Abstract |
Four different types of electrostatic filter material were exposed to a range of aerosols. Different aerosols varied considerably in the extent to which they caused loss of efficiency of the filters. Simple dry dusts and asbestos caused little effect, but foundry aerosols were more damaging to all filters, and coke-oven fume to filters made of soluble polymers. It is concluded that although degradation of electrically charged materials occurs when they are exposed to aerosols, significant electrical activity remains; and even if all the effects of the carge were removed, they would be no worse than mechanical filters of the same structure. A simple theory of degradation is outlined. |
