Air Pollution Technology Fact Sheet: Paper/Nonwoven Filter- High Efficiency Particle Air (HEPA) Filter
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 ...
متن کاملNovel membrane bioreactor (MBR) coupled with a nonwoven fabric filter for household wastewater treatment.
Conventional and modified membrane bioreactors (MBRs) are increasingly used in small-scale wastewater treatment. However, their widespread applications are hindered by their relatively high cost and operational complexity. In this study, we investigate a new concept of wastewater treatment using a nonwoven fabric filter bag (NFFB) as the membrane bioreactor. Activated sludge is charged in the n...
متن کاملPhospholipid nonwoven electrospun membranes.
Nonwoven fibrous membranes were formed from electrospinning lecithin solutions in a single processing step. As the concentration of lecithin increased, the micellar morphology evolved from spherical to cylindrical, and at higher concentrations the cylindrical micelles overlapped and entangled in a fashion similar to polymers in semi-dilute or concentrated solutions. At concentrations above the ...
متن کاملAir 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...
متن کاملNonwoven Padding for Compression Management
Nonwovens play an important and crucial role in the designing of appropriate struc‐ tures for healthcare and hygiene products. One such application is the use of nonwo‐ ven padding in a multi-layer compression system recommended for the treatment of chronic venous disorders. Padding helps in ensuring uniform pressure distribution underneath the bandaging layer wrapped around the circumference o...
