Impacto ambiental e sustentabilidade em ETE sanitária de indústria siderúrgica: estudo de caso no Ceará

Abstract

With the increasing environmental concerns and the need for more sustainable industrial management, the treatment of sanitary effluents in industrial plants has become a crucial topic for mitigating environmental impacts. This study examines the efficiency and operational challenges of a Sewage Treatment Plant (STP) in a steel industry located in Ceará, addressing the physical-chemical and biological processes employed. In addition to reviewing the literature on effluent treatment, operational data from the plant were analyzed, identifying bottlenecks and opportunities for optimization. The results indicate that the current system partially meets regulatory requirements but faces challenges in nutrient removal and the utilization of generated biogas. As alternatives, the implementation of complementary processes is suggested to improve efficiency and reduce environmental impacts. The study contributes to the enhancement of industrial effluent management, emphasizing the importance of integrated and sustainable solutions.
