popup.description2
The analysis of existing cavitation technologies and ultrasonic cavitation technological equipment is performed and possible ways to increase the efficiency of technological processes by creating cavitators with high intensity of ultrasonic oscillations are clarified.
The main types of microorganisms that may be present in a bacterially contaminated environment have been identified.
Preliminary microbiological studies of the effect of ultrasonic cavitation on microorganisms have been obtained to obtain the relevant acts.
The developed mathematical models made it possible to conduct numerical simulations of the operation of concentrators of acoustic oscillations in a liquid medium.
The developed hydraulic scheme made it possible to conduct appropriate research to test the effect of ultrasonic cavitation on microorganisms in the flow with the ability to control the basic parameters of this system.
Based on experimental studies to determine the optimal pressure parameters and types of materials used in the construction of cavitation equipment, recommendations are given for the creation of flow cavitation chambers, which due to the concentration of ultrasonic vibrations provides high vibration intensity and durability of radiating surfaces in cavitation medium.
The use of ultrasonic cavitators for use in the final stage of water treatment of swimming pools is proposed. On the example of a specific example, the relevant calculations are performed with the selection of the necessary equipment.
An experimental study of the processes of ultrasonic disinfection and ultrasonic filtration on the examples of practical application in specialized institutions, with the receipt of the relevant acts.
Developed and tested the design of a flowing cavitator for disinfection of small volumes of water.
