1. META-ANÁLISE DO TRATAMENTO DE DEJETOS SUÍNOS EM REATORES ANAERÓBIO DE FLUXO ASCENDENTE COM MANTA DE LODO E REATOR SEQUENCIAL EM BATELADA / META-ANALYSIS OF SWINE WASTE TREATMENT SYSTEMS THROUGH UPFLOW ANAEROBIC SLUDGE BLANKET AND SEQUENCING BATCH REACTORS
The study was performed in order to evaluate, through meta-analysis, the relationship of upflow anaerobic sludge blanket or sequencing batch reactors on the removal efficiency ofpollutant loadin swine waste treatment. The database totaled 76 articles published between 1987 and 2011. The meta-analysis followed three sequential analyses: graphical, correlation

2. Kinetic modeling and microbial assessment by fluorescent in situ hybridization in anaerobic sequencing batch biofilm reactors treating sulfate-rich wastewater
This paper reports the results of applying anaerobic sequencing batch biofilm reactors (AnSBBR) for treating sulfate-rich wastewater. The reactor was filled with polyurethane foam matrices or with eucalyptus charcoal, used as the support for biomass attachment. Synthetic wastewater was prepared with two ratios between chemical oxygen demand (COD) and sulfate

3. Effect of the stirring speed, the type of impeller and the feed strategy in a mechanically stirred pilot-scale anaerobic sequencing batch reactor / Estudo da influência da agitação e da estratégia de alimentação sobre o desempenho de um ASBR em escala piloto aplicado ao tratamento de esgoto sanitário
The objective of this work was to assess the effect of the stirring speed, the type of impeller and the feed strategy in a mechanically stirred pilot-scale (da ordem de1 M POT.3) anaerobic sequencing batch reactor to two configurations: a containing granulated biomass (ASBR) and the other containing immobilized biomass (AnSBBR). Domestic wastewater was treat

4. Biodegradation of linear alkylbenzene sulfonate in anaerobic sequencing biofilm batch reactor with biomass immobilization in charcoal / Degradação de alquilbenzeno linear sulfonado em reator anaeróbio operado em bateladas seqüenciais com biomassa imobilizada em carvão vegetal
This work used an anaerobic sequencing biofilm batch reactor aiming the removal and degradation of the linear alkylbenzene sulfonate (LAS). Biomass from an UASB reactor treating suine wastewater was immobilized in charcoal fragments. The reactor was fed with synthetic substrate with addition of LAS. Feeding happened in four stages: (1) synthetic substrate wi

5. Landfill leachate treatment in sequence anaerobic and aerobic batch reactors systems / Tratamento de lixiviados de aterros sanitários em sistema de reatores anaeróbio e aeróbio operados em batelada seqüencial
Este trabalho avaliou a tratabilidade dos lixiviados do aterro sanitário de São Carlos-SP, utilizando-se reatores biológicos. O experimento foi conduzido à temperatura ambiente, em uma unidade piloto construída no aterro sanitário de São Carlos-SP. Inicialmente foram testados e comparados dois tipos de reatores anaeróbios, cada um com volume total de

6. Tratamento de esgoto sanitário em reatores anaeróbios operados em bateladas seqüenciais e periodicamente aerados / Treatment of domestic sewage in periodically aerated anaerobic sequencing batch reactors
The advance of anaerobic technology for wastewater treatment should be credited in great part to the development of the modern reactors with high rates of organic application, with merit to the ascendant anaerobic filter and mainly to the UASB configuration. The evolution of reactors led to the search to maximize the practical aplication to make the best use

7. Microbiological characterization of the removal and degradation of linear alkylbenzene (LAS) in anaerobic reactors with biofim and planctonics cells / Caracterização microbiológica da remoção e degradação de alquilbenzeno linear sulfonado (LAS) em reatores anaeróbios com biofilme e células planctônicas
The objective of this work was to evaluate the degradation of linear alkylbenzene sulfonate (LAS) in anaerobic conditions. The first experiments were accomplished in reactors in batch fed with different substrates and concentration of LAS. In spite of the surfactant to be adsorbed in the sludge interferences was not observed in the metabolism of anaerobic mi

8. A simplified analysis of granule behavior in ASBR and UASB reactors treating low-strength synthetic wastewater
This work presents an analysis of the changes observed in granule characteristics of sludge in the treatment of synthetic wastewater at a concentration of about 500 mgCOD/L in batch, fed-batch (ASBR) and continuous (UASB) bench-scale reactors under similar experimental conditions. Physical and microbiological properties of the granules were characterized as

9. Avaliação de desempenho do reator anaeróbio em batelada seqüencial (ASBR), contendo biomassa imobilizada em pedra pome, para tratamento de esgoto sanitário / Performance evaluation of a stirred anaerobic sequencing batch reactor containing immobilized biomass in pumice stone for wastewater treatment
The anaerobic sequencing batch reactors (ASBR) with immobilized biomass, that are under development at Mauá Institute of Technology and at São Carlos Engineering School, presented good performance in the wastewater treatment. Recent researches are trying to improve this reactor design and operation. The choice of the support material is one of the importan
