The research objectives were to develop and evaluate a practical dust removal method for livestock housing using ionization and electrostatic precipitation. Prototype testing was conducted in an animal production unit to obtain a quantitative estimate of dust removal under typical operating conditions. Two animal chambers with similar ventilation, temperature control, and management were used. Each chamber housed 48 nursery pigs. Particle count and mass samples were collected. Particle counts were measured with a Royco Model 225 Aerosol Particle counter. Particle count data was recorded as particle numbers between thresholds. The recorded ranges were 0.5 up to 1.0 micron, 1.0 up to 2.0 micron, 2.0 up to 5.0 micron, 5.0 up to 10.0 micron and greater than 10.0 micron. Mass samples were taken with a 0.8 micron filter and vacuum pump. All systems studied resulted in a significant reduction in airborne dust concentration. Without ionization, typical particle counts were between 76-169 million particles per cubic meter (mppcm). With ionization dust control, typical particle counts were between 38-86 mppcm. A percent reduction of 57% to 66% of all dust particles was achieved with ionization. Comparing particle count data with mass sample data indicates that larger size particles are removed more effectively than smaller particles.
