Copper, nickel, zinc and lead were added to the feed of the methanogenic stage of a two-phase thermophilic anaerobic digester, which had an overall hydraulic retention time of 10 5 h. Each metal was added for a period of 30 h. A period of 7 days was used between the metal dosing as a recovery phase. All the metals caused a reduction in the chemical oxygen demand removal which was reversed when...
A two-phase, thermophilic anaerobic reactor was operated with a starch-based feed. Copper, zinc, nickel and lead (3 mM) were individually added to the feed each for a period of 30 h. The results were analysed to determine the extent of metal binding in the acidogenic, first-stage reactor and the degree of protection that this afforded to the traditionally more sensitive methanogenic phase. The...
