• Description:
  The U.S. Bureau of Mines Salt Lake City Research Center, is investigating biological decontamination of arsenic-bearing mining and milling waste waters. Research is focusing on bacterial conversion of soluble arsenic complexes to insoluble arsenic sulfide compounds. This report describes initial laboratory results using sulfate-reducing bacteria (SRB) in a 2-stage process. SRB-generated sulfides from the stage-1 bioreactor precipitate arsenic from waste water in the stage-2 treatment reactor. Results are presented on (1) optimizing bacterial sulfide production in the bioreactor, and (2) removing arsenic from samples of industrial waste waters in stage 2. Promising exploratory results may lead to a practical biological process for arsenic removal from contaminated water. [Description provided by NIOSH]
