A single, fundamental model of biofilm kinetics is shown to be capable of accurately predicting the performance of large-scale, fixed-film processes for denitrification, methanogenesis, and aerobic oxidation. The reactor configurations are fluidized and fixed-bed filters and a rotating disc. The model, which is based on fundamental and independently obtainable parameters of bacterial kinetics and mass transport for a steady-state biofilm, requires no fitting factors. The biofilm model can help suggest useful processes, indicate when other processes will be unable to fulfill design requirements, and help design pilot and full-scale facilities.
