Anaerobic fluidized-bed GAC reactors have been proven successful for the treatment of biologically inhibiting wastewaters such as coal conversion wastewaters. Adsorption on granular activated carbon (GAC) represents a viable strategy for the removal of these inhibitory compounds. Partial replacement of the carbon bed is then necessary to maintain the concentration of inhibitory compounds below threshold levels. The cost of the GAC replacement thus represents a major operating cost of the system. Objectives of this research are to determine, using experimental and modeling strategies, the effects of hydraulic detention time and the schedule of GAC replacement on the performance of fluidized bed GAC anaerobic reactors during the treatment of coal conversion wastewater. This objective is realized by the following activities: (a) Operation of two expanded-bed GAC anaerobic reactors at empty-bed hydraulic detention times of 1.0 and 0.5 days. Wastewater includes phenol, acetic acid and o-cresol as model compounds of a real coal conversion wastewater. (b) Development of a mathematical model. (c) The calibrated model will be used to analyze a vast volume of experimental data on the treatment of coal gasification wastewater and refinery sour water stripper bottoms. 1 ref., 4 figs., 2 tabs.
