1. BIOGAS YIELD AND PRODUCTIVENESS OF SWINE MANURE FOR DIFFERENT REACTOR CONFIGURATIONS
ABSTRACT The progression of the organic loading rate (OLR) up to a certain limit increases biogas production. The limit and operation range vary according to the configuration of the reactor and are associated with other variables that generate different results with respect to biogas yield (BY) and biogas productiveness (BP). The aim of this study was to in

3. 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

4. COMPARISON OF UASB AND FLUIDIZED-BED REACTORS FOR SULFATE REDUCTION
Abstract Reactor hydrodynamics is important for sulfidogenesis because sulfate reduction bacteria (SRB) do not granulate easily. In this work, the sulfate reduction performance of two continuous anaerobic bioreactors was investigated: (i) an upflow anaerobic sludge blanket (UASB) reactor and (ii) a fluidized bed reactor (FBR). Organic loading, sulfate reduct

5. Odor from anaerobic digestion of swine slurry: influence of pH, temperature and organic loading
Farm slurry management from storage and/or treatment is the main source of odors from swine production, which are determined by factors such as operational variations (organic loading), cleaning of facilities and animal diet (pH) or environmental conditions (temperature). The aim of this study was to evaluate the influence of pH, temperature and organic load

6. UASB reactor startup for the treatment of municipal wastewater followed by advanced oxidation process
The present study was done to shorten the start-up time of up-flow anaerobic sludge blanket (UASB) reactor. Two different nutrients were used during the UASB start-up period, which was designed to decrease the hydraulic retention time (HRT) from 48 to 24 and 12 to 6 hrs at average temperatures of 25-34 ºC. In the first stage, start-up was with glucose for 1

7. Characterization of an acidification and equalization tank (AET) operating as a primary treatment of swine liquid effluent
This work evaluated the potential of the acidification equalization tank (AET) used as a primary treatment unit, treating the hog farming wastewater. The treatment system consisted of a degritter with a triangular-notch weir, for measuring the flow, a static sieve, and an acidification and equalization tank (AET), an anaerobic baffled reactor (ABR), an upflo

8. 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

9. Produção de biogás a partir de glicerol oriundo de biodiesel / Biogas production from glycerol generated on biodiesel industry
The Brazilian legislation demands the use of biodiesel mixed with diesel in an increasing rate. This raise on biodiesel production implies also on an increase on generation of glycerol, which is a liquid or semi-solid waste with high concentration of salts (approximately 46.1 g\ CL POT.-\ /L) and organic matter (1260 gCOD/L in average). Despite being widely

10. Comportamento hidrodinâmico e cinético dos reatores anaeróbios compartimentado (RAC) e manta de lodo (UASB) operados em série / The hydrodynamic and kinetic bahavior of the anaerobic baffled reactor (ABR) and upflow anaerobic Sludge blanket (UASB) operated in serie
The aim of this research was to determine the hidrodymanic and kinetics behavior of a pilot system plant, treating swine liquid effluent, installed in the Zootechnical Department of the Federal University of Lavras. The pilot system was composed by several units working in series, such as sand retention box (SRB), static sieve (SS), acidification and equaliz

11. Peptidolytic microbial community of methanogenic reactors from two modified UASBs of brewery industries
We studied the peptide-degrading anaerobic communities of methanogenic reactors from two mesophilic full-scale modified upflow anaerobic sludge blanket (UASB) reactors treating brewery wastewater in Colombia. Most probable number (MPN) counts varied between 7.1 x 10(8) and 6.6 x 10(9) bacteria/g volatile suspended solids VSS (Methanogenic Reactor 1) and 7.2
