The selected examples include steady and unsteady state analyses using algebraic and differential equations solved by analytical trial and error and numerical methods. Computer implementation of the mathematical models for the above are presented. The rationale for selecting appropriate software packages for modeling the different problems and their merits and demerits are discussed. INTRODUCTION This chapter will serve as the capstone chapter for engineered systems in that the principles and philosophies covered in the previous chapters are integrated and applied in the modeling of engineered environmental systems. Engineered systems involving steady and unsteady conditions are modeled applying the general theories presented in Chapter 4 to various reactor configurations discussed in Chapter 5 utilizing the software packages identified in Chapter 7. The first example illustrates the entire modeling process from model development to computer implementation to calibration to validation. The rest of the examples illustrate the model development and computer implementation procedures. MODELING EXAMPLE TRANSIENTS IN SEQUENCING BATCH REACTORS This example is based on a treatability study on a high-strength waste from a soft drink bottling facility reported by Laughlin et al. 1999 . Due to the 2002 by CRC Press LLC high variation in waste flow rate and its constituents a sequencing batch reactor SBR configuration was chosen to pretreat this waste prior to discharge into the city sewers. This example illustrates the modeling of the SBR process to predict the temporal variation of substrate dissolved oxygen and biomass growth during the fill and react phases of the process. Specifically the objective of the original study was to investigate whether the bioprocess would be limited by .
