Abstract:
A novel method for treating sulfide-containing wastewater is described which involves treating sulfide-laden biogas produced in a bioreactor in a sulfide oxidizing unit (SOU). Oxidation in the SOU is monitored by an oxidation reduction potential (ORP) probe which minimizes the input of air/oxygen to produce elemental sulfur without significant production of sulfate.
