Meagan Mauter, Stanford University
Host: Prof. Frank Gu
Dynamic operating schema for unit processes, treatment trains, and water systems are critical for accommodating non-steady-state system inputs and water resource demands. This applies equally to small-scale treatment units with fluctuating water production volumes and quality, large desalination plants encountering energy costs that vary as much as 10X over hourly and seasonal time scales, and entire water systems that are subject to multi-year droughts of varying intensity, persistence, and duration. This talk will discuss the paradigm shift from steady state to dynamic system operation over multiple time domains and the resulting demands this shift places on membrane-based water treatment technologies. The talk will then turn to how to leverage native flexibility in both traditional reverse osmosis (RO) technologies and emerging dynamically operated technologies (e.g., batch RO) for maximal system resiliency. Finally, this talk will address open research questions critical to characterizing the financial value of flexibility in process, treatment train and system design and motivating an expanded dynamic operational range across these systems.

Professor Meagan Mauter is an Associate Professor of Civil & Environmental Engineering and Global Environmental Policy at Stanford University and Senior Fellow in the Precourt Energy Institute and Woods Institute for the Environment. She directs the Water & Energy Efficiency for the Environment Lab (WE3Lab) with the mission of providing sustainable water supply in a carbon-constrained world. Ongoing research efforts include: 1) developing desalination technologies to support a circular water economy, 2) coordinating operation of decarbonized water and energy systems, and 3) supporting the design and enforcement of water-energy policies.
Professor Mauter also serves as the research director for the National Alliance for Water Innovation, a $110-million DOE Hub addressing U.S. water security issues. The Hub targets early-stage research and development of energy-efficient and cost-competitive technologies for distributed desalination of non-traditional source waters.
Professor Mauter holds bachelors degrees in Civil & Environmental Engineering and History from Rice University and a PhD in Chemical & Environmental Engineering from Yale University. Prior to joining the faculty at Stanford, she served as an Energy Technology Innovation Policy Fellow at the Belfer Center for Science and International Affairs, Visiting Scholar at the Mossavar Rahmani Center for Business and Government at the Harvard Kennedy School of Government, and Associate Professor at Carnegie Mellon University.
