Electrostatic Fibrous Filter

Electrostatic forces in fibrous filters—a review

Among various devices for removing submicrometer particles from a gas stream, fibrous filters have the advantages of providing high collection efficiencies at low-pressure drop. Even in the absence of electrostatic forces, a fibrous filter captures particles efficiently by inertial impaction, interception, and convective Brownian diffusion. Application of electrostatic forces can significantly ...

Simulation of cake formation for nano-fibrous filter media using image processing

Craniofacial Fibrous Dysplasia

Fibrous dysplasia (FD) is an osseous growth dis-order, producing immature bone and characte-rized by the replacement of normal bone with fibro-osseous connective tissue. It is a bone dys-plasia that has the potential to cause significant cosmetic and functional disturbances, particularly in the craniofacial skeleton. Cra-niofacial fibrous dysplasia is one of the three types of polyostotic fibro...

Design of fibrous filter media based on the simulation of pore size measures

Filtration media including woven cloths, nonwoven, membranes and particulate beds are used in a wide variety of applications such as biotech, health care, pharmaceutical, food and beverages, power sources and chemical industries. One way to characterise the performance of all these filtration media is by the pore structure characteristics of the media. Several experimental techniques are availa...

Filter Performance Degradation of Electrostatic N95 and P100 Filtering Facepiece Respirators by Dioctyl Phthalate Aerosol Loading

Polydisperse dioctyl phthalate (DOP) aerosols are employed for testing filter penetration with loading of Rand P-series particulate filters for National Institute for Occupational Safety and Health (NIOSH) certification. Penetration for filters must not exceed NIOSH allowed maximum levels during the entire loading of 200 mg DOP indicating no filter degradation. Degradation of respirators loaded...
