Anaerobic treatment of gasifier effluents. Final report
An evaluation of the technical feasibility of using the completely mixed, expanded-bed granular activated carbon (GAC) anaerobic filter for the treatment of real and synthetic coal gasification wastewaters is presented. The treatment of both coal gasification wastewaters revealed that inhibition to the biological processes occurred after the breakthrough of some of the compounds present in the wastewaters. This inhibition was controlled through the use of a carbon replacement schedule. A fraction of the GAC medium was periodically withdrawn from the anaerobic filter and replaced with virgin activated carbon. This strategy appeared to be effective in maintaining the effluent levels of the toxic compounds at below inhibitory concentrations. 54 refs., 30 figs., 20 tabs.
