ABSTRACT
There has been a growing interest in the application of biological fixed-film (attached growth) processes, such as the rotating biological contactor (RBC), for the aerobic treatment of industrial wastewaters. Stability and long retention of microorganisms in the RBC process proved to be advantageous. 1 Although the RBC process has been extensively examined for municipal wastewater treatment applications, 2 its performance during the treatment of high-strength industrial wastewaters has not received equal attention. Process kinetics have yet to be determined under conditions of high influent organic concentrations and long retention times encountered in such situations in order to adequately design the RBC process.
