Dissolved methane recovery from anaerobic effluents using hollow fibre membrane contactors [PDF]

open access: yes, 2015
Hollow fibre membrane contactor (HFMC) systems have been studied for the desorption of dissolved methane from both analogue and real anaerobic effluents to ascertain process boundary conditions for separation.

UASB reactor for domestic wastewater treatment at low temperatures: a comparison between a classical UASB and hybrid UASB-filter reactor

open access: yesWater Science and Technology, 2004
The performance of an upflow anaerobic sludge blanket (UASB) reactor and a hybrid UASB-filter reactor was investigated and compared for the treatment of domestic wastewater at different operational temperatures (28, 20, 14 and 10¡C) and loading rates. For each temperature studied a constant CODt removal was observed as long as the upflow velocity was ...

In dubio pro lector. Ambigüedad narrativa y duda razonable en el relato “En un bosque” de Ryunosuke Akutagawa

open access: yesForo, Revista de Derecho, 2020
Entre otros, hay dos recursos narrativos para la construcción retórica de la ambigüedad narrativa; el “narrador no fiable” y el “narratario”. Este artículo estudia la especificidad combinada de los dos procedimientos en el cuento “En un bosque” (1921 ...

Bioaugmentation of UASB reactors with immobilized Sulfurospirillum barnesii for simultaneous selenate and nitrate removal [PDF]

open access: yes, 2009
Whole-cell immobilization of selenate-respiring Sulfurospirillum barnesii in polyacrylamide gels was investigated to allow the treatment of selenate contaminated (790¿µg Se¿×¿L-1) synthetic wastewater with a high molar excess of nitrate (1,500 times) and

Anaerobic Codigestion of Municipal Wastewater, Landfill Leachate, and Crude Glycerin: Process Stability and Methane Yield Assessment Using a Screening Design [PDF]

open access: yesWater Environ Res
Anaerobic codigestion of municipal wastewater with landfill leachate and crude glycerin can achieve near‐theoretical methane yields (0.349 L NCH4/g tCODadd). An optimal mixture of 2% leachate and 1% glycerin was identified, as higher glycerin content negatively impacted performance, highlighting the criticality of substrate balance for energy recovery.

Phosphate removal in agro-industry: pilot- and full-scale operational considerations of struvite crystallization [PDF]

open access: yes, 2009
Pilot-scale struvite crystallisation tests using anaerobic effluent from potato processing industries were performed at three different plants. Two plants (P1 & P2) showed high phosphate removal efficiencies, 89 + 3% and 75 + 8%, resulting in final ...

Comparison of three types of anaerobic granular sludge for treating pharmaceutical wastewater

open access: yesJournal of Water Reuse and Desalination, 2018
Three types of anaerobic granular sludge for treating chemical synthesis-based pharmaceutical wastewater were compared: (1) an up-flow anaerobic sludge blanket (UASB) filled with polyvinyl alcohol (PVA) gel beads (UASB-PVA); (2) a UASB filled with ...

Cobalt toxicity in anaerobic granular sludge: influence of chemical speciation [PDF]

open access: yes, 2008
The influence of cobalt speciation on the toxicity of cobalt to methylotrophic methanogenesis in anaerobic granular sludge was investigated. The cobalt speciation was studied with three different media that contained varying concentrations of complexing ...
