Abstract
: Biogas methane requires appropriate filtration to minimize the corrosively effects of sulfide on the general infrastructure. In this work, a lab scale bioreactor inoculated with photosynthetic green sulfur-oxidizing bacteria was evaluated to its potential to remove headspace sulfide. Anaerobic green sulfur-oxidizing bacteria were isolated from a local swine waste pit and induced to grow over time on a sulfide-rich culturing media. 1-L glass batch reactors were used to mimic the removal of hydrogen sulfide from biogas stream. A negative control inoculated with non-sulfur oxidizing bacteria consortium was used to discern abiotic losses. Removal efficiencies of 100 to 95% were obtained for sulfide concentrations ranging from 610 to 1,200 ppmV, respectively. Interestingly, the prompt sulfide removal rate observed (i.e. < 5 minutes) encouraged further expectations of engineered biofiltering systems to remove sulfide from biogas stream at field scale.
