The presence of a surface characteristic of a liquid, when passing through which the density of a substance changes stepwise, determines a number of its properties. Liquid particles located in a layer immediately adjacent to the surface are in a state different from the state in their thickness. This difference is due to the peculiarity of molecular interaction. So, to move a molecule from the thickness of the surface to the surface, it is necessary to spend some work. This causes an increase in the power of equipment for protecting farm animals from diseases and pests, as well as an additional consumption of disinfectant liquid. In this work, material is given on the methodology and technical support of protection systems. The patterns of movement of droplets of working solutions of disinfectants in the spray torch and their effects on the treated surface are investigated. Ways to increase the effectiveness of disinfection are identified. The effectiveness of the use of disinfectants can be determined by two main criteria: physical measurements of the coating density (in the form of the number of drops per unit area, pcs. ∙ m2) and volumetric mass deposition rate (l · m2) on the treated surface of the object; biological assessment is carried out in order to determine the degree of reduction in the number of harmful objects (fungal and infectious diseases) or damage in the treated area. The relationship between physical and biological methods for assessing the effect of disinfectants on the irrigated surface is not simple, since the processing efficiency depends on many factors: droplet size; working fluid flow rates; drug concentration; retention of droplets on the target; temperature, humidity and environmental mobility, etc.
