Design of a bioprocess for metal and sulfate removal from acid mine drainage
(Elsevier B.V., 2018)
© 2018 The high levels of sulfate and the metals in acid mine drainages generate important environmental problems. This paper describes the synergistic combination of a biosorption process and a new sulfate removal process. ...
A Kinetic Analysis of Microbial Sulfate Reduction in an Upflow Packed-Bed Anaerobic Bioreactor
The effects of initial sulfate concentration on anaerobic sulfate reduction and sulfide generation kinetics were investigated in an up-flow bioreactor, using a consortium of sulfate-reducing bacteria (SRB) from water ...
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 ...
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
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 ...
A kinetic study on bacterial sulfate reduction
The activity of anaerobic sulfate reduction was studied using sulfate-reducing bacteria isolated from the water produced from a Brazilian oil reservoir. The effects of the initial sulfate concentration on the anaerobic ...
