MODELING ASPECTS OF ACTIVATED SLUDGE PROCESSES PART 1, PROCE

Abstract
Process modeling of activated sludge flocculation and sedimentation
reviews consider the activated sludge floc characteristics such as: morphology
viable and non-viable cell ratio density and water content, bioflocculation and its
kinetics were studied considering the characteristics of bioflocculation and
explaining theory of Divalent Cation Bridging which describes the major role of
cations in bioflocculation.
Activated sludge flocculation process modeling was studied considering
mass transfer limitations from Clifft and Andrew, 1981, Benefild and Molz 1983
passing Henze 1987, until Tyagi 1996 and G. Ibrahim et al. 2002. Models of
aggregation and breakage of flocs were studied by Spicer and Pratsinis 1996,and
Biggs 2002.
