Jan. 17 - "On Cleaning Membranes" by Dr. Michael J. Semmens


University of South Florida – Civil & Environmental Engineering
Environmental and Water Resources Engineering Graduate Seminar – Spring 2014


On Cleaning Membranes
Michael J. Semmens PhD, PE.
Civil Engineering, University of Minnesota
Friday, January 17, 12:20-1:10
Room 4 ENG Building


Abstract. There have been many studies conducted on membrane fouling and membrane cleaning.  Model studies, batch studies, continuous flow studies with different membranes, different model compounds and different operating conditions etc.  The results are, not surprisingly, difficult to compare. As such, cleaning remains more art than science and many operators use a trial and error approach to determine what works best for their specific application.  This talk will review the field of membrane cleaning with an emphasis on the chemical approaches for removing organic foulants and biofilms.  The talk will also highlight the impact of the chemicals on membrane integrity and performance.

Biosketch. Dr. Michael J. Semmens is a Professor Emeritus in the Department of Civil Engineering at the University of Minnesota.  His research interests are in chemical and physical processes for water, wastewater, and hazardous waste treatment, with expertise in membrane applications in water and waste water treatment, membrane bioreactor design, the design of composite membranes and membrane modules for environmental applications, passive barrier membranes for in-situ bioremediation of chlorinated organic compounds, and biofilms grown on gas-permeable membranes.
