On Cleaning Membranes

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.

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.
