Abstract
It has been demonstrated that viable cells of the chemoautotroph and facultative anaerobeThiobacillus denitrificans can be used to remove soluble sulfides from sour water with anaerobic oxidation to sulfate. A packed bed of immobilized T.denitrificans was capable of removing all traces of sulfide from an aqueous feed stream containing 26 ppm sulfide during a continuous 12 day test. Calcium carbonate provided buffering capacity and generated Ca+2 internal to alginate beads to maintain structural integrity during extended periods of operation.
