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, […]...

Lin Lin’s paper entitled “Investigating the void structure of the polyamide active layers of thin-film composite membranes” is published in the Journal of Membrane Science. For ~30 years, the active layer of TFC membranes has been conceptualized as a dense, nonporous film.  This study showed that ~15-40% of the active layer volume is occupied by […]...

Welcome to the Coronell Research Group

The Coronell Research Group studies water purification and energy production and storage processes, 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 group director, 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 scarcity and treatment 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.
