ABSTRACT:
A biological process is described for caustic waste streams containing inorganic sulfides to effect neutralization of the caustic and, oxidation of sulfides to sulfate. The process is based on the contact of these caustic streams with mixed, fiocculated cultures of a sulfide-oxidizing bacterium from the genus Thiobacillus and various heterotrophs. The process may also degrade any organic components present in the waste stream.
