Description: Particulate matter (PM) emission is one of the health and environmental issues associated with animal production, particularly for poultry. The fine fraction of airborne PM (with aerodynamic diameter ? 2.5 ?m) is of greater concern because it can penetrate deeper into the lung?s gas-exchange region. One of the techniques employed for PM control is electrostatic precipitation (ESP), which removes airborne PM through electrostatic forces. Although ESP has been effectively implemented in industrial plants for PM removal from flue gases for many decades, its application in livestock facilities has just been recently tested; hence, more studies are needed to evaluate and improve its potential. In this study, dust and bacterial removal efficiencies of a commercially available ESP was assessed in two identical pullet rooms at the Poultry Research and Teaching Unit at the University of Saskatchewan. Reductions of up to 70% of total dust and 45% of PM10 and PM2.5, monitored through gravimetric methods, were observed over a 43-day trial period. Bacterial reductions evaluated through plate count method were up to 33%. These findings suggest that ESP is an effective technology for PM removal in poultry houses. The technique will be further assessed in larger scale studies to better understand its effectiveness in commercial poultry operations.
