ABSTRACT:
A method for treating an aqueous stream containing a water-soluble, inorganic sulfide compound wherein the stream is contacted with oxygen at a pH in the range of less than about 12 and an oxygen to sulfur molar ratio greater than about 5 with an oxidizing catalyst at oxidation conditions selected to provide a high conversion of the inorganic sulfide compound to sulfate to thereby produce a substantially sulfide-free treated aqueous product stream.
