“…1, 2a, and 2b). The choice of microbial culture is related to the dominance of these bacteria types among prokaryotes found by us in natural waters [4]. Therefore, in the processes of cavitation water disinfection studies of the influence of bubbled gas on the viability of these microorganisms are presented.…”

Features of growth of microorganisms on a nutrient medium and their microscopic researches were studied. Cavitation treatment (22 kHz, 91 W, 1.65 W/сm3) of water with the simultaneous action of bubbled inert gases (argon and helium) on the viability of microbial cells (Diplococcus and Sarcina) are presented. The highest water disinfection was obtained for water samples with Sarcina lutea cells for both used gases under cavitation conditions. Both investigated types of cocci bacteria were destroyed faster under Ar/US-action after comparison of the effectiveness of the gas nature action on the water disinfection.

“…Therefore, the determination of the parameters of acoustic treatment of technological media and energy requires the use of a computational model [10], which takes into account these changes. The key parameter of the evolution of gas and air bubbles in the acoustic field is the pressure that is formed in the contact zone of the «cavitator -medium» system [11][12][13][14]. The specified parameters and characteristics (Fig.…”

The operation process of acoustic treatment of technological media is investigated. The assessment and substantiation of methods for studying the parameters of acoustic treatment of technological media is done. The functional relationships between the acoustic parameters of the cavitation apparatus and the rheological properties of the processing technological media have been revealed. The process of staged acoustic treatment of technological media is described. A number of criteria and key parameters were determined, the use of which was carried out as an assessment in the calculation algorithm, depending on certain known initial data of the cavitator and the medium. The values of the input resistance of the compensator are determined and the condition for the maximum transfer of energy from the acoustic apparatus to the technological medium is obtained. To calculate the parameters of the «cavitator -technological medium» ultrasonic cavitation system, an algorithm and method for creating a synergistic system were developed.
