One of the key pillars of the Water Design-Build Council's mission is education, and over the past year, we've produced quite a few new educational documents designed to raise awareness of design-build and alternative project delivery methods in the water and wastewater sector. In addition to our own eductional content, our members produce a variety of materials relating to best practices. This past November, Joe Cleary, a senior vice president and section manager of engineering design services with WDBC member HDR Inc., 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 was 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 like 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.
