The 2nd edition of Fundamentals of Wastewater Treatment and Design introduces readers to the fundamental concepts of wastewater treatment, followed by engineering design of unit processes for sustainable treatment of municipal wastewater and resource recovery. It has been completely updated with new chapters to reflect current advances in design, resource recovery practices and research. Another highlight is the addition of the last chapter, which provides a culminating design experience of both urban and rural wastewater treatment systems.

Filling the need for a textbook focused on wastewater, it covers history, current practices, emerging concerns, future directions and pertinent regulations that have shaped the objectives of this important area of engineering. Basic principles of reaction kinetics, reactor design and environmental microbiology are introduced along with natural purification processes. It also details the design of unit processes for primary, secondary and advanced treatment, as well as solids processing and removal. Recovery of water, energy and nutrients are explained with the help of process concepts and design applications.

This textbook is designed for undergraduate and graduate students who have some knowledge of environmental chemistry and fluid mechanics. Professionals in the wastewater industry will also find this a handy reference.

Building on the success of the second edition, this truly accessible textbook comprehensively covers the 2008 AS and A2 level Physics specifications for all the main UK exam boards.The book also has a companion website which is free to book users providing extra resources.

Written by authors with many years' experience of teaching, examining and writing, this is an ideal resource for class or independent study.

The book includes the following features:

* How Science Works feature boxes focus on this key element of the new specifications.

* Stretch and Challenge boxes challenge more able students, enabling them to achieve the highest grades.

* Science in Context boxes encourage students to relate their learning to the world around them.

* Summaries at the end of every chapter help students with revision.

* Test Yourself questions throughout the text enable students to monitor their own progress in preparation for their exams.

* Remember This boxes highlight the key facts.

The website provides the following additional resources:

* Practice questions (and answers) allow students to test their understanding of the material just covered.

* How Science Works assignments allow students to prepare for the How Science Works element of the new AS and A2 Physics exams.

David Grace has been teaching Physics and Electronics for 36 years. After 17 years in a London comprehensive, he has been Head of Science at Ysgol Y Preseli in Pembrokeshire since 1988. During that time he has taught Nuffield A level and Advancing Physics and was part of the team that revised the Nuffield course in the early eighties and had a small hand in the A2 section of Advancing Physics. He has taken a particular interest in communications technology, contributing to various education resources. He became a Teacher Fellow in Engineering in 1983 after spending a term working on the first undersea optical fibre system. David has been an A level examiner for OCR for over thirty years as well as working for other boards as an examiner and moderator in GCSE Science and Electronics. He is currently the Teacher Network Co-ordinator for the Institute of Physics covering West Wales.

David Lovett was a lecturer in Physics for nearly forty years at Essex University and is now visiting teaching fellow and director of the Physics Centre. He is also an associate lecturer with the Open University. For many years he was an awarder and moderator with the Oxford and Cambridge Examination Board. He is the author of a number of books and has published a wide range of research papers.

Ken Dobson taught for Science for 30 years, 26 of them as Head of department. He has also been a member of various panels, committees and advisory groups for science education at a national level, and especially for the Institute of Physics (UK). His positions are too numerous to list but include National Director of Suffolk Science which rapidly became the largest new curriculum development in the UK for GCSE, Reviser for Physics at Ordinary Level for the Northern Joint Examination Board and Chief Examiner with the Oxford and Cambridge Examining Board for Nuffield Advanced Physics, eventually becoming Chairman of Awarders. Ken has also written numerous Physics titles which have had considerable success both in the UK and overseas. In 2000, he was made an Honorary Life Member of the Association for Science Education (UK) for his contributions to science education in East Anglia and nationally. He was then awarded the Bragg Medal and Prize by the Institute of Physics in 2005 for important contributions to assessment and the development of original curriculum material in Physics education, nationally and internationally.
