Abstract
The corona discharge significantly affects the cluster structure of water, leading to the formation of shock waves, cavitation oscillations, and minor ultraviolet radiation. Before initiating the water disinfection procedure with corona discharge, it is necessary to consider all factors influencing this process.. The article reviews the results of previous studies examining the dependence of the physico-chemical properties of water on its ionic composition and external thermodynamic or electromagnetic influences. The research was conducted using the ETRO-03 pilot laboratory setup with a specific frequency of 13 kHz and a voltage of 21 kV. The dependencies of physico-chemical characteristics such as dielectric and magnetic permeability, specific electrical conductivity, dielectric losses, and specific heat capacity of water were analyzed and described. The patterns of their changes due to external influences were determined based on initial parameters and variations in temperature (up to 40°C) and the frequency of the applied electromagnetic field. In alternating electric fields, an increase in frequency leads to the emergence of a relationship between the coefficient of electrical conductivity, dielectric permeability, and dielectric losses of water. The numerous parameters affected by electric influence demonstrate the complexity of the water treatment process using electric gas discharge and the various factors impacting it. The established patterns of changes in physico-chemical parameters outlined in the research can serve as a basis for planning water disinfection experiments.
