Our research is in the area of water quality engineering
with an emphasis on membrane separation processes and materials
science of synthetic membranes. Our current projects fall
under one of three themes:
Virus removal and concentration.
To understand how viruses can be removed from water we work
to elucidate mechanisms of virus adhesion to surfaces and
transport across porous membranes. We use this knowledge to
design membranes that can concentrate viruses with high and
reproducible recoveries. Such separations should enable accurate
quantification of viruses.
Removal of finely dispersed oil from water may be required
to meet environmental regulations. Unfortunately, the efficiency
of current separation technologies decreases dramatically
with a decrease in oil drop size. Membrane filtration can
remove smaller drops but membrane fouling by oil limits broader
acceptance of this technology. To overcome this limitation
we seek mechanistic understanding of how oil drops and films
behave at membrane surfaces. We are also developing hybrid
technologies that combine cyclonic flow and microfiltration
to remove dipersed oil.
Functional membrane materials.
Coupling membrane separation with reactions can bring about
useful synergies from lower footprint to faster reactions
to improved separation efficiency. We are exploring how nanomaterial-based
functions can be introduced into polymeric and ceramic
membranes to enhance environmentally-relevant reactions.
