3. Avaliação de desempenho de reator anaeróbio-aeróbio com recirculação da fase líquida no tratamento de água residuária proveniente de abatedouro de aves / Performance evaluation of an anaerobic-aerobic reactor with recycle of the liquid phase for treatment of poultry slaughterhouse wastewater
This work aimed to evaluate the performance of an up-flow fixed bed reactor, operated in a continuous way, using expanded clay and polyurethane foam as supports for immobilization of the biomass, for treatment of poultry slaughterhouse wastewater. Initially, the reactor was operated under anaerobic and anaerobic-aerobic conditions for the treatment of poultr

4. Reator de leito expandido em escala plena com zonas anaeróbia e aeróbia sobrepostas: remoção conjunta de matéria orgânica e nutrientes e estudo do comportamento microbiológico do biofilme, por respirometria e microsensor de OD / Full scale expanded bed reactor with overlaid anaerobic and aerobic zones: joint removal of organic matter and nutrients and the study of microbiological biofilm behavior and DO microsensor
The current research aimed the development of a 159 M POT.3total volume biological reactor, with a expanded and partially aerated granular coal bed (activated and anthracite), to promote organic matter and nutrients (N and P) removal from wastewater due to the maintenance of anaerobic and aerobic environments, stratified throughout the height of the reactor

5. Coagulation/precipitation of effluents from anaerobic expanded bed reactor and activated sludge system preceded by UASB reactor, with particle removal by sedimentation or flotation / Coagulação/precipitação de efluentes de reator anaeróbio de leito expandido e de sistema de lodo ativado precedido de reator UASB, com remoção de partículas por sedimentação ou flotação
The anaerobic reactors of modern conception (e.g., UASB and RALEx) remove from 65 to 75% of sanitary wastewater organic matter with relatively low construction, operation, and maintenance costs, in comparison with conventional aerobic processes. Nevertheless, that reactors are usually little efficient in nutrient removal and their effluents may present relat

6. Avaliação do uso da banda de rodagem de pneus inservíveis triturada como suporte ao desenvolvimento de biofilmes em um reator anaeróbio de leito expansível / Granulated tread of scrap tires as support for the development of biofilms in an expanded bed anaerobic reactor
The present research had as objective the assessment of granulated tread of scrap tires (GTST) as support for the development of biofilms in an expanded bed anaerobic reactor (EBAR), in full scale, with a total volume of 32m3, employed for wastewater treatment. The use of this material as support was presented as an innovating proposal, with a high applicati

7. Ti O IND.2 heterogeneous photocatalysis in secondary wastewater treatment / Fotocatálise heterogênea com Ti O IND.2 aplicada ao tratamento de esgoto sanitário secundário
The heterogeneous photocatalysis with Ti O IND.2 and solar radiation in secondary wastewater treatment to remove organic matter and microorganisms was investigated. A glass plate (approximate 0.48 M POT.2 ) with immobilized titanium dioxide (10 g/ M POT.2 ) was operated in different flow rates (15; 22.5 and 30 L/h) and angles in relation to horizontal (2, 12

8. Tratamento anaerÃbico de efluentes gerados em matadouros de bovinos / Anaerobic Treatment of Effluents from Slaughterhouses
Generation of wastes in the agroindustrial activities is very significant, especially in the case of the slaughterhouses. In Pernambuco, the slaughterhouses are considered as an important contributor for the growing pollution of the receiving water bodies. Despite the available technology for effluents treatment, they are seldom used. The present work evalua

10. Application of coagulants to anaerobic expanded bed reactor influent fed by domestic wastewater / Aplicação de coagulantes no afluente de reator anaeróbio de leito expandido alimentado com esgoto sanitário.
Os reatores anaeróbios de tratamento de esgoto possibilitam elevada remoção de matéria orgânica, com menor custo em comparação com os processos aeróbios. Entretanto, esses reatores geralmente são pouco eficientes na remoção de nutrientes e seu efluente pode apresentar valores relativamente elevados de DQO e de sólidos suspensos. Por isso, investi

11. Batch Tests To Determine Activity Distribution and Kinetic Parameters for Acetate Utilization in Expanded-Bed Anaerobic Reactors
Batch tests to measure maximum acetate utilization rates were used to determine the distribution of acetate utilizers in expanded-bed sand and expanded-bed granular activated carbon (GAC) reactors. The reactors were fed a mixture of acetate and 3-ethylphenol, and they contained the same predominant aceticlastic methanogen, Methanothrix sp. Batch tests were p

12. Cluster Structure of Anaerobic Aggregates of an Expanded Granular Sludge Bed Reactor
The metabolic properties and ultrastructure of mesophilic aggregates from a full-scale expanded granular sludge bed reactor treating brewery wastewater are described. The aggregates had a very high methanogenic activity on acetate (17.19 mmol of CH4/g of volatile suspended solids [VSS]·day or 1.1 g of CH4 chemical oxygen demand/g of VSS·day). Fluorescent i
