4 The Nutrient Roadmap. Water Environment Federation
(2015), WEF Press, 601 Wythe Street, Alexandria, VA
22314-1994, USA, 184 pp., softcover, $105., ISBN:
978-1-57278-314-0
This is a reference book prepared by the Nutrient Roadmap Task Force of the Water
Environment Federation (WEF) for guiding decision-makers to retool their wastewater treatment plants (WWTPs) into water resource recovery facilities (WRRFs)
that not only produce clean plant effluent but also recover phosphorus and nitrogen
for reuse in an environmentally conserving manner. The reviewers give credits to
Dr. Samuel S. Jeyanayagam, Task Force Chair, and his 83 task force members for
publication of this nutrient removal/recovery roadmap [4].
The book has seven chapters covering the important subjects of nutrient roadmap
purpose, nutrient removal/recovery drivers and trends, staff education, financing,
planning, the US regulatory requirements, receiving water environment, WRRF
existing performance, nutrient sources and characteristics, process models and
modifications/additions, effluent limits, permit conditions, water-nutrient-energy
nexus, nutrient removal/recovery systems, nonpoint source control technologies,
point source control technologies, mainstream treatment, sidestream treatment, biosolids management and recovery options, water recycle, other resources recovery,
alternatives evaluation steps, risks identification and management, and case studies.
Although all seven chapters are equally important, Chapter 4 (“Resource Recovery”), Chapter 5 (“Alternatives Evaluation”), and Chapter 7 (“Case Studies”) actually show the readers what the nutrient removal/recovery roadmap is. An
experienced environmental engineer may adopt the roadmap for determination of a
feasible nutrient removal/recovery system for his/her clients.
It should be noted, however, the book is a timely, high-level overview document
that provides useful guidance to only experienced decision-makers and other knowable parties, such as regulatory managers, public health professionals, professors,
and researchers. For an in-depth technological discourse, the readers are directed to
other publications, including the USEPA manuals and the WEF Manuals of Practice
and special publications listed at the end of each chapter.
For international adoption and distribution, the book has adopted both the US
customary units and the international metric units. Further improvements of the book
may include (1) addition of a glossary of terms section and (2) inclusion of some
international regulatory requirements for nutrient removal/recovery. Overall it is a
five-star, excellent reference book.
