Kinetic modeling and microbial assessment by fluorescent in situ hybridization in anaerobic sequencing batch biofilm reactors treating sulfate-rich wastewater
(Brazilian Society of Chemical Engineering, 2011)
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 ...
Preparation and characterization of Pd-Co/sulfated zirconia catalysts for no selective reduction by methane
(Elsevier Science, 2008-03)
Palladium and cobalt bimetallic catalysts supported on sulfated zirconia (PdCo/SZ), obtained from different precursors of Pd (nitrate and acetylacetonate), were prepared to study their influence on the selective reduction ...
Boron and sulfate removal using rice husk as filtration material in horizontal flow constructed wetlands microcosms
(North Carolina State University, 2019)
Constructed wetlands (CW) are being explored as an alternative treatment for boron removal. The efficiency of CW strongly depends on the substrate and plants used. A promising and inexpensive substrate is rice husk. This ...
Evaluation of microorganisms with sulfidogenic metabolic potential under anaerobic conditions
(Instituto de Tecnologia do Paraná - Tecpar, 2012-10-01)
The aim of this work was to identify groups of microorganisms that are capable of degrading organic matter utilizing sulfate as an electron acceptor. The assay applied for this purpose consisted of running batch reactors ...
Effect of water vapor over Pd-Co/SZ catalyst for the NO selective reduction by methane
(ELSEVIER SCIENCE BV, 2005-06)
he selective catalytic reduction (SCR) of NO by CH4 in the presence of excess 02 has been studied on Pd-Co, Pd and Co catalysts supported on sulfated zirconia (SZ) and activated in reaction mixture at 700 degreesC. After ...
Remoção de etanol e benzeno em reator anaeróbio horizontal de leito fixo na presença de sulfato
(2007-04-01)
In this study it is reported the operation of a horizontalflow anaerobic immobilized biomass (HAlB) reactor under sulfate-reducing condition which was also exposed to different amounts of ethanol and benzene. The HAIB ...
Effect of water vapor over Pd-Co/SZ catalyst for the NO selective reduction by methane
(Elsevier Science, 2005-01)
The selective catalytic reduction (SCR) of NO by CH4 in the presence of excess O2 has been studied on Pd-Co, Pd and Co catalysts supported on sulfated zirconia (SZ) and activated in reaction mixture at 700 °C. After the ...
Post-treatment of effluents from the sulfate reduction process by anaerobic sequencing batch biofilm reactors
(ELSEVIER SCIENCE BV, 2009)
The main objective of this research was to evaluate the potential use of a bench-scale anaerobic sequencing batch biofilm reactor (ASBBR) containing mineral coal as inert support for removal Of Sulfide and organic matter ...
Sulfate reduction, molecular diversity, and copper amendment effects in bacterial communities enriched from sediments exposed to copper mining residues.
(2009)
Sulfate-reducing bacterial communities from coastal sediments with a long-term exposure to copper (Cu)-mining residues were studied in lactate enrichments. The toxicity of excess copper may affect sulfate-reducing bacterial ...
