Sewer Processes ― Microbial and Chemical Process Engineering of Sewer Networks

Since the first edition was published over a decade ago, advancements have been made in the design, operation, and maintenance of sewer systems, and new problems have emerged. For example, sewer processes are now integrated in computer models, and simultaneously, odor and corrosion problems caused by hydrogen sulfide and other volatile organic compounds, as well as other potential health issues, have caused environmental concerns to rise.

Reflecting the most current developments, Sewer Processes: Microbial and Chemical Process Engineering of Sewer Networks, Second Edition, offers the reader updated and valuable information on the sewer as a chemical and biological reactor. It focuses on how to predict critical impacts and control adverse effects. It also provides an integrated description of sewer processes in modeling terms. This second edition is full of illustrative examples and figures, includes revisions of chapters from the previous edition, adds three new chapters, and presents extensive study questions.

• Presents new modeling tools for the design and operation of sewer networks
• Establishes sewer processes as a key element in preserving water quality
• Includes greatly expanded coverage of odor formation and prediction
• Details the WATS sewer process model
• Highlights the importance of aerobic, anoxic, and anaerobic processes

Sewer Processes: Microbial and Chemical Process Engineering of Sewer Networks, Second Edition, provides a basis for up-to-date understanding and modeling of sewer microbial and chemical processes and demonstrates how this knowledge can be applied for the design, operation, and the maintenance of wastewater collection systems. The authors add chemical and microbial dimensions to the design and management of sewer networks with an overall aim of improved sustainability for the system itself and the surrounding environment.

Thorkild Hvitved-Jacobsen, MSc, is professor emeritus at Aalborg University, Denmark. In 2008, he retired from his position as professor of environmental engineering at the Section of Environmental Engineering, Aalborg University, Denmark. His primary research and professional activities concern environmental process engineering of the wastewater collection and treatment systems, including process engineering and pollution related to urban drainage and road runoff. His research has resulted in more than 320 scientific publications in primarily international journals and proceedings. He has authored and coauthored a number of books published in the United Kingdom, the United States, and Japan.

Jes Vollertsen, PhD, is a professor of environmental engineering at the Section of Water and Soil, Department of Civil Engineering, Aalborg University, Denmark. His research interests are urban storm water and wastewater technology, where he combines experimental work on bench scale with pilot-scale studies and field studies. He integrates the gained knowledge on conveyance systems and systems for wastewater and storm water management by numerical modeling of the processes. He is an experienced consultant for private firms and municipalities as well as on litigation support. He is a reviewer for a national research committee in relation to environmental engineering.

Asbjorn Haaning Nielsen, PhD, is an associate professor of environmental engineering at the Section of Water and Soil, Department of Civil Engineering, Aalborg University, Denmark. His research and teaching has primarily been devoted to wastewater process engineering of sewer systems and process engineering of combined sewer overflows and storm water runoff from urban areas and highways. He has extensive experience with chemical analyses of complex environmental samples, particularly relating to the composition of wastewater and sewer gas. He is a committee member of the Danish National Committee for the IWA.
