WebMultiple steady states and falsified kinetics can negatively affect a biofilter and the experimental determination of kinetic parameters, respectively. Implications: The occurrence of multiple steady states in a V OC treating biofilm, shows the significant impact of degradation kinetics and diffusion limita tion on the biofilm behavior. WebThe book thoroughly prepares undergraduates to apply chemical reaction kinetics and physics to the design of chemical reactors. And four advanced chapters address graduate-level topics, including effectiveness factors. To support the field’s growing emphasis on chemical reactor safety, each chapter now ends with a practical safety lesson.
