1. THERMOPHILIC BIOMETHANE PRODUCTION BY VINASSE IN AN AnSBBR: START-UP STRATEGY AND PERFORMANCE OPTIMIZATION
Abstract Thermophilic anaerobic digestion treatment of industrial wastewater generated at high temperatures can be used as an alternative for environmental pollution control and bioenergy production. Therefore, this study investigated thermophilic anaerobic reactors containing immobilized biomass (AnSBBR) to treat vinasse for methane production, in batch and

2. Population Changes of Eubacteria, Sulfate-Reducing Bacteria and Methanogenic Archaea in an Anaerobic Reactor Processing Ethanol Distillery Vinasse
Abstract The microbiological characterization by molecular techniques (DGGE and quantitative PCR) of Archaea, Bacteria domain and sulfate-reducing bacteria (SRB) from a laboratory scale Up-flow Anaerobic Sludge Blanket (UASB) processing sugar cane vinasse was performed during the operational phase with increasing organic loads. The organic load removal effic

3. METHANE PRODUCTION FROM CASSAVA STARCH WASTEWATER IN PACKED-BED REACTOR AND CONTINUOUS FLOW
ABSTRACT The aim of this study was to evaluate the behavior of an anaerobic reactor of packed-bed and continuous flow, in relation to the biogas and methane production and the removal of organic load, from the wastewater of cassava starch extraction. For this purpose, were tested, in a reactor with a useful volume of 2.82 L and support mean of polypropylene

4. AnSBBR with circulation applied to biohydrogen production treating sucrose based wastewater: effects of organic loading, influent concentration and cycle length
An anaerobic sequencing batch biofilm reactor (AnSBBR) containing immobilized biomass and operating with recirculation of the liquid phase (total liquid volume 4.5 L; treated volume per cycle 1.9 L) was used to treat sucrose-based wastewater at 30 ºC and produce biohydrogen. The influence of applied volumetric organic load was studied by varying the influen

5. Influência da carga orgânica na produção de biohidrogênio em ASBBR com agitação tratando água residuária sintética / Influence of influent concentration and feed time on biohydrogen production in an ASBBR with agitation treating sucrose based wastewater
A mechanically stirred anaerobic sequencing batch reactor containing immobilized biomass treated sucrose-based synthetic wastewater to produce biohydrogen. The system was inoculated with sludge from an anaerobic methanogenic reactor. The following have been assessed: production of biohydrogen, yield per applied and removed load, reactor stability and efficie

6. Effect of organic load, shock load, feeding time and alkalinity supplementation in an ASBBR with recirculation for cheese whey treatment / Influência da carga orgânica, da carga de choque, do tempo de alimentação e da suplementação de alcalinidade em um ASBBR com recirculação para tratamento de soro de queijo
Neste trabalho avaliou-se o desempenho de um reator anaeróbio operado em batelada seqüencial e contendo biomassa imobilizada (ASBBR) em espuma de poliuretano quando submetido a diferentes tempos de alimentação e cargas orgânicas volumétricas, além da aplicação de cargas de choque orgânicas. O reator, com mistura por recirculação da fase líquida

8. Tratamento de lixiviado através de filtro anaeróbio associado a membrana de microfiltração
Nowadays, the use of membrane bioreactors (MBRs) has been researched in many places of the world to treat different kinds of wastewater. The use of MBRs has advantages over other processes when the main focus is on the reuse of wastewater, small areas for wastewater treatment plant or restricted laws conditions. Commonly, the MBRs have been designed with sus

9. 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
