Abstract
A process for simultaneous removal of hydrogen sulfide (HS) and heavy metals from mixture includes charging a contaminated aqueous composition containing heavy metal ions to a reactor. The process also includes passing a HS-containing gas composition via a plurality of gas spargers through the contaminated aqueous composition present in the reactor to form a HS-containing contaminated aqueous composition and a purified gas composition. The process further includes reacting the HS from the HS-containing contaminated aqueous composition with the heavy metal ions in the HS-containing contaminated aqueous composition to form a metal sulfide precipitate in a metal-sulfide-containing contaminated aqueous composition. In addition, the process includes at least partially introducing the metal-sulfide-containing contaminated aqueous composition to a solid-liquid separator and removing the metal sulfide precipitate from the metal-sulfide-containing contaminated aqueous composition to form a purified aqueous composition.
