Abstract: This tutorial will discuss engineering methods
for removing particles from gas streams. It will be taught
at an intermediate level. Factors that affect collection
efficiency and energy consumption will be discussed for
control techniques that include cyclones, scrubbers, filters,
and electrostatic precipitators. The course will begin with a
discussion of collection mechanisms and then explain how
these mechanisms can be utilized in cost-effective ways
for particle control. After taking the tutorial, students will
understand the relationships between particle properties
such as size distribution, particle collection mechanisms
such as impaction, diffusion and electrostatics, and
the performance of devices for particle control such as
respirators and large-scale industrial equipment.
David Leith is a professor in the Department of
Environmental Sciences and Engineering, Gillings
School of Global Public Health, at the University of North
Carolina at Chapel Hill. He received BS and MS degrees
in chemical engineering from the University of Cincinnati,
and the ScD in environmental health sciences from
Harvard University. He has taught graduate level courses
in aerosol technology, aerosol measurements, and air
pollution control for many years. Professor Leith has
received awards for teaching at the department, school,
and university levels.

Abstract: The average U.S. adult spends 90% of the
time indoors where personal exposure to airborne
particulate matter has been reported to be 2-10X as
high as measurements from stationary indoor monitors.
