Filtration of Solid Aerosols
Résumé
During filtration, the collection of particles by the filter results in an increase in the pressure drop across the filter. For solid aerosols, this evolution, based on filtration time or the mass of the collected particles, can typically be divided into three phases. The duration of each phase is based on the filter media, the aerosol and operating conditions. Each phase is separated by more or less clearly marked transition zones
