| Abstract |
This article presents a new method for testing filter media used in industrial dust control. It enables the monitoring changes in the characteristics of the media, such as the pressure drop and fractional filtration efficiency during use characterized by a succession of clogging and unclogging cycles. The test aerosol is composed of alumina particles with a volume median diameter of 3.2µm. Unclogging is ensured by injecting a back flow of compressed air. Results of tests carried out on three types of media used in industrial dust control are presented. Their performance was determined at the initial state (new filter) and after 40 clogging-unclogging cycles. The selected performance criteria enable comparisons to be made among the various media and provide guidelines for selecting a medium as a function of the industrial application. |
