Anaerobic Digestion Performance and Microbial Community Structures in a Pilot-Scale Up-Flow Anaerobic Sludge Blanket (UASB) Treating Distillery Wastewater. [PDF]

Water Environ Res
This study demonstrates stable anaerobic treatment of high‐strength distillery wastewater in a pilot‐scale UASB reactor, achieving 86% COD removal and 75% methane yield at an OLR of 10.0 kg COD/m3/d. Microbial analysis highlights the role of syntrophic bacteria and hydrogenotrophic methanogens in enhancing performance under high OLR, offering insights ...

Phosphorus Recovery From Wastewater Through Anaerobic Digestion Under Sub-Supersaturation Conditions. [PDF]

Water Environ Res
The presence of organic matter, such as NaAc, proteins, and urea, in wastewater favors phosphorus recovery in UASB reactors at a relatively low phosphorus concentration of 30 mg/L. The hydrolysis of these organic compounds creates localized supersaturation, facilitating the formation of phosphate salts.

Novel Respirometry Measurement and Comparison of Monod Kinetic Constants and Methanogen Concentrations for 27 Full-Scale Anaerobic Bioreactors. [PDF]

Water Environ Res
Kinetic coefficients (km and Ks) and methanogen concentrations (Xac and Xh2) for anaerobic bioreactors were measured using novel respirometry. Values are needed to understand anaerobic biotechnology and modeling. Ostensibly due to microbial community differences, km and X varied over orders of magnitude.

Activation of drought tolerant traits in crops: endophytes as elicitors

Plant Signaling & Behavior, 2022
Drought challenges crop production worldwide. The issue is aggravated by frequent drought episodes and unpredictable rainfall patterns associated with global climate change. While the efforts to breed drought-resistant crop varieties are progressing, the

Hydrolysis and Methanogenesis in UASB-AnMBR Treating Municipal Wastewater Under Psychrophilic Conditions: Importance of Reactor Configuration and Inoculum

Frontiers in Bioengineering and Biotechnology, 2020
Three upflow anaerobic sludge blanket (UASB) pilot scale reactors with different configurations and inocula: flocculent biomass (F-UASB), flocculent biomass and membrane solids separation (F-AnMBR) and granular biomass and membrane solids separation (G ...

Diversity and Abundance of Microbial Communities in UASB Reactors during Methane Production from Hydrolyzed Wheat Straw and Lucerne

Microorganisms, 2020
The use of straw for biofuel production is encouraged by the European Union. A previous study showed the feasibility of producing biomethane in upflow anaerobic sludge blanket (UASB) reactors using hydrolyzed, steam-pretreated wheat straw, before and ...

Granulation in UASB-Reactors

Water Science and Technology, 1983
The influence of the sludge loading rate, the addition of a small amount of granular sludge to the seed sludge and the effect of the NH4+- and Ca2+-concentration in the influent on the pelletization-process of anaerobic methanogenic sludge in UASB-reactors were studied. Two different types of sludge granules can be obtained with VFA's as feed-solution.

Controle e remoção de sulfetos em reatores anaeróbios tratando esgoto sanitário [PDF]

Revista DAE, 2016
A presente pesquisa objetivou avaliar o desempenho de sistemas anaeróbios quanto à concentração de sulfetos presentes no efluente de reatores UASB. Foram utilizados dois reatores UASB para comparação; em um foi inserido oxigênio na manta de lodo (0,6 a 1,
