Evaluation of a comprehensive kinetic model for the activated sludge process


Journal Water Pollution Control Federation 49(7): 1636-1641
Evaluation of a comprehensive kinetic model for the activated sludge process
Results of recent investigations from treating variable strength, multicomponent organic substrates in a mixed microbial culture indicate that effluent substrate concentration is dependent upon influent substrate concentration. Many of the more popular kinetic models probably do not adequately describe the rate of substrate utilization under such conditions. Grau and Dohanyos have proposed a model which appears to fit such experimental data very well. The completely mixed activated sludge process with and without recycle was modeled using the Grau-Dohanyos model in conjunction with growth and material balance equations for each of the specific systems. The model can also be applied to a plug-flow fixed growth system.
