The electric discharge in special cavitation mode is an effective instrument for water disinfection, intensification of extraction, and material dispersion. The object of this work is to study the influence of individual elements and characteristics of electric discharge installations on the intensity of electric discharge cavitation. The influence of electric discharge installations’ parameters and the constructive features of the working chamber on the intensity of electric discharge cavitation is considered. Simple ways to increase cavitation intensity during special modes of electric discharge are shown. The dependence of the intensity of electric discharge cavitation on design features of the technological part of the installation: working chamber and electrode system is shown. The use of an electrode system with a movable plain electrode-cathode allows to increase intensity of cavitation. Increasing the level of liquid above the electrode system leads to a decrease in the intensity of cavitation, and increasing of surface area of liquid in the working chamber allows to increase intensity of cavitation significantly. The obtained results open up practical prospects for the use of electric discharge cavitation in the conditions of industrial chemical-technological processes. The research demonstrates that optimizing electric discharge cavitation processes aligns with the principles of green solutions for environmental safety, providing effective and sustainable approaches for industrial applications such as water treatment, material processing, and chemical-technological processes.
