The report gives results of a study of the performance of a fabric filter baghouse operated at several levels of important parameters. The primary measure of the effectiveness of control was the fiber concentration in the baghouse effluent, since overall mass efficiency is too high to detect small differences. EPA Method 5 was used to collect the samples, and the analyses were performed using an electron microscope. The tests performed showed that the optimum conditions for asbestos fiber control involve using long intervals between shakes to allow the filter matrix to build on the bag. No adverse effect on pressure drop was detected, while a 5 fold reduction in emission was demonstrated.
