About this book
The most effective way to understand dynamic environmental processes lies through the disciplines of dynamic modelling and computer simulation. This book describes the many environmental processes that lend themselves to modelling, and provides simulation examples, both in the book and on an accompanying diskette in the simulation language ISIM, which can be used on any DOS personal computer.
Contents
Part 1 Modelling principles: the role of modelling in environmental technology; general aspects of the modelling approach; model classification; general modelling procedure; simulation tools; ISIM; introductory ISIM example - WASTE; formulation of dynamic balance equations; chemical and biological reaction systems; modelling of bioreactor systems; mass transfer theory; diffusion and biological reaction in solid phase biosystems; process control; optimization, parameter estimation and sensitivity. Part 2 Environmental bioprocess descriptions: wastewater treatment processes; primary treatment processes; secondary treatment processes; tertiary treatment processes; water pollution modelling; solid waste treatment and disposal; references for chapters 1 and 2; recommended textbooks and references for further reading. Part 3 Simulation examples of environmental bioprocesses: introductory examples; basic biological reactor examples; activated sludge wastewater treatment processes; fixed film reactors for wastewater treatment; nitrification of wastewater; primary treatment of wastewater; tertiary water treatment processes; sludge disposal and processing; biodegradation processes; anaerobic digestion processes; anaerobic fixed film processes; microbial interaction kinetics; ecological population studies; river and stream modelling; lake and reservoir modelling; land pollution modelling; miscellaneous examples. Appendix - instructions for using ISIM.
