The ferro-vortex apparatus relates to devices of electro-mechanical processing liquid, bulk and other blends that can be used in agriculture, medicine, chemical, oil and gas industry, communal services and other areas. The article presents the sequence conduct of analysis of the results of experimental studies to determine the effectiveness of treatment of liquid pig manure in the vortex layer of ferromagnetic particles of the ferro-vortex apparatus. During the experiment, a sample of liquid manure that was processed in a vortex layer of ferromagnetic particles was seeded on a nutrient medium and the number of colonies of microorganisms that are in the manure after treatment was calculated. Regression analysis of the results of the experiment was performed using application programs on a personal computer. A polynomial of the second degree was chosen as an approximating function. When drawing up the experiment plan, independent factors were selected, which were placed in importance (ranking). To reduce the volume of the research, insignificant factors were excluded. In the analysis, the regression equation of the results of processing liquid pig manure in the working area of the ferro-vortex apparatus and its graphical interpretation (response surface) were obtained, which allowed us to determine the optimal values of significant factors. The article shows that the quality of processing (the number of colonies of microorganisms remaining in the manure after processing in the vortex layer of ferromagnetic particles) is influenced by the mass of ferromagnetic particles in the working zone of the ferro-vortex apparatus and the ratio of the length of the ferromagnetic particle to its diameter. The size of the diameter of ferromagnetic particles affects the quality of processing slightly.
