摘要：

Physical processes occurring after placing the filter diaphragm in cavitation medium created by ultrasonic wave, the intensity of which exceeds the threshold of cavitation conditions have been studied. The behavior of cavitation bubble and pollutant particle in ultrasonic field are analyzed making it possible to build a mathematical model of the water filtration process in ultrasonic medium. The impact of different factors on the cavitation intensity was also studied. Experiments were conducted to investigate the impact of static pressure on the intensity of cavitation erosion by using the erosion test method. Aluminum foil was used as a test material. Experiments were conducted in the cavitation chamber at the low and increased values of static pressure with respect to its atmospheric value.
