Environmental Transport Processes

A unique approach to the challenges of complex environmental systems Environmental Transport Processes, Second Edition provides much-needed guidance on mass transfer principles in environmental engineering. It focuses on working with uncontrolled conditions involving biological and physical systems, offering examples from diverse fields, including mass transport, kinetics, wastewater treatment, and unit processes. This new edition is fully revised and updated, incorporating modern approaches and practice problems at the end of chapters, making the Second Edition more concise, accessible, and easy to use. The book discusses the fundamentals of transport processes occurring in natural environments, with special emphasis on working at the biological?physical interface. It considers transport and kinetics in terms of systems that involve microorganisms, along with in-depth coverage of particles, size spectra, and calculations for particles that can be considered either spheres or fractals. The book's treatment of particles as fractals is especially unique and the Second Edition includes a new section on exoelectrogenic biofilms. It also addresses dispersion in natural and engineered systems unlike any other book on the subject. Readers will learn to tackle with confidence complex environmental systems and make transport calculations in heterogeneous environments with mixtures of chemicals.Content: Chapter 1 Introduction (pages 1–17): Chapter 2 Equilibrium Calculations (pages 18–42): Chapter 3 Diffusive Transport (pages 43–78): Chapter 4 The Constitutive Transport Equation (pages 79–94): Chapter 5 Concentration Profiles and Chemical Fluxes (pages 95–119): Chapter 6 Mass Transport Correlations: From Theory to Empiricism (pages 120–139): Chapter 7 Transport in Sheared Reactors (pages 140–166): Chapter 8 Suspended Unattached and Aggregated Microorganisms (pages 167–193): Chapter 9 Biofilms (pages 194–231): Chapter 10 Disperson (pages 232–263): Chapter 11 Rivers, Lakes, and Oceans (pages 264–291): Chapter 12 Chemical Transport in Porous Media (pages 292–330): Chapter 13 Particles and Fractals (pages 331–361): Chapter 14 Coagulation in Natural and Engineered Systems (pages 362–407): Chapter 15 Particle Transport in Porous Media (pages 408–444): "Developed as a reference for transport phenomena courses, this completely revised second edition of Environmental Transport Processes provides a readable and approachable treatment of environmental systems. The text features a unique combination of material from different fields (mass transport, kinetics, wastewater treatment, unit processes) and includes pertinent literature not available in any other texts. Rich with examples and problems to help reinforce students? learning, the updated edition addresses new and emerging topics, such as non-aqueous phase liquids (NAPLs), the subject of aggregates, and biofilm kinetic models merged with mass transport concepts"-- "The second edition of Environmental Transport Processes has the same general format as the first edition. The book is intended to serve as a reference for a course on transport phenomena. The book uses many examples and provides a large number of problems that students can use to learn the material. Most of the material from the first edition has stayed relevant, however some sections of the book are now out of date and require to be addressed using more modern approaches"-- This book provides practicing engineers and graduate students with a clear, comprehensive introduction to transport processes in environmental systems. Structured to suit a one-semester, introductory course on the subject, it begins with the basics of molecular diffusion and chemical partitioning and then progresses to more advanced topics including dispersion, particle transport, fractals and biofilms. Throughout, the author places an equal emphasis on both engineered and natural systems. Each chapter draws on realistic examples and problems to reinforce important concepts. Environmental Transport Processes is an ideal first textbook for environmental engineering students who have never studied mass transport, as well as undergraduate and graduate chemical engineering students with little or no experience in environmental topics. It is also a valuable working resource for professionals in those fields, and all researchers interested in transport processes.
