Ryan Kingsbury’s paper entitled “Osmotic ballasts enhance faradaic efficiency in closed-loop, membrane-based energy systems” is accepted for publication in Environmental Science & Technology. We tested whether the energy efficiency in a closed-loop concentration battery based on reverse electrodialysis (RED) could be increased through addition of neutral, non-permeating solutes (i.e., “osmotic ballasts”) to the dilute compa...

Alex Gorzalski’s paper entitled “Elemental composition of membrane foulant layers using EDS, XPS, and RBS” is published in the Journal of Membrane Science.  We used EDS, XPS, and RBS to characterize the foulant layers of nanofiltration membranes. We studied two different types of membranes fouled by two different water sources in two different stages of […]...

Panitan (Wan) Jutaporn’s paper entitled “Minimization of Low-Pressure Membrane Fouling Using a Magnetic Ion Exchange (MIEX®) Resin” is published in Water Research. This study showed that the efficacy of MIEX at reducing the fouling potential was inversely correlated with the content of microbial dissolved organic matter (DOM) in the source waters. Consistent with this observation, […]...

Welcome to the Coronell Research Group

The Coronell Research Group studies membrane-based processes for water purification and energy production and storage, with applications in municipal, industrial, and household systems. Research in the Coronell Lab currently focuses on: (i) membranes for water purification, (ii) salinity gradient energy, and (iii) point-of-use water treatment. A brief description of our research focus areas with specific examples of topics of interest in each area is provided in the Research section.

Our principal investigator, Dr. Orlando Coronell, teaches courses related to water treatment including Physical/Chemical Processes for Water Purification (ENVR 756), Science and Technology of Membranes for Water Purification (ENVR 890-002), and Chemical Equilibria of Natural Waters (ENVR 419, co-taught with Dr. Scott Hauswirth). A full list of the courses taught by Dr. Coronell along with their descriptions and syllabi can be found in the Teaching section.

At the Coronell Research Group, we strive to bring our research and the broader topics of water and energy to pre-college settings. We do this through educational activities at middle and high schools and through the preparation of educational materials that can be used by pre-college teachers and students. An overview of these educational activities and electronic versions of the educational materials we prepare can be found in the Outreach section. For a complete list of publications, presentations and news from our group, please visit the appropriate tab in the menu bar at the top of this page.

Fall 2016 Group: (L to R): Ryan Kingsbury, Jingbo Wang, Shan Zhu, Ariel Atkinson, Sophie Flotron, Mikayla Armstrong, Orlando Coronell.  Not pictured: Tony Perry, Kasia Grzebyk, Alex Gorzalski, Will Blanks, John Eskew.
