Methods for removing selenium from aqueous systems Moore, Lucas; Mahmoudkhani, Amir
Abstract
Selenium is among the list of oxyanions that lead to contamination in mining aqueous waste streams. Though the elemental forms are toxic, the aqueous oxyanions are more so. The most common forms of selenium released during mining processes are the aqueous forms, selenite and selenates. The common treatment technologies to date can be summed up in these major categories: media filtration, chemical treatment, and biomediated removal. These methods can often involve many expensive processing steps that may also be limited by variables such as total dissolved solids, presence of other ions, and ability to maintain microbial growth. We have developed an innovative chemical technology that can successfully reduce selenates to a level below the EPA recommendations. This new technology offers a unique and viable solution which is transparent to the above mentioned limitations. [All papers were considered for technical and language appropriateness by the organizing committee.]

Selenium is among the list of oxyanions that lead to contamination in mining aqueous waste streams. Though
the elemental forms are toxic, the aqueous oxyanions are more so. The most common forms of selenium
released during mining processes are the aqueous forms, selenite and selenates. The common treatment
technologies to date can be summed up in these major categories: media filtration, chemical treatment, and
biomediated removal. These methods can often involve many expensive processing steps that may also be
limited by variables such as total dissolved solids, presence of other ions, and ability to maintain microbial
growth. We have developed an innovative chemical technology that can successfully reduce selenates to a level
below the EPA recommendations. This new technology offers a unique and viable solution which is transparent
to the above mentioned limitations. [All papers were considered for technical and language appropriateness by the organizing committee.]
