The theory, design, construction, and operation of microbial fuel cells Microbial fuel cells (MFCs), devices in which bacteria create electrical power by oxidizing simple compounds such as glucose or complex organic matter in wastewater, represent a new and promising approach for generating power. Not only do MFCs clean wastewater, but they also convert organics in these wastewaters into usable energy. Given the world's limited supply of fossil fuels and fossil fuels' impact on climate change, MFC technology's ability to create renewable, carbon-neutral energy has generated tremendous interest around the world. This timely book is the first dedicated to MFCs. It not only serves as an introduction to the theory underlying the development and functioning of MFCs, it also serves as a manual for ongoing research. In addition, author Bruce Logan, a leading pioneer in MFC research and development, provides practical guidance for the effective design and operation of MFCs based on his own firsthand experience. This reference covers everything you need to fully understand MFCs, including: * Key topics such as voltage and power generation, MFC materials and architecture, mass transfer to bacteria and biofilms, bioreactor design, and fundamentals of electron transfer * Applications across a wide variety of scales, from power generation in the laboratory to approaches for using MFCs for wastewater treatment * The role of MFCs in the climate change debate * Detailed illustrations of bacterial and electrochemical concepts * Charts, graphs, and tables summarizing key design and operation variables * Practice problems and step-by-step examples Microbial Fuel Cells, with its easy-to-follow explanations, is recommended as both a textbook for students and professionals interested in entering the field and as a complete reference for more experienced practitioners.

Provides an accessible and relatable approach for understanding how much energy we use in our day-to-day lives Daily Energy Use and Carbon Emissions enables readers to directly evaluate their energy use, estimate the resulting carbon emissions, and use the information to better appreciate and address the impact their activities have on climate change. Using quantities and terms rooted in everyday life, this easy-to-understand textbook helps readers determine the energy they consume driving a car, preparing a meal, charging electronic devices, heating and cooling a house or apartment, and more. Throughout the text, clear explanations, accurate information, and numerous real-world examples help readers to answer key energy questions such as: How much energy does your house use in a month? What impact will turning off lightbulbs in your home have on energy conservation? Which car emits more CO2 into the atmosphere per mile, a 50 MPG gasoline car or a 100 MPG equivalent electric car? Demonstrating the relation between daily energy use, carbon emissions, and everyday activities in a new way, this innovative textbook: Examines daily activities within the context of the basic needs: energy, food, air, and water Covers topics such as daily water use, renewable energy, water and energy sources, transportation, concrete and steel, and carbon capture and storage Includes discussion of energy and CO2 emissions relative to infrastructure and population growth Provides supplemental teaching material including PowerPoint slides, illustrative examples, homework assignments, discussion questions, and classroom quizzes with answers Daily Energy Use and Carbon Emissions: Fundamentals and Applications for Students and Professionals is a perfect textbook for students and instructors in Environmental Engineering programs, and an essential read for those pursuing careers in areas related to energy, environment, and climate change.

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.
