The electrical resistivity and collection efficiency of pig dust were determined to investigate the use of electrostatic precipitation in removing airborne dust from pig housing. Pig dust was compared with 4 other organic dusts in resistivity and collection experiments: flour, icing sugar, maize starch and milk powder. The electrical resistivity for each of the dusts was within the “medium” resistivity range. An electrostatic precipitator collected the flour, icing sugar, maize starch, milk powder and pig dust with mass collection efficiencies of 92.5, 23.9, 71.0, 45.7 and 67.3%, respectively. For each of the 5 dusts, particles <1 um were collected less efficiently than particles >1 um.
