The purpose of this study was to analyze DON changes along denitrification with suspended and attached biomass. Denitrification batch experiments were carried out with activated sludge and biological (kaldnes) carriers. In the batch tests with kaldnes it was used two different mixing velocities to evaluate its influence in DON concentrations. For the batch tests were evaluated COD and DOC concentrations. A comparison of the fate of DON during a denitrification process and the original effluent DON concentration was made. DON determinations oscillate in a range from 0.1 to 1.9 mg/l during a denitrification test. The comparison between DON determinations and the original effluent confirm that DON has a significant portion (about 20%) of the effluent N. The results obtained indicate that DON has a constant behavior along the denitrification process.Faculdade de Ciências e TecnologiaAmaral, LeonorBrandão, DianaRUNRodrigues, Mónica Luís Pereira2014-01-20T17:24:24Z20132013-01-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfhttp://hdl.handle.net/10362/11073enginfo:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2024-03-11T03:45:22Zoai:run.unl.pt:10362/11073Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-20T03:20:01.846347Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse
