Treatment Wetland Processes, Design, and Implementation presents a state-of-the-art coverage of wetlands applied to the treatment of municipal wastewater, industrial wastewater, combined sewer overflows, sludge and other sources. It builds upon the highly acclaimed previous editions of Treatment Wetlands, but includes a wealth of new information, data, concepts and approaches that are in syntony with the new developments in the field.
Focusing on subsurface flow wetlands, the text has been thoroughly revised, fully updated and expanded, including a new and detailed coverage of important treatment wetland variants, such as horizontal flow, vertical flow, French vertical flow, aerated, fill-and-drain, combined sewer overflow and sludge treatment wetlands.
Treatment Wetland Processes, Design, and Implementation contains a carefully planned balance between theory and practice, with a clear and didactic presentation of the main concepts, working principles, expected performance, design criteria, construction aspects, and operational guidelines of treatment wetlands with a worldwide perspective on application. The book is an essential source for novice and experienced professionals, researchers, teachers, and students across the globe.

About the Author :
SCOTT WALLACE
Scott Wallace has spent his career over the last 40 years in the private sector, engineering over 250 projects in 22 countries. He is the co-author of Treatment Wetlands, Second Edition, which has been widely considered the definitive textbook on wetland treatment systems.
Scott publishes extensively, with over 80 scientific papers to date. He has been the inventor of over 12 treatment wetland related patents. He invented the first successful aerated wetland process, Forced Bed Aeration in 1997; led the initial creation of the TAYA fill-and-drain process in 2004 and was a co-inventor of the Rhizosph’air process in 2020. While in Minnesota, Scott developed energy balance methods, using in-situ field measurements for insulating cold-climate treatment wetlands now commonly used in sub-freezing environments worldwide. He is a founding member of Global Wetland Technology (GWT).
Scott earned a BSE degree in Civil Engineering and an MS degree in Environmental Engineering, both from the University of Iowa, USA, with a research focus on soil chemistry. Prior to becoming an engineer, he worked as a wastewater treatment plant operator, bench chemist, and field services technician. He is often engaged in projects from design, pilot testing, construction, and start-up.
JAIME NIVALA
Jaime Nivala is a director of research at INRAE (French National Institute for Agriculture, Food and Environment), in Lyon, France in the research unit REVERSAAL, where she has worked since 2019. Prior to that, she worked for 12 years as a scientist at the Helmholtz Center for Environmental Research in Leipzig, Germany. From 2001–2008, Jaime worked in the private sector for North American Wetland Engineering in Minnesota (USA) first as a part-time intern, then as an entry-level engineer, continuing part-time work while earning her Masters’ degree, and finally as a full-time employee before moving to Europe to pursue a career in academia. Jaime has over 25 years of experience in the treatment wetland field, with a special focus on aerated treatment wetland technology development, optimization, and transfer.
Jaime holds a BS in Civil Engineering (University of Minnesota, USA), an MS in Environmental Engineering (University of Iowa, USA), and PhD in Biosciences (Aarhus University, Denmark). She earned her habilitation (professional dissertation) in the field of Chemistry, Processes, and Environment from INSA Lyon and the University of Claude Bernard Lyon I in 2021. Jaime is active with the International Water Association (IWA) Specialist Group “Wetland Systems for Water Pollution Control”, holding the position of co-chair from 2021–2025, contributing to the IWA Task Group “Mainstreaming Treatment Wetlands” which produced two open-access textbooks in 2017 and 2019, and being an active member of the specialist group since 2004.
GÜNTER LANGERGRABER
Günter Langergraber is Senior Scientist at the Institute of Sanitary Engineering and Water Pollution Control at the University of Natural Resources and Life Sciences Vienna (BOKU University) with more than 25 years' experience in treatment wetland research.
Günter is a specialist for vertical flow wetlands and – as developer of the HYDRUS Wetland Module – for numerical simulation of subsurface flow treatment wetlands. Besides research in treatment wetlands, he is active in the fields of resources-oriented sanitation solutions and nature-based solutions.
Günter holds a PhD in Civil Engineering and Water Management and has habilitation (professional dissertation) in the field of Sanitary Engineering, both from BOKU University. He is active in various positions in the International Water Association (IWA) actively promoting treatment wetland technology. He is also active in standardization agencies related to treatment wetland designs and in activities related to mainstreaming treatment wetland technology all around the world and in particular, the Danube River basin.
PASCAL MOLLE
Pascal Molle is a director of research at INRAE (French National Institute for Agriculture, Food and Environment) in Lyon, France, in the research unit REVERSAAL. He has over 25 years' experience in the field of treatment wetland research.
His research is focused on the development and optimization of treatment wetland processes for a range of influent types (domestic wastewater, sludge, combined sewer overflows) and climate conditions (temperate, tropical, cold). He established and has led a French national group on the assessment of new treatment processes for small communities (www.epnac.fr), engaging all French public institutions involved in sanitation issues.
