When one considers the relative simplicity of the design analysis above with the complicated nature of the physical and biological processes involved in the operation of an activated sludge facility, it is remarkable that equations (13.3.1) to (13.3.14) provide a reasonable description of the steady-state behavior of the concentrations of the limiting substrate and the lumped microorganisms when one has access to the corresponding kinetic parameters (iVax> and Fx/s) obtained using... 

Activated sludge wastewater treatment is the most common example of an aerobic suspended culture process. Many factors must be considered in Ac design and operation of an activated sludge wastewater treatment system. These include parameters involved with the process modeling and kinetics. The microbiology of the system must be considered. In addition to BOD removal, phosphorus and nitrogen removal must also be taken into account. Oxygen transfer and solids separation are important. Industrial wastes and the fates and effects of industrial chemicals (xenobiotics) must also be considered.
