13. Caracterização de Produtos Microbianos Solúveis (SMPs) em Reatores Aeróbio e Anaeróbio de Bancada em Diferentes Condições Operacionais
Biological wastewater treatment is characterized by aerobic and/or anaerobic bacteria that degrade pollutant organic matter and parameters such as chemical oxygen demand (COD) are usually used to assess these treatments efficiency. Biological reactors effluent COD is comprised not only of influent compounds that have not been degraded, but also of some compo

14. Tratamento de esgoto sanitário em um reator de leito expandido em escala plena, operado com regiões anaeróbia e aeróbia sobrepostas / Treatment of sanitary wastewater in a full scale expanded bed reactor, operated with overlap anaerobic and aerobic regions
This present research had as main objective the evaluation of the performance of a full scale expanded bed reactor (159.0 M POT.3), operated under anaerobic and overlapping anaerobic-aerobic, treating sanitary wastewater. As specific objectives, it was evaluated using commercial sand to complement the bed of particles and distribution of material support alo

15. Aerobic biofilms for nitrogen removal in flow cells, submitted to different superficial velocities and loading rates / Biofilmes aeróbios para remoção de nitrogênio em células de fluxo, submetidos a diferentes velocidades superficiais e taxas de carregamento
The post-treatment of anaerobic reactor effluents, such as the Upflow Anaerobic Sludge Blanket (UASB), in most applications, is necessary, since this kind of biological treatment promotes BOD removal ranging from 60 to 75% and it has low efficiency in nitrogen and phosphorous removal. Nitrogen removal is usually carried out in a conventional way through nitr

16. RemoÃÃo biolÃgica de nitrogÃnio de efluente avÃcola usando reator em batelada sequÃncial
Slaughterhouses and bird cold storage processing plants stand out as large polluters, particularly because of the large amounts of waste rich in organic substances, solids, oils and greases, nutrients, specially nitrogen and phosphorus. Nitrogen compounds removal from wastewater is usually accomplished through biological processes, by nitrification under aer

17. Effect of ammonia load on efficiency of nitrogen removal in an SBBR with liquid-phase circulation
The removal of biological nitrogen from a synthetic wastewater with different ammonium nitrogen concentrations (50 and 100 mgN-NH4+/L) by a nitrification and denitrification process using a sequencing batch biofilm reactor (SBBR) with liquid-phase circulation was studied. The system with a total working volume of 4.6 L (3.7 L in the reactor and 0.9 L in the

18. Utilização do metano como doador de elétrons para remoção de nitrogênio via nitrificação e desnitrificação em reator operado em bateladas seqüenciais / Nitrogen removal by biological nitrification and denitrification using methane as electron donor in a sequencing batch aerobic/anoxic reactor
Nitrogen removal via biological nitrification and denitrification was studied in a sequencing batch reactor submitted to aerate and anoxic periods. Methane was added as electron donor for denitrification in the anoxic periods. Different operational and nutritional conditions referred to as stages in this text were tested aiming to achieve the best nitrogen r

19. CARACTERIZAÇÃO, POR ESPECTROMETRIA DE MASSAS, DOS MICROPOLUENTES PRESENTES NO ESGOTO BRUTO E NOS EFLUENTES DE UM SISTEMA DE TRATAMENTO COMBINADO ANAERÓBIO-AERÓBIO
Pharmaceuticals and personal care products arrive at wastewater treatment plants after disposal, where arent completely degraded. There are only a few Brazilian studies which look for those organic micropolutants on the domestic sewage, as well as their removal in effluent treatment systems. This work developed an analytical methodology in order to identify

20. BIOGRÂNULOS AERÓBICOS EM REATOR SEQÜENCIAL EM BATELADA PARA O TRATAMENTO DE EFLUENTE DE BIODIGESTOR PROVENIENTE DA SUINOCULTURA / AEROBIC BIOGRANULES IN SEQUENTIAL BATCH REACTOR FOR THE TREATMENT OF ANAEROBIC DIGESTER EFFLUENT FROM THE PIGGISH
A fermentação dos dejetos de suínos em biodigestores vem sendo recomendada para o aproveitamento energético do metano (CH4) produzido, diminuindo assim a emissão desse gás de efeito estufa para a atmosfera. Entretanto, a água residual (efluente de biodigestor), se despejada em cursos dágua, pode causar poluição pois apresenta, ainda, Demanda Quími

21. Sistema combinado aplicado ao tratamento de esgoto sanitario contendo formaldeido : desempenho e avaliação biomassa / Domestic wastewater treatment containing formaldepyhe byan anaerobic filter followed by a biological aerated filter : performance and biomass valuation
This study was developed with the intent to verify the treatability of domestic wastewater containing formaldehyde in a combined system formed by an Anaerobic Filter followed by a Biological Aerated Filter, each one with 12 h of hydraulic retention time (HRT). The reactor s performance was monitored by different influent formaldehyde concentration applied in

22. CARACTERIZAÇÃO E TRATABILIDADE DOS ESGOTOS PRODUZIDOS PELO CAMPUS DA UNIVERSIDADE FEDERAL DE OURO PRETO MG / Characterization, quantification and treatability of the wastewater produced by the Federal University of Ouro Preto MG
The aim of this work was to assess the presence of toxic chemicals in the wastewater from university laboratories, which would be improperly discharged into sinks together whit waste from bathrooms and canteens of the campus buildings of UFOP (Federal University in Ouro Preto, Brazil). This work also aimed at determining the aerobic and anaerobic biodegradab
