Ultrafine particles (UFP) emitted by metal thermal spraying processes are responsible for rapid and partially irreversible clogging of filters. Granular filter beds could offer an alternative solution to media filters based on their capacity…
A process for filtering an aerosol of ultrafine metallic particles (UFP) has been designed and tested, based on the principle of a multistage granular bed. The filtration system comprised a succession of granular beds of varying thickness composed…
