Abstract Upflow, anaerobic, fixed-bed, activated charcoal biotreatment columns capable of operating at free cyanide concentrations of {gt}100 mg liter{sup {minus}1} with a hydraulic retention time of {lt}48 h were developed. Methanogenesis was maintained under a variety of feed medium conditions which included ethanol, phenol, or methanol as the primary reduced carbon source. Under optimal conditions, {gt}70% of the inflow free cyanide was removed in the first 30% of the column height. Strongly complexed cyanides were resistant to removal. Ammonia was the nitrogen end product of cyanide transformation. In cell material removed from the charcoal columns, ({sup 14}C) bicarbonate was the major carbon end product of ({sup 14}C) cyanide transformation.
