“…Tap water used for the preparation of the suspension had the following characteristics: hydrogen index -6.7, the total number of insoluble particles -320 ppm, specific conductivity -0.45 μSm/cm, redox potential -268 mV. In the course of the experiment, the changes of these parameters for the obtained extracts were investigated (Malyushevskaya et al, 2021). Control samples of polysaccharides aqueous extract from hyssop («Control») were prepared according to (State Pharmacopoeia of Ukraine, 2007).…”

The principles of sustainable development and green chemistry are priorities in the development of new technologies for the extraction of useful biologically active substances, for example, in the manufacture of medicines. The processes of extracting substances from plant raw materials have many applications. Intensification of such processes, reducing their duration, energy consumption and consumption of the extractant is urgent. The object of the reseach is the green approach to intensify the extraction processes of polysaccharide substances from plant materials. The research methodology was experimental with statistical data processing. In the field of experimental research was the process of the influence of pulsed, alternating and direct current on the intensity of aqueous extraction of polysaccharides from plant materials. The high efficiency of intensification of extraction by a pulsed electric field was studied. The process can reduce the time for obtaining water-soluble polysaccharides by 3 times in comparison with traditional pharmacopoeial convection methods and reduce energy consumption by 20 times. The significance of the pulse current parameters for effective extraction was determined: the referred pulse shape, the frequency of the pulse current for extracting the maximum amount of water-soluble polysaccharides, the pulse duration, and the optimal processing time. The green approach to the use of a moderate electric field of pulsed current to accelerate the extraction of biologically active substances is the basis of the method of intensification of other traditional mass transfer processes for the sustainable development of technology.

“…Much attention is paid to both traditional methods of removing heterogeneous impurities of biological origin (chlorination, ozonation, ultraviolet radiation treatment), and non-traditional ones (e.g., plasma and membrane technologies). Attention should be paid to electrical methods that have demonstrated their effectiveness for the intensification of various processes [14][15][16].…”

Water treatment, such as disinfection, is an integral stage of its use for human life. The use of plasma technology with high-voltage electric discharge in a liquid for obtaining a bactericidal effect is discussed. It has been experimentally shown that among the factors accompanying a high-voltage electric discharge in a liquid and affecting the viability of bacteria, cavitation is the main one. Simultaneous use of electric discharge in the special cavitation mode and oxidizing agents makes it possible to achieve stable disinfection of water. At the same time, bactericidal doses of the oxidizing agent are reduced by a factor of 10 relative to existing standards, and the energy costs for electric discharge exposure, enhanced by small doses of an oxidizing agent, are reduced by 6 times compared to the costs of disinfection by only an electric discharge.
