MODELING ASPECTS OF ACTIVATED SLUDGE PROCESSE PART 2, Mathem

Abstract
Mathematical process modeling and biokinetics of activated sludge process
were reviewed considering different types of models. It has been evaluated the task
group models of ASM1, and 2, and 3 versioned by Henze et al considering the
conditions of each model and the different processes of which every model consists. It
is revealed that ASM1 contains some defects avoided in ASM3. Relied on
homogeneity, Models can be classified into homogenous models characterized by
taking the activated sludge process as one phase. In this type of models, the internal
mass transfer inside the flocs was neglected.. Hence, the kinetic parameter produces
can be considered inaccurate. The other type of models is the heterogeneous model.
This type considers the mass transfer operations in addition to the biochemical
reaction processes; hence, the resulted kinetic parameters can be considered more
accurate than that of homogenous type.
