Sewer Processes: Microbial and Chemical Process Engineering of Sewer Networks, Second Edition, Edition 2

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
