Sulfate and metal removal from acid mine drainage using sugarcane vinasse as electron donor: Performance and microbial community of the down-flow structured-bed bioreactor
(2021-06-01)
The down flow structured bed bioreactor (DFSBR) was applied to treat synthetic acid mine drainage (AMD) to reduce sulfate, increase the pH and precipitate metals in solutions (Co, Cu, Fe, Mn, Ni and Zn) using vinasse as ...
Dynamics of sulfidogenesis associated to methanogenesis in horizontal-flow anaerobic immobilized biomass reactor
(ELSEVIER SCI LTD, 2009)
Two bench-scale horizontal anaerobic fixed bed reactors were tested to remove both sulfate and organic matter from wastewater. First, the reactors (R1 and R2) were supplied with synthetic wastewater containing sulfate and ...
Influence of feed time and sulfate load on the organic and sulfate removal in an ASBR
(ELSEVIER SCI LTD, 2010)
The removal of sulfate and organic matter was assessed in an ASBR, which treated wastewater containing 500 mg COD L(-1) (3 g COD L(-1) d(-1)) in 8 h-cycles at 30 degrees C. The wastewater was enriched with sulfate at ...
Anaerobic treatment of sulfate-rich wastewater in an anaerobic sequential batch reactor (AnSBR) using butanol as the carbon source
(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2011)
Biological sulfate reduction was studied in a laboratory-scale anaerobic sequential batch reactor (14 L) containing mineral coal for biomass attachment. The reactor was fed industrial wastewater with increasingly high ...
Selection of sulfur oxidizing bacterium for sulfide removal in sulfate rich wastewater to enhance biogas production
(Pontificia Universidad Católica de Valparaíso, 2008)
Temperature and feed strategy effects on sulfate and organic matter removal in an AnSBB
(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2011)
The objective of this work was to analyze the interaction effects between temperature, feed strategy and COD/[SO(4)(2-)] levels, maintaining the same ratio, on sulfate and organic matter removal efficiency from a synthetic ...
The treatment of sulfate-rich wastewater using an anaerobic sequencing batch biofilm pilot-scale reactor
(ELSEVIER SCIENCE BV, 2009)
This paper presents the results from 92 cycles of an anaerobic sequencing batch biofilm reactor containing biomass immobilized on inert support (mineral coal) applied for the treatment of an industrial wastewater containing ...
Characterization of immobilized biomass by amplified rDNA restriction analysis (ARDRA) in an anaerobic sequencing-batch biofilm reactor (ASBBR) for the treatment of industrial wastewater
(Brazilian Archives of Biology and Technology, 2012)
The performance of an anaerobic sequencing-batch biofilm reactor (ASBBR- laboratory scale- 14L )containing biomass immobilized on coal was evaluated for the removal of elevated concentrations of sulfate (between 200 and ...
