Microaeration for hydrogen sulfide removal during anaerobic treatment: a review
High sulfide concentrations in biogas are a major problem associated with the anaerobic treatment of sulfate-rich substrates. It causes the corrosion of concrete and steel, compromises the functions of cogeneration units, produces the emissions of unpleasant odors, and is toxic to humans. Microaeration, i.e. the dosing of small amounts of air (oxygen) into an anaerobic digester, is a highly eff...
متن کاملOptimization of factors affecting on sulfide oxidation from synthetic spent caustic by Haloalkaliphilic Thioalkalivibrio versutus by focus on sodium ion effect: Application of response surface methodology
In the present study, the effects of four factors including initial sulfide concentration (mg l-1 ), agitation speed (rpm), amount of inoculums (%) and sodium concentration (mg l-1) on removal efficiency (%R) and yield of sulfate production by Thioalkalivibrio versutus from synthetic spent caustic were investigated. For this purpose, experiments are designed by design of experiments (DOE) and R...
متن کاملCoupled Anaerobic Baffled Reactor (ABR)/Activated Sludge Treatment of Synthetic Wastewater with High Concentration of Sulfate and COD
A synthetic wastewater with high concentration of sulfate and COD was treated in anaerobic baffled reactor (ABR) coupled with an activated sludge. The work was accomplished in two phases. In the first phase, the concentration of sulfate was kept constant at 500mg/l, but COD concentration was increased from (3000mg/l to 6000mg/l), consequently, COD and sulfate removal in ABR reached to 80% and 9...
متن کاملRemoval of hydrogen sulfide from gas streams using biological processes - A review
Syed, M., Soreanu, G., Falletta, P. and Béland M. 2006. Removal of hydrogen sulfide from gas streams using biological processes A review. Canadian Biosystems Engineering/Le génie des biosystèmes au Canada 48: 2.1 2.14. Hydrogen sulfide (H2S) is a toxic and odorous compound present in biogas produced by the anaerobic digestion of biosolids and other organic materials. Due to its corrosive nature...
متن کاملComplete genome sequence of “Thioalkalivibrio sulfidophilus” HL-EbGr7
"Thioalkalivibrio sulfidophilus" HL-EbGr7 is an obligately chemolithoautotrophic, haloalkaliphilic sulfur-oxidizing bacterium (SOB) belonging to the Gammaproteobacteria. The strain was found to predominate a full-scale bioreactor, removing sulfide from biogas. Here we report the complete genome sequence of strain HL-EbGr7 and its annotation. The genome was sequenced within the Joint Genome Inst...
