“…Numerous studies have demonstrated the virucidal activity of ECAS a against a broad range of targets [48, 51, 61, [92][93][94][95][96][97], comparable to that of other biocidal agents [92]. Most methodologies expose virus particles in suspension to ECAS a in the presence/absence of organic loading, whereby ECAS a reduces the number of viable virus particles as measured by cytopathic effects of the target virions in subsequently infected cell lines [48,51].…”

Due to the limitations associated with the use of existing biocidal agents, there is a need to explore new methods of disinfection to help maintain effective bioburden control, especially within the healthcare environment. The transformation of low mineral salt solutions into an activated metastable state, by electrochemical unipolar action, produces a solution containing a variety of oxidants, including hypochlorous acid, free chlorine and free radicals, known to possess antimicrobial properties. Electrochemically activated solutions (ECAS) have been shown to have broad-spectrum antimicrobial activity, and have the potential to be widely adopted within the healthcare environment due to low-cost raw material requirements and ease of production (either remotely or in situ). Numerous studies have found ECAS to be highly efficacious, as both a novel environmental decontaminant and a topical treatment agent (with low accompanying toxicity), but they are still not in widespread use, particularly within the healthcare environment. This review provides an overview of the scientific evidence for the mode of action, antimicrobial spectrum and potential healthcare-related applications of ECAS, providing an insight into these novel yet seldom utilised biocides.

“…[11]. In addition, it could disinfect hepatitis B virus and human immunodeficiency virus [12] and reduce germinations of many fungal species [10]. EOW can also be used in agriculture for sterilization of fruits and vegetables [13], food materials and food processing materials [14,15] studied using acidic EO water to treat fresh-cut vegetables, and achieved up to a 2.6 log10 CFU/g reduction in bacterial population.…”

Electrolyzed Oxidized Water (EOW) is produced by passing a diluted salt solution through an electrolytic cell, having anode and cathode electrodes. The anode and cathode are separated by a bipolar membrane. Negatively charged ionschloride and hydroxide in the diluted salt solution move to anode to give up electrons and become gas (O 2 , Cl 2 ) and hypochlorous acid and having redox potential of +700 to +800 mV with pH 4.0. It has a strong oxidation potential and a shortage of electrons giving it the ability to oxidize and sterilize. In microbial inactivation process, oxidized water damage cell membranes, create disruption in cell metabolic processes and essentially kill the cell. EOW, also a strong acid, is different to hydrochloric acid or sulfuric acid in that it is not corrosive to skin, mucous membrane, or organic material. It is easy to handle and suitable for the sanitation of the plant and decontamination of foods. Electrolyzed water has been tested and used as a disinfectant in the food industry and other applications.

“…The main stage of electrochemical treatment of water is the electrolysis of water or aqueous solutions with low mineralization as aqueous solutions of 0,5-1,0% NaCl [3], which occurs in the electrolysis cell, consisting of the cathode and the anode separated by a special semipermeable membrane (diaphragm) which separates water to alkaline fraction -the catholyte and acidic fraction -the anolyte (Figure 1). When the passing over the electric current through water, the flow of electrons from cathode as well as the removal of electrons from water at the anode, is accompanied by series of redox reactions on the surface of the cathode and anode [4].…”

This paper deals with the evaluation of the basis of the mathematical model of interaction of electrochemically activated water solutions (catholyte/anolyte), obtained in the diaphragm electrolysis cell, with water and sodium chloride and the basic physical-chemical processes underlying the electrolysis of water as well. In order to provide additional data about the distribution of H 2 O molecules according to the energies of hydrogen bonds in the electrochemically activated water solutions of the catholyte and the anolyte, the non-equilibrium energy spectrum 72 European Reviews of Chemical Research, 2015, Vol.(4), Is. 2 (NES) and differential non-equilibrium energy spectrum (DNES) of the anolyte and the catholyte were measured as a result of which were established the basis for evaluation of the mathematical model explaining the behavior of the anolyte and the catholyte regarding the distribution of H 2 O molecules to the energies of hydrogen bonds. The local maximum for catholyte in the NESspectrum was at -0,1285 eV, for anolyte -at -0,1227 eV and for the control sample of deionized water -at -0,1245 eV. The calculations of ∆E H...O for catholyte with using the DNES method compiles (-0,004±0,0011 eV) and for anolyte (+1,8±0,0011 eV). The average energy of hydrogen bonds between Н 2 О molecules was measured by the DNES method to be compiled at -0,1067±0,0011 eV.Keywords: electrochemical treatment of water, electrolysis, anolyte, catholyte, NES, DNES. IntroductionThe phenomenon of electrochemical activation of water (EAW) is a set of electrochemical and electrical processes occur in water in the electric double layer (EDL) type of electrodes (anode and cathode) with non-equilibrium electric charge transfer through EDL by electrons under the intensive dispersion in water the gaseous products of electrochemical reactions [1]. In 1985 EAW was officially recognized as a new class of physical and chemical phenomena.As a result of the treatment of water by a constant electric current at electric potentials equal to or greater than the decomposition potential of water (1,25 V), water goes into a metastable state, accompanied by electrochemical processes and characterized by the abnormal activity levels of electrons, the redox potential, and other physical-chemical parameters (pH, Eh, ORP) [2].During the EAW occur four main processes: 1) Electrolytical decomposition of water by electrolysis on account of redox reactions on the electrodes due to the external electric field;2) Electrophoresis -the movement in the electric field of a positively charged particles and ions toward the cathode and negatively charged particles and ions toward the anode;3) Electroflotation -the gas formation and flocculation of aggregates consisting of finedispersed gas bubbles (H 2 at the cathode and O 2 at the anode) and suspended solids in water; 4) Electrocoagulation -the formation of colloidal aggregates of particles of deposited disperse phase through a process of anode dissolution of the metal and the formation of metal cations Al...
