Kinetic Analysis of Rotating Biological Contactors Treating High Strength Wastes

The type of kinetics used to describe biological reaction rates within biofilms include both ~ o n o d l ' and zero order kinetics." Results obtained by shiehI2 indicate that the observed reaction rate in a zero order biofilm process is first order if external mass transfer is rate-limiting. The reaction order changes from first order to half order when internal mass transfer becomes predominant. A comprehensive review of biofilm kinetics has been presented by ~arremoes."
