Is there any truth to the rumor that the additon of nano silcate to the FGD wastewater stream will precipitate selenate and selenite?

that sounds almost too good to be true- I thnk it depends on the particular form of Se that is present in the FGD purge.
Other means being studied, besides bioreactors, is a trickle filter ( packed bed) of AC activated carbon or , better yet, sawdust or powdered torrefied wood dust.
