Aerosol Nanoparticle Control by Electrostatic Precipitation and Filtration Processes—A Review

Electrostatic Precipitation

Electrostatic precipitators have been used widely in industry, and play an important role in environmental protection. Electrostatic precipitator (ESP) can be operated with a high collection efficiency and a low pressure drop. Recently, ESP also has been used for cleaning indoor air. In this review, principles of electrostatic precipitation, such as particle charging, migration velocity of char...

The WMO/IUGG INTERNATIONAL AEROSOL PRECIPITATION SCIENCE ASSESSMENT GROUP (IAPSAG) Aerosol Pollution Impact on Precipitation: A Scientific Review

Substantial convection and precipitation enhancements by ultrafine aerosol particles.

Aerosol-cloud interactions remain the largest uncertainty in climate projections. Ultrafine aerosol particles smaller than 50 nanometers (UAP<50) can be abundant in the troposphere but are conventionally considered too small to affect cloud formation. Observational evidence and numerical simulations of deep convective clouds (DCCs) over the Amazon show that DCCs forming in a low-aerosol environ...

Improvement of Air Quality in Vehicle Cabins by Nanoparticle Filtration

A filter system is presented which allows the reduction of the concentration of ultrafine particles in vehicle cabins to very low levels. The original ventilation system is switched to the recirculation mode and all cabin intake air is supplied via a retrofitted filter system. Tests with a variety of different vehicles (from passenger cars to coaches) show the efficiency of the system. Filters ...
