The electrical resistivity, explosibility and collection efficienty were determined for swine dust to investigate the use of electrostatic precipitation in removing airborne dust from swine housing air. Four other organic dusts used in the resistivity and collection experiments were: flour, icing sugar, corn starch and milk powder. The electrical resistivity for each of the dusts was within the “medium” resistivity range; the range that produces the best conditions for collection by an electrostatic precipitator. An electrostatic precipitator collected the flour, icing sugar, corn starch, milk powder and swine housing dust with mass collection efficiencies of: 92.5%, 23.9%, 71.0%, 45.7% and 67.3%, respectively. For each of the five dusts the particles less than 1um, were collected with less efficiency than particles greather than 1um. An explosiveness test indicated that the swine housing dust was explosive and care should be taken when being handled.
