Research activities

The Coronell Research Group studies physico-chemical processes for water purification with applications at both the treatment plant and point-of-use level. Currently, research in the Coronell Lab focuses on two main areas: (i) membrane technology, and (ii) redox processes. Our work on membrane technology aims to advance the understanding of the mechanisms of transport of water and contaminants through reverse osmosis and nanofiltration membranes, and fouling in low-pressure and high-pressure membrane processes. We are also interested in developing new improved membranes. Our work on redox processes currently focuses on the development of point-of-use systems for the removal of heavy metals. Applied projects addressing specific needs of plants or municipalities are also in progress.
