Resumo
Este trabalho de conclusão de curso aborda a crescente relevância do tratamento de
efluentes na indústria têxtil brasileira, um setor que, apesar de sua importância
econômica, é uma das principais fontes de poluição hídrica devido ao volume e à
complexidade de seus resíduos líquidos. O objetivo principal foi avaliar a eficiência
dos processos de membrana, especificamente o sistema VRM (Vacuum Rotational
Membranes), em comparação com métodos convencionais, como o sistema de lodo
ativado (CAS), na remoção de contaminantes de efluentes têxteis. A metodologia
envolveu análise comparativa de parâmetros como Demanda Química de Oxigênio
(DQO), Demanda Bioquímica de Oxigênio (DBO5), cor e turbidez, utilizando amostras
reais da indústria ao longo de quinze dias. Os resultados demonstraram a
superioridade do sistema VRM, enquanto o CAS alcançou 83,7% de eficiência na
remoção de DQO, o VRM atingiu 91,1%. Em relação DBO5, o VRM registrou uma
média de 18 mg/L, atendendo à legislação (máxima de 60 mg/L), diferentemente do
CAS, que apresentou 92 mg/L. Adicionalmente, o VRM mostrou-se significativamente
mais eficaz na redução da cor e da turbidez dos efluentes. Concluiu-se que os
processos de membrana oferecem uma solução mais eficiente e sustentável para o
tratamento de efluentes têxteis, superando os padrões regulatórios e promovendo o
reuso da água. Essa tecnologia representa um avanço crucial para a conservação de
recursos hídricos e para o desenvolvimento de práticas industriais mais responsáveis
e economicamente viáveis
This undergraduate thesis addresses the growing relevance of wastewater treatment in the Brazilian textile industry, a sector which, despite its economic importance, is one of the main sources of water pollution due to the volume and complexity of its liquid waste. The primary objective was to evaluate the efficiency of membrane processes, specifically the VRM system (Vacuum Rotational Membranes), in comparison with conventional methods such as the activated sludge system (ASS), in the removal of contaminants from textile effluents. The methodology involved a comparative analysis of parameters such as Chemical Oxygen Demand (COD), Biochemical Oxygen Demand (BOD5), color, and turbidity, using real industry samples over a fifteen-day period. The results demonstrated the superiority of the VRM system: while the ASS achieved 83.7% efficiency in COD removal, the VRM reached 91.1%. Regarding BOD5, the VRM recorded an average of 18 mg/L, complying with legislation (maximum of 60 mg/L), unlike the ASS, which showed 92 mg/L. Additionally, the VRM proved to be significantly more effective in reducing both color and turbidity of the effluents. It was concluded that membrane processes provide a more efficient and sustainable solution for textile effluent treatment, surpassing regulatory standards and promoting water reuse. This technology represents a crucial advancement for the conservation of water resources and the development of more responsible and economically viable industrial practices.
