Research evaluates electrostatic sprayers by analyzing key parameters such as flow rates, droplet size distribution, deposition efficiency, and charge levels to achieve uniform surface coverage on complex geometries. The technology enables charged droplets to wrap around surfaces, improving wetting and contact time essential for pathogen inactivation, with findings showing effective performance across materials like plastics, metals, and glass while maintaining low active-ingredient loss to air.
These advancements support more efficient disinfection in large or intricate spaces such as transit systems, schools, and workplaces, potentially reducing overall disinfectant volumes and enhancing safety in occupied environments. Validation through wetness tests and fluorescent tracing underscores the value of adjustable nozzles and power-source innovations for consistent results, contributing to refined protocols that balance efficacy with practical hygiene management.
