Evaluation of a Pilot-Scale Electro-nanospray System for Decontaminating Pig Barns
In this study, an electro-nanospray system was developed for pig barn decontamination. This technology generates engineered water nanostructures (EWNS) through electrospraying and ionization of reverse osmosis (RO) Water. The highly charged nano-scale water droplets encapsulate reactive oxygen species (ROS), which are responsible for bacterial inactivation and for capturing particulate matter through electrostatic forces. Specifically, this study aimed to 1) Determine the decontamination performance under a broad range of operating parameters such as airflow rate and number spray injectors in laboratory-scale chambers; 2) Evaluate the performance of the electro-nanospray system in inactivating airborne bacteria, reducing gases and dust levels in small-scale pig rooms; and 3) Evaluate the performance of an electro-nanospray system in decontaminating barn surfaces.
Results suggest that the electro-nanospray system can provide an innovative approach to mitigating air quality as it can reduce levels of bacteria, dust, and gases. In addition, no chemical residues remain; thus, it can be a sustainable and environment-friendly treatment technology for barn air and surface decontamination.
