Abstract
The paper presents a flow plasma reactor permitting modification of the properties of water/aqueous solutions by stochastic resonance amplification of vibrations of selected chemical species in water with electromagnetic noise generated during a plasma discharge. The main parameters characterizing the quality for super-pure water, tap water and water from the intake in Besko (Poland) before and after the process in the plasma reactor were presented for comparison. In addition, the 17O NMR (the full width at half maximum) and electrospray ionization mass spectrometry (ESI MS) methods were used to determine differences in physicochemical parameters between the untreated and plasma-treated water. It has been established that the water subjected to plasma treatment shows much different gas absorption properties than the untreated water samples, as a function of temperature and pressure, in this paper we report exemplary data for CO2, oxygen and acetylene. The improved gas absorption properties of the plasma-treated water make it attractive for the use in industrial processes. It is worth pointing to a great capacity of the new reactor (4000 l/h), and low energy consumption (20 MJ/h) for the treatment of the above mentioned volume flow rate of water.

It has been established that the water subjected to plasma treatment shows much different gas absorption properties than the untreated water samples, as a function of temperature and pressure, in this paper we report exemplary data for CO2, oxygen and acetylene
The energies corresponding to the frequencies of the generated noise are in resonance with those of vibrations of different water structures, different chemical species and molecules contained in water
In the previous paper [26], on the basis of electrospray ionization mass spectrometry (ESI MS) study of water samples before and after plasma treatment, we showed that this process significantly affects the solvation of ions in a solution
Summary
Water is known to be the most abundant chemical compound in the Universe. Due to its properties, water, at least on the Earth surface, does not exist as a pure hydrogen-oxygen (H2O) compound. Knowledge of the properties of water (water solution) at the molecular level controlled and forced by external factors allows better understanding of the impact of water on living organisms at the cellular level, and permits deeper insight into the processes in living organisms. These two factors: the cluster structure of water forced by the formation of hydrogen bonds between H2O molecules and the solubility of chemical compounds and gases in water, modify the water properties in response to physical and chemical external factors [6] [7] [8]. Implementation of a similar approach by Acoustic Wave Separation, led to industrial water cleaning process using a pattern of ultrasonic waves to exert acoustic forces on hydrocarbons and other water contaminants [24]
