Welcome to the Coronell Research Group

The Coronell Research Group studies physico-chemical processes for water purification with applications at both the treatment plant and point-of-use level.  Research in the Coronell Lab currently focuses on: (i) membrane science and technology, (ii) ion exchange, and (iii) point-of-use 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.
