He is also a Fellow of the Water-Energy Nexus Center at the University of California, Irvine, where he contributes to research and innovation in the field.
Daniel holds a BSc in Civil Engineering from the University of Buenos Aires, an MSc in Environmental Engineering from McMaster University (Canada) and an MSc in Technology Management from the Massachusetts Institute of Technology (MIT). Daniel is a certified Professional Engineer (P.Eng.) in Ontario, Canada. He has co-authored 12 books and over 100 technical articles.
ASESSOR
Prof. Diego Rosso, Ph.D.
Dr. Diego Rosso is an international consultant recognised for his expertise in aeration system diagnostics, energy efficiency, carbon footprint analysis, and wastewater treatment process sustainability. Diego has applied aeration diagnostics, carbon footprint and energy analysis at numerous plants, including aeration system design/upgrade/renovation, facility/process energy audits, energy efficiency and benchmarking of treatment processes, carbon footprint analysis of treatment processes and biosolids disposal options, infrastructure climate.
In addition to conducting hundreds of oxygen transfer tests on activated sludge aeration systems and aerobic digesters, Diego conducted the first aeration efficiency investigations on biological aerated filters, integrated fixed film activated sludge processes, aerobic granular processes and post-anaerobic digestion. Diego has served as an Advisor to our consulting team on numerous aeration system evaluation, design and simulation/control projects.
Diego has been a Trustee of the Water Environment Federation (WEF) and serves on the American Society of Civil Engineers (ASCE) Oxygen Transfer Committee. Diego has co-authored numerous books and technical publications.
Diego is a Professor in the Department of Civil and Environmental Engineering at the University of California, Irvine (USA), where he is also Director of the Water-Energy Nexus Center.
ASSOCIATE
Juan F. Van Den Broeck
Juan is an Environmental Engineer, graduated from the Catholic University of Argentina. He is an international expert in wastewater treatment and climate change.
