  • Reducing the risk of dust explosion hazards

    In the wake of recent tragic and highly publicized dust explosions, companies are asking, 'Could that happen here?' and 'What can I do to prevent such an incident at my facility?' One approach is to manage dust explosion hazards as though they were subject to OSHA’s Process Safety Management (PSM) requirements (29 CFR 1910.119), even though dust hazards often are not covered under this ...

  • White Paper - Forward Scatter Visibility Meters (FSM)

    The use of Biral Forward Scatter Visibility Meters in the presence of haze, smoke and sandstorms The performance of forward scatter meters (FSM) in the presence of haze, smoke and dust is sometimes questioned as the fundamental operation of such devices is defined for hydrometeors (mist and fog) rather than for lithometeors (haze, sand, dust and smoke). This note explains why forward ...

  • Aerosol filtration in nanofiber filter media

    Nanofiber filter media are used in air filter applications where a compact filtration system with very high overall and fractional efficiency and low initial pressure drop  is required.  Moreover, because the aerodynamic drag force on nanofibers is very low compared to the drag on the large dust particles collected on the nanofiber media, this media is ideal for application to ...
