Air Pollution Technology Fact Sheet: Paper/Nonwoven Filter- High Efficiency Particle Air (HEPA) Filter

ثبت نشده
چکیده

3. Applicable Pollutants: Submicron Particulate Matter (PM) greater than or equal to 0.3 micrometer (μm) in aerodynamic diameter, and PM greater than or equal to 0.12 μm in aerodynamic diameter that is chemically, biologically, or radioactively toxic; hazardous air pollutants (HAPs) that are in particulate form, such as most metals (mercury is the notable exception, as a significant portion of emissions are in the form of elemental vapor).

Air Filter Devices Including Nonwoven Meshes of Electrospun Recombinant Spider Silk Proteins

Based on the natural sequence of Araneus diadematus Fibroin 4 (ADF4), the recombinant spider silk protein eADF4(C16) has been engineered. This highly repetitive protein has a molecular weight of 48kDa and is soluble in different solvents (hexafluoroisopropanol (HFIP), formic acid and aqueous buffers). eADF4(C16) provides a high potential for various technical applications when processed into mo...

Use of a Portable Hepa Air Cleaner in a Hospital Ward for Reducing Disease Infection

Use of a portable HEPA filter cleaner in a room is believed to be capable of reducing the risk of transmission of infectious diseases through removing the particles or large droplets to which pathogens are attached. It is hoped that the portable HEPA filter(s) can increase the effective air change rate (for particle removal only) in a general ward to the ventilation standard of an isolation war...

Filtration behaviour of woven and nonwoven fabrics

The filtration behaviour of woven and nonwoven fabrics at different air flow rate, dust feed rate, dust loading, time intervals and dust particles has been studied. It is observed that the pressure drop increases with the increase in airflow rate for both the woven and nonwoven filters. In general, the pressure drop in case of woven filter is found to be higher than that in case of nonwoven fil...

Performance of Multiple HEPA Filters Against Plutonium Aerosols

Field sampling has provided C. Elder, and Manuel Gonzales general criteria defining plutonium aerosol size characteristics and activity concentrations from typical plutonium operations. Two fabrication facilities have aerosols with activity median aerodynamic diameter’s (amad) ranging from 2 to 5 pm; the two research and development facilities indicate amad’s ranging from 1 to 4 ~; and a recove...
