A few years ago, the key was found to produce HYPOCHLOROUS ACID IN SITU. One of the biocides that in recent years is being used more and more, because of its high oxidizing power, combined with its low application cost and its simple production in situ.
Water is an essential compound for life, to the point that life would not be possible without it, and it is also essential that it be chemically drinkable and microbiologically drinkable.
Advantages of using Hypochlorous Acid
Methods for obtaining Hypochlorous Acid
Hypochlorous Acid can be obtained through three different methods:
1. Chlorine gas hydrolysis
2. Hypochlorite acidification
3. Salt solution electrolysis
Hypochlorous Acid, a new era in drinking water disinfection
Hypochlorous Acid is also produced naturally by macrophages and neutrophils to fight infections, in what is known as a “respiratory burst” during the fight against pathogens (Weiss, 1989).
Its microbicidal spectrum is broad and effective, eliminating them quickly depending on the oxidation-reduction potential (ORP) value (ideally at least 650 mV).
To realize its activity, it should be noted that hypochlorous acid is 90 times more efficient at eliminating microbial pathogens than sodium hypochlorite (bleach) and 10 times more efficient than chlorine dioxide. The doses of use are also totally harmless to humans, animals and the environment.
In practical terms with current knowledge, the value of the oxidation-reduction potential for chlorinated biocides can be interpreted for action on bacteria from:
At 650 mV, viral inactivation is also instantaneous.
GRAM NEGATIVE BACTERIA
GRAM POSITIVE BACTERIA
VIRUS
Hypochlorous Acid has anti-inflammatory and tissue proliferation effects. It inhibits histamine, interleukin 2 and leukotriene 4.
The advantages of HYPOCHLOROUS ACID can be specified in:
The product does not have any negative effect on health and environment. It is classified as NON HAZARDOUS according to the European Union Regulation and authorized with biocide for the sanitization of drinking water (TP5).
In summary
The use of hypochlorous acid (HClO) to disinfect drinking water has several significant advantages:
Problematic
There are currently several biocides used for the disinfection of drinking water that DO NOT COMPLY with the STANDARD of maintaining a stable ORP (Oxidation Reduction Potential) throughout the water supply line. In spite of partially achieving it, they do not reach the minimum value of 650 mV in all of it, leaving space for the microbial presence by not eliminating it totally or doing it slowly.
