Abstract : Tests results demonstrated the effectiveness of the two-stage anaerobic filters in the treatment of phenolic wastewaters. Results indicated that the anaerobic process employed in this study can be used for the treatment of phenol -bearing wastewater. Whereas the maximum concentration of phenol that can be treated with the anaerobic process is still under evaluation, the optimum concentration of phenol was found to be 1600 mg/l. This is 4 times higher than that reported in the literature. A maximum loading of 2 Kg phenol/cu m 3 day (i.e., 4.76 Kg COD/cu m 3 day) was accomplished with a 94 percent conversion of both COD and TOC. At the maximum loading studied (2 Kg phenol/cu m 3 day) a 99.7 percent conversion of phenol was obtained with the reactors connected in reverse order, i.e., fluidized carbon column followed by fixed Raschig ring bed. By reversing the sequence of reactor order, i.e., fluidized column followed by fixed bed, it resulted in an effluent having low suspended solids concentrations.
