Sulfide‐oxidizing bacteria: their role during air‐stripping
Biological oxidation of sulfide enhances the removal of sulfide from groundwater by diffused aeration.
Air‐stripping, used to remove hydrogen sulfide naturally present in many groundwater supplies, commonly causes sulfideoxidizing bacteria to proliferate. The role of sulfide‐oxidizing bacteria during air‐stripping was investigated in a diffused‐air pilot reactor modeled after an existing treatment facility. Visible bacterial filaments and biofilm developed within a few days and increased both the sulfide removed from and turbidity in the effluent. Total sulfide, dissolved oxygen, pH, and electrode potential were monitored at eight locations in the reactor to characterize the process.
