| Abstract: | Biodegradation of organics in fluidized bed reactors was studied experimentally. Both single-substrate and mixed-substrate systems were considered. With the use of a previously developed biofilm model, parameters pertinent to the degradation of mixed-substrate systems and their single substrate system counterparts were evaluated and compared. Two approaches attempted to predict the degradation of a mixed-substrate system. One assumed independent biodegradaion and diffusion of individual substrates while the other used a lumped concentration approach. The latter approach was found to give better agreement with experiments than the former. |
