Many recent developments in municipal waste water treatment technology
are directed towards biological nutrient removal. Chemical fate model
s which are used to predict the behavior of individual chemicals in wa
ste water treatment plants (WWTPs), have until now not incorporated th
is aspect. In this paper, two modifications to the steady-state non-eq
uilibrium SimpleTreat modeling concept (Struijs et at, 1991; Struijs,
1996) are presented. These focus on an improved description of sludge
recycling, and on the presence of different redox zones in the biologi
cal reactor (aerobic, anoxic, anaerobic). The updated models were appl
ied to three different WWTP designs, and simulation results were compa
red to measured values for the surfactant LAS. (C) 1998 Elsevier Scien
