“…The atomized droplets play the role of “seed particles” and form an aggregation nucleus in the aerosol that can effectively collide with the surrounding fine particles to improve the aggregation efficiency. After the disinfectant is atomized, a large amount of water vapor is emitted in the air to increase the indoor relative humidity, improve the penetrating ability of the disinfectant on the bacterial wall, enhance the disinfection effect, and reduce the disinfection time ( Muñoz et al, 2017 ).…”

To better understand the effect of different disinfectants on the types and quantities of microorganisms in a broiler chicken house, five different types of disinfectants, including ozone, available chlorine, quaternary ammonium salt, glutaraldehyde, and mixed disinfectant, were used. The broiler house microbial communities were analyzed by high-throughput sequencing combined with air sampling. The results showed that the concentrations of airborne aerobic bacteria in the empty broiler houses after application of different disinfectants were significantly reduced compared to a house untreated with disinfectant (P < 0.05 or P < 0.01), and the number of inhalable particles of airborne aerobic bacteria sharply decreased after disinfection. Of the five disinfectants, the mixed disinfectant had the best disinfection efficacy on the total microbial communities (P < 0.05). A total of 508,143 high-quality sequences were obtained by high-throughput sequencing, which identified 1995 operational taxonomic units. In total, 42 phyla and 312 genera were identified. The structures of airborne microbial communities in the broiler houses after the different disinfectants were applied differed. In the house treated with the mixed disinfectant, the microbial communities containing opportunistic pathogens, such as Escherichia-Shigella, Bacillus, and Pseudomonas, had the lowest abundance, with a significant decrease compared to the house untreated with disinfectant. The alpha diversity index showed low diversity of the microbial communities in the house treated with mixed disinfectant. In contrast to the other four disinfectants, only a small amount of bacteria was detected in the air sample in the house treated with the mixed disinfectant; specifically, only four phyla were found (Proteobacteria, Bacteroidetes, Actinobacteria, and Firmicutes). The mixed disinfectant produced a positive effect on disinfection for four phyla; however, it didn’t thoroughly eliminate them. At genus level, Bacillus, Arenimonas, and Shinella could not be detected in the house treated with the mixed disinfectant, but were detected in houses treated with other disinfectants. The high-throughput sequencing results revealed that the combination of multiple disinfectants exhibited a good disinfection efficacy and that this technique could disinfect the air of broiler houses. These results will help guide the development of a reasonable program for broiler house disinfection.

“…Particle size is extremely important for the nebulization of liquid drugs. In comparison, the water particles atomized by the five types of LN devices were smaller than those generated by typical PZT devices, which produced water particles with a diameter of around 7 µm [31] , [32] . Furthermore, to compare studies with the PZT and LN, the materials of the atomization device, the driving frequency, the particle peak size, solutions and the vibration mode are summarized ( Table 1 ) [33] , [34] , [35] , [36] .…”

“…Ramisetty et al (2013) proposed a correlation for the Sauter mean diameter using experimental data from aqueous glycerine and aqueous methanol solutions [8]. Muñoz et al (2018) modified Rajan and Pandit's dimensionless numbers and fitted a correlation for the number mean diameter of an aqueous methanol solution [9]. In this paper, correlations to estimate the number, surface, volume, and Sauter mean diameter are fitted.…”

The calculation of the spray characteristics from the physical parameters that model the atomization process is required to develop atomizers for practical applications. In this paper, a model for the thin-film ultrasonic atomization and its dimensionless numbers are presented, the model is based on the capillary wave theory enhanced by cavitation. Experimental distributions of high-frequency atomized sprays are sampled for aqueous ethanol and aqueous glycerine mixtures using the immersion method. Correlations for the number, surface, volume, and Sauter mean diameters based on the dimensionless numbers are fitted and validated from the experimental data.
