Actual coal gasification wastewaters have been treated successfully using a fixed-film, fluidized-bed bioreactor. Phenol removal exceeded 99% and COD removal was typically 75 to 85% for 50% strength wastewater. Batch kinetic tests showed potential for further improvement in bioreactor kinetics. A bioreactor model has been developed to guide further process development. A preliminary economic evaluation of a commercial scale process indicated that there is potential for as much as a 50% reduction in both capital and operating costs by use of fluidized-bed bioreactor technology rather than conventional activated-sludge technology. 9 references, 8 figures, 10 tables.
