Abstract
The U.S. Bureau of Mines is conducting laboratory research on bacterial removal of selenium from wastewaters. A mixed bacterial culture has been removing up to 96 pct of the selenium from agricultural drainage waters in a small-scale, continuous, plug-flow reactor for 1 yr; selenium removal is correlated to changes in the bacterial cultures. Data are presented on the complex interrelationships between the reduction of selenate and other compounds such as nitrate, phosphate, and sulfate. Bacterial respiration studies, results from x-ray diffraction studies, and scanning electron photomicrographs of the product are presented to further elucidate the mechanisms of selenium removal. Results also show that bacteria isolated from agricultural drainage waters can be applied successfully to remove selenium from mine tailings pond water.
