Water Sanitising
Evaluation of electrically superoxidised water against tropical pathogens
Sponsored research was undertaken in Peru in 1998 to investigate the action of HOCl as a water purification agent against tropical pathogens.
“We found that (HOCl) is active against Vibrio cholerae (Cholera) and Salmonella paratyphi (Typhoid fever).
Drinking water collected from impure sources in shanty towns was found to be contaminated with pathogenic coliform bacteria in 53% of cases but the addition of HOCl to a concentration of less than 0.5ppm AFC killed all pathogenic bacteria.
0.5 ppm AFC is well below WHO maximum chlorine levels for drinking water and is undetectable by taste or smell."

"Dissolution in water produces a series of complex equilibria among a variety of chlorinated and non-chlorinated isocyanurates and free available chlorine (FAC) in the form of hypochlorous acid (HOCl). The latter is widely used for treating potable water, wastewater, water in swimming pools and spas, and many industrial water systems. Elemental chlorine, sodium hypochlorite solution, and calcium hypochlorite are other commonly used sources of FAC. Regardless of the source of FAC, HOCl is the active antimicrobial agent, effective against a wide range of bacteria, fungi, algae, viruses and other microorganisms."
"NaDCC is the sodium salt of a chlorinated hydroxytriazine and is used as a source of free available chlorine (FAC), in the form of hypochlorous acid (HOCl), for the disinfection of water. It is widely used as a stable source of chlorine for the disinfection of swimming pools and in the food industry, since it is more stable in sunlight than most other sources of chlorine. It is also used as a means of disinfecting drinking-water, primarily in emergencies, when it provides an easy-to-use source of free chlorine, and, more recently, as the form of chlorine for household point-of-use water treatment."
"Based on this evidence disinfectants where HOCl is the dominant chlorine species (HOCl and ECAS) would be appropriate alternative chlorine-based disinfectants for POU drinking water applications."
Evaluation of Electrically Superoxidised Water Against Tropical Pathogens
"In this study, a 2% solution of superoxidised water disinfected concentrated V. cholerae, S. paratypi and cholera phage in the laboratory. In a field trial, 2% superoxidised water also killed coliform bacteria in drinking water samples collected from a shanty town."
