Description:
This paper reviews the results of fine particulate control technology tests by the Particulate Technology Branch (PATB) of EPA's IERL-RTP over the last 3 years. The review covers characterization of conventional control equipment, assessment of the collectability of dusts, and new idea evaluation and identification. Results from electrostatic precipitator (ESP) tests show that they can control the removal of particles smaller than 2 micrometers better than was previously thought. ESP field charging does not reach its minimum until well below the 1.0 micrometer size. Scrubbers show a dramatic decrease in efficiency as the particle size drops. The most efficient scrubbers also require the most energy. Fabric filters, although limited in control abilities by the filter media, show satisfactory effectiveness in the control of fine particles. Even though only four novel devices are now under consideration by IERL-RTP, testing on them proved successful, and the future appears promising for their control of all emitted particulate matter.
