The purpose of this paper is to present a logical approach to develop mathematical models for assessing the fixed-film buildup and sloughings in a biological waste treatment process and their resultant impacts on the rate of waste stabilization. Careful experimental testings are now being conducted at the University of Missouri-Rolla to generate pertinent parameters associated with modeling. Besides, these testings will also be used to verify the validity of the proposed models. It is hoped that with a better understanding of the fixed-film system, future designs of RBC and aerobic fluidized-bed biological reactor can be optimized by eliminating the oxygen availability as the most common rate-limiting factor. This would result in a significant reduction of the reaction time requirement, thus achieving a corresponding capital saving associated with the tankage construction.
