Abstract/Summary

An investigation of the significance of bypass leakage in filtration systems, and in particular how this affects exposure to nanometer-scale aerosol particles when recirculation systems are used. Non-idealities of aerosol filtration represents an area with little known research. Fundamental research to investigate bypass leakage (i.e., aerosols passing around a filter without control) and recirculation (i.e., routing a filtered effluent back into a workspace) is being conducted using experimental and mathematical techniques. Research findings will not only help individuals in the workplace, but is readily applicable to chemical and biological terrorist research.
