ABSTRACT:
Anaerobic bacteria, e.g., of the Desulfovibrio family, are added to oil shale retort water producing an increase in cell biomass and reducing sulfate ions present to sulfide. The cell biomass is aggregated into a flocculent mass and removed. The sulfide can be oxidized and recycled to neutralize the retort water. Oxidation of sulfide to sulfate can be accomplished by addition of aerobic bacteria, e.g., of the Thiobacillus family.
