Researchers Assess Using an Electrostatic Precipitator to Improve Indoor Air Quality in Cage-Free Layer Houses
USPOULTRY and the USPOULTRY Foundation announce the completion of a funded research project by researchers at North Carolina State University that assessed using an electrostatic precipitator to improve indoor air quality in cage-free layer houses. The research was made possible in part by an endowing Foundation gift from Cal-Maine Foods. The research is part of the Association’s comprehensive research program encompassing all phases of poultry and egg production and processing. In total, more than $36,000,000 has been invested in research by the Association and Foundation. A summary of the completed project is below.
Project #F90: Using Electrostatic Precipitator to Improve Indoor Air Quality in Cage-Free Layer Houses
(Sanjay Shah, Ph.D., Biological and Agricultural Engineering Department, North Carolina State University, Raleigh, N.C.)
Dr. Sanjay Shah and colleagues with North Carolina State University recently completed a research project with the overall objective of developing and evaluating a recirculating electrostatic precipitator (ESP) for its ability to improve indoor air quality in cage-free layer houses with litter floors. Specific objectives were to design and fabricate a full-scale recirculating ESP unit; evaluate the removal efficiency of the ESP in the cage-free layer house for particulate matter, ammonia, and airborne bacteria and fungi; and evaluate the impact of the ESP on barn indoor air quality for particulate matter. The central hypothesis of this research was that a recirculating ESP could reduce dust concentrations and thermal stratification in winter when ventilation rates are low and dust concentrations are higher.
