Studies and comparative analyses of consumption, availability and environmental impact have shown that in many parts of the world, it is impossible to consume water without it being subjected to appropriate treatments and that various emissions are polluted due to the negligent disposal of water after its use. More and more financial and technological investments are being safeguarded in order to achieve an adequate sanitary security and preservation of the environment. The industry in general, is characterized as one of the largest consumers of water and consequently, end up being the ones that generate more liquid effluents in their production process. Based on this premise, it is necessary to elaborate and study efficient projects and technologies that can guarantee the quality of this generated effluent, to ensure the quality of the receiving water body when this effluent is discarded and so that it complies with the standards required by Environmental Legislation. The objective of this work was to analyze an effluent generated by a given company, to characterize this effluent in order to verify its parameter in accordance with the environmental requirements available in the state of Bahia and, based on this analysis, to study the type of technology that should be used for this effluent in order to reduce the parameter present in this effluent so that it complies with the demanding standards to release it to the receiving body without causing environmental damage and public health.Acesso AbertoEfluente líquidoLegislação ambientalSaúde públicaIndústriasParâmetro de lançamentoQualidade de águaLiquid effluentEnvironmental legislationPublic healthIndustriesRelease parameterWater qualityTrabalho de Conclusão de CursoEngenhariasEngenharia Química
