OMAHA, NEB. — HDR’s Joe Cleary, a senior vice president and section manager of engineering design services in the Mahwah, N.J., office, co-authored a newly released book, "Activated Sludge Technologies for Treating Industrial Wastewaters — Design and Troubleshooting." The book is for students, plant operators, and engineers seeking knowledge and case studies on recent developments in activated sludge biological treatment. The timing of the book’s publication is strategically aligned with the 2013 100-year anniversary of the activated sludge process, a major milestone for treatment of wastewater. Though the process has evolved over the past century, the same basic principles remain intact and are reviewed in the book.

Cleary’s book addresses topics such as the evolution of the activated sludge process, more stringent effluent permit limits, advancements in treatability testing and process modeling tools, microconstituents, sustainability goals for water and energy, and the impact of frac water from the development of shale gas plays.

Cleary has 40 years of experience providing environmental engineering consulting services to both private and public sector clients in the United States, Puerto Rico, Mexico, South America and Europe. He has been active with the Water Environment Federation (WEF) and has chaired or served on a number of committees, chaired conferences and workshops, and participated in webinars and technical practice updates. Last year he received the prestigious WEF Industrial Water Quality Lifetime Achievement Award at WEFTEC 2012.

"Activated Sludge Technologies for Treating Industrial Wastewaters" is available for purchase through the publisher at and through Amazon.
