cloretos, amônia, nitrito, nitrato e fosfato, independentemente da dosagem utilizada. Mas atua sobre DBO, DQO, ST, STF e turbidez. Assim, a melhor dosagem de quitosana é 0,25 g L-1 em atividade otimizada no pH de 5,5.CNPq - Conselho Nacional de Desenvolvimento Científico e TecnológicoFAPEMIG - Fundação de Amparo à Pesquisa do Estado de Minas GeraisCAPES - Coordenação de Aperfeiçoamento de Pessoal de Nível SuperiorengUniversidade Federal de Minas GeraisUFMGBrasilVET - DEPARTAMENTO DE MEDICINA VETERINÁRIA PREVENTIVAVET - DEPARTAMENTO DE TECNOLOGIA E INSPEÇÃO DE PRODUTOS DE ORIGEM ANIMALVETER - ESCOLA DE VETERINARIAArquivo Brasileiro de Medicina Veterinária e ZootecniaÁgua - QualidadePescadosJar-testQualidade de águaEfluente de pescadoOreochromis niloticusEmployment of chitosan in the removal of pollutants in fish processing effluentsEmprego de quitosana na remoção de poluentes em efluentes de processamento de pescadoinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttps://www.scielo.br/j/abmvz/a/JNQjX5w9fVPMF3VnQMqjd5g/?lang=enD.
