A study of the dose reduction benefits of electrostatic precipitation in the capture of radionuclide aerosols produced during decommissioning processes
… This work proposes the employment of electrostatic precipitators (ESPs) as area filters that capture radionuclide aerosols produced during nuclear dismantlement. These filtration systems demonstrate advantages in a nuclear dismantlement context over other filtration systems: they …

Experimental and analytical investigation for diesel smoke elimination
… EPA in the 1990's. Diesel smoke elimination via electrostatic precipitation was studied. A diesel smoke eliminator with corona charging and particle collection sections was developed, built, and tested. This device, with its high efficiency and a minimal increase in back pressure of the engine, …

A reduced-turbulence, reduced-entrainment electrostatic precipitator
This thesis describes testing of an electrostatic precipitator that has a portion of the main precipitator flow drawn through a porous (fabric) collecting surface. Tests investigated effects of flow through the collecting surface (side flow) on precipitator turbulence and particulate removal …

Low-cost air particulate monitor based on particle capture and imaging
… developed and validated. Two capture techniques, electrostatic precipitation (ESP) and fiber-filtration, are demonstrated and verified with corresponding imaging results. Particulates captured either on flat substrate or aligned fibers are illuminated by LED light source with a glancing angle, or …

A Study of the Bulk Electrical Resistivity Characteristics of Fly Ash from Lignite and Other Western Coals
… Fly ash can be removed from gases using electrostatic precipitation. Efficiency of precipitation depends to a large extent on the bulk electrical resistivity of the fly ash which in turn depends on conditions such as ash temperature, moisture content of the gas, and ash composition. Bulk …

The use of fly ash to make a building material
… one of several ways, the most important being by electrostatic precipitation, wet scrubbing, and with cyclone separators. It must then either be used or disposed of. Several attempts have been made to use fly ash for some useful purpose, but it is not adaptable for filling in, for road …

Current distribution and particle motion in a barbed plate electrostatic precipitator
… more favorable electrical and flow conditions in electrostatic precipitators. A novel barbed plate precipitator is designed to provide a more uniform current density distribution and electric field in the inter-electrode gap. Ground plate current densities of both a conventional wire-plate …

Compact, Self-Cleaning Wet Electrostatic Precipitators
Clean air is essential for public health, but current air filters often come with trade-offs— they remove harmful particles effectively but cause high pressure drops and need frequent replacements. In this project, we developed a new kind of air-cleaning system. Our design allows air to flow freely …

Experimental study of electrostatic aerosol filtration at moderate filter face velocity
Electrostatic filtration media (electret) has been used in many applications due to its ability to efficiently collect submicron particles while maintaining a low pressure drop. Filter face velocities have ranged from 0.01-0.5 m/s in previous studies. However, in this study, measurements were …
