Transport Modeling for Environmental Engineers and Scientists

Transport Modeling for Environmental Engineers and Scientists, Second Edition, builds on integrated transport courses in chemical engineering curricula, demonstrating the underlying unity of mass and momentum transport processes. It describes how these processes underlie the mechanics common to both pollutant transport and pollution control processes.

THE REVISED AND UPDATED EDITION OF THE ESSENTIAL TEXT ON TRANSPORT MODELING Transport Modeling for Environmental Engineers and Scientists, Second Edition addresses the full range of processes that influence how pollutants move through environmental and chemical separations media. Revised and updated for this new Second Edition, the text offers students, teachers, and professionals an unparalleled resource on this important subject.

This Second Edition:

• Covers the fundamentals of mass and momentum transport processes with an emphasis on aerosol, colloidal, macromolecular, biological, and nanoscale systems

• Presents an environmental focus on sedimentation, coagulation, partitioning, adsorption, fluid mechanics, diffusion, dispersion, chromatography, osmosis/reverse osmosis, filtration, and porous media transport

• Includes chapters on chemical kinetics and reactor design

• Features numerous worked examples and exercises at the end of each chapter

The text's comprehensive approach builds on integrated transport courses in chemical engineering curricula, demonstrating the underlying unity of mass and momentum transport processes, and describing how these underlie pollutant transport, analysis, and control. A key text for understanding the field today, Transport Modeling for Environmental Engineers and Scientists, Second Edition is an essential companion for environmental engineers, civil engineers, chemical engineers, and students and professors in these areas.
