Introduction
Electro-Chemical Activation (ECA) is the generation of safe, effective, environmentally friendly disinfectants and cleaners by passing ordinary water containing dissolved sodium chloride through an electrolytic cell. Technology_1Traditional electrolysis cells are only capable of generating small volumes of unstable, low pH oxidized water and the formation of hypochlorite (bleach).
The generator utilizes electrolytic cells where the anode chamber is separated by a unidirectional permeable membrane from the cathode chamber. This allows migration and separation of the ions to prevent the production of gaseous chlorine (CL2) while generating large volumes of neutral pH HOCL that is highly biocidal, but has a very low chemical load as compared to Sodium hypochlorite.
How It Works
Technology_2Ordinary tap water containing a low concentration of sodium chloride (NaCl) is passed through an electrolysis chamber containing an anode (positive electrode) and cathode (negative electrode) that is separated by a unidirectional, permeable diaphragm.
Positive ions (cations) are drawn towards the cathode where they receive electrons from the electron-rich cathode to form sodium hydroxide (NaOH), a cleaning fluid with the ability to reduce bacteria and pathogens.
At the anode, negative ions (anions) are attracted and surrender their additional electrons to the electron-depleted anode to produce hypochlorous acid (HOCL), a powerful disinfecting fluid which has superior germicidal, biocidal and sporicidal properties that can eliminate pathogens such as Methicillin-resistant Staphylococcus aureaus (MRSA), Vancomycin-resistant Enterococci (VRE), Human Immunodeficiency Virus Type 1 (HIV-1), and more.
There are very many reactions that occur when water (H2O) is electrolyzed, for example (E0 is the standard redox potential):
O2 + H + e- HO2 E0 = – 0.13 V [1]
2H+ + 2e- H2 E0 = 0.00 V [2]
HO2 + H+ + e- H2O2 E0 = +1.50 V [3]
O3 + 2H+ + 2e- O2 + H2O E0 = +2.07 V [4]
OH- + H+ + e- H2O E0 = +2.85 V [5]
H2O + e- H+ OH- E0 = – 2.93 V [6]
OH+ e- OH- E0 = +2.02 V [7]
The above equations are not a complete list, but give examples of some of the reactions that take place. Notably, they show that electrolysis of water produces H+ and OH ions, H and OH radicals, H2, O2, HO2, O3 and the like due to redox reactions. As a direct result of electrolysis, hydrogen and ozone gas are released and a percentage of hydroxides which remain in the solution in various forms including but not limited to hydrogen peroxide.
The addition of sodium chloride (table salt) leads to the following additional reactions:
CATHODE
Na+ + e- Na [8]
2Na + 2H2O 2Na+ + 2OH- + H2 [9]
ANODE
2Cl- – 2e- Cl2 [10]
It should further be noted that the Cl2 and OH- reacts as follows:
Cl2 + 2OH- ClO- + Cl- + H2O [11]
Cl2 + OH- HClO + Cl- [12]

Stability
Several parameters can be measured in order to establish the shelf life of HOCL. These include pH, ORP, EC, salinity and FAC (Free available chlorine). The FAC of most generated HOCL’s prove to be unstable and easily evaporates from the water causing an immediate, strong chlorine smell and complicating storage, transport and usage. Produced HOCL is stable and ready to use for months.
Microbial Efficacy
Log 6 reduction Effective against Methicillin-resistant Staphylococcus aureaus (MRSA), Vancomycin-resistant Enterococci (VRE), Human Immunodeficiency Virus Type 1 (HIV-1), Swine Influenza Virus (H1V1), Salmonella enterica and more Micro-organism cannot develop resistance against HOCL, unlike traditional chemical agents.
Mechanism of Action
The mechanism of action in which HOCL eradicates these various micro-organisms is well documented by third party resources. The mode of action is as follows:
The free ions in HOCL rapidly react and denature proteins. HOCL should not be used on protein based products, since it will react and destroy the proteins. Once HOCL comes in contact with a microorganism, it attacks the bacterial proteins located in the cell membranes.
The superiority of HOCL is in that it will eradicate similar antibiotic resistant strains including MRSA and VRE. Secondly, because of the osmolality difference (the conc. Of ion in the solution versus in the cytoplasm), HOCL will induce a rupture on the cell membrane leading to cell lysis.
Toxicity
No evidence of toxicity in any form has been observed in any independent laboratory testing. Based on all this information, it can reasonably be concluded that HOCL is non-toxic and safe to use in both healthcare and commercial spaces.
Summary
Generated HOCL is pH neutral, super-oxidized water generated by electrolysis of a dilute salt solution passing through an electrolytic cell. This process creates large volumes of a gentle but extremely potent antimicrobial solution capable of rapid reduction of bacteria, viruses, spores, cysts, scale and biofilm. HOCL is stable, cost-effective to produce, greener than traditional chemical technologies and can be used in multiple applications across a wide variety of industries.
HOCL is an oxidizing agent due to a mixture of free radicals, giving it an antimicrobial effect. Studies have shown that HOCL is highly biocidal and can substantially reduce pathogens such as Salmonella and E. coli without the use of costly toxic chemicals. In addition, it offers the added benefits of being able to remove biofilm and scale from manufacturing equipment, thus, greatly minimizing a major contributor to contamination problems.
Because HOCL effectively destroys microorganisms, they cannot build up resistance to HOCL as they can to other sanitizers and disinfectants. Standard toxic chemicals can create strains of pathogens that become resistant over time because the cell can expel or neutralize the chemical before it can kill it, thereby causing the overall efficacy of chemical cleaners and disinfectants to be significantly reduced.
Effect of pH on the ratio of free available chlorine.
HOCL has a higher biocidal activity than NaOCL and the disinfecting effect is 80 to 300 times higher than the activity of NaOCL with the same free available chlorine concentration. This greater effect is due to the continual production of free available chlorine through electrolysis without hyperchloration. The free available chlorine is maintained in OCL- ion and is gradually converted into the active form HOCL by the electrical energy.
The rate of dissociation of HOCl is so rapid that equilibrium between HOCl and the OCl- ion is maintained even though the HOCl is being continuously used. For example, if water containing one ppm of titratable free available chlorine residual was introduced into it a reducing agent that consumes 50 percent of the hypochlorous acid, the remaining residual will redistribute itself between HOCl and OCl- ion.
A common myth is that when HOCl is used to disinfect water only OCl– remains. In reality, when HOCl is used, OCl– immediately converts back to HOCl to maintain the percentage division mandated by the pH.
