ABSTRACT:
Pollutant emissions produced in the manufacture of asphaltic roofing are controlled by the use of electrified bed filters. Filter bed granules coated with pollutants are removed from the beds periodically and are used in the manufacture of the roofing. A prefilter is employed to remove varnishing pollutant components in the supermicron size range to prevent fouling of an electrical charger.
