Abstract
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 ce Ltd. All rights reserved.
