The ideal solution for eliminating pathogenic microorganisms present in water.
Il quarto capitolo dedicato alla monoclorammina riguarda la stabilità delle molecole disinfettanti nell’acqua. Con gli articoli precedenti abbiamo voluto descrivere i benefici nell’utilizzo della monoclorammina come biocida. Ve li siete persi? Abbiamo parlato della capacità della monoclorammina di penetrare il biofilm senza incorrere in pericoli di corrosione e poi abbiamo spiegato come la monoclorammina non produce sottoprodotti tossici dovuti alla disinfezione.
Il quarto capitolo si occuperà di descrivere e chiarire come l’elevata stabilità della monoclorammina rispetto ad altri disinfettanti.
Stability
In chemical terms, the stability of a substance is defined as its ability to maintain its chemical composition. The opposite of stability is the concept of reactivity, where a highly reactive substance is less stable and thus decomposes or transforms quickly and easily.
Let’s now examine how the most commonly used disinfectants for water treatment behave from this perspective:
- Chlorine/hypochlorite
Chlorine is one of the most commonly used disinfectants. It has strong oxidising power, which makes it reactive and therefore unstable. Additionally, it is sensitive to pH: it loses part of its biocidal activity at the typical pH values of drinking water, while maintaining its oxidising power, thus increasing the risk of corrosion. Furthermore, its use can lead to the formation of potentially toxic disinfection by-products.
- Chlorine dioxide
It is a widely used biocide, especially for the prevention of Legionella risk, thanks to its disinfecting power, which is also independent of pH. Chlorine dioxide is characterised by being highly oxidising and very reactive. Its instability causes it to break down and “consume” itself very quickly, depleting its biocidal capacity just as rapidly.
- Monochloramine
Monochloramine is a less reactive and extremely stable molecule, which allows it to persist in water for extended periods, providing prolonged disinfecting action. Furthermore, it remains 100% in its effective form within the typical pH range of drinking water, without leading to the formation of toxic or harmful by-products. This highlights the high stability of monochloramine.
Monochloramine is the best solution.
Monochloramine is a widely known and used disinfectant for drinking water in the United States and Europe. This molecule is suitable for disinfecting both hot and cold water and is permitted in drinking water at concentrations of up to 3 mg/l, according to the World Health Organization.
Monochloramine is a very stable molecule, which allows it to penetrate the deeper layers of the biofilm without “consuming” or decomposing, reaching the bacteria right where they find protection and nourishment. In fact, the high stability of monochloramine in water and its lower reactivity enable it not to exhaust its disinfecting power in the outer organic layers but to reach the deepest part of the biofilm, where it effectively exerts its bactericidal action. This demonstrates the high stability of monochloramine.
The SANIKILL effect
SANIKILL, the system patented by Sanipur for the production and dosing of monochloramine, is the first and only technology that uses this molecule as a disinfectant for the elimination of Legionella and other waterborne pathogens.
Numerous studies published in prestigious international scientific journals have shown that, after just one week of dosing in the water distribution system, the presence of Legionella is reduced below the limits set by regulations.
The SANIKILL technology allows for the controlled and safe in situ production of monochloramine, using specially formulated and optimised precursors developed in our laboratories, which are diluted and therefore completely safe at every stage, from handling to storage. On-demand production ensures that fresh product is always available: the absence of storage systems minimises the presence of disinfection by-products. This guarantees the maintenance of perfect hygienic conditions in the water, the absence of unpleasant odours or tastes, and reduced reagent consumption, making SANIKILL an environmentally friendly technology.
To confirm what has been demonstrated by field applications in hundreds of Italian and American hospitals, studies conducted by Independent Bodies have shown the stability and persistence of monochloramine in water. In contrast, chlorine and chlorine dioxide, due to their more reactive nature, lose their biocidal properties much more quickly.
Massima efficacia biocida, penetrazione del biofilm, elevata stabilità, assenza di sottoprodotti della disinfezione, rispetto dell’ambiente sono solo alcuni dei vantaggi offerti dalla nostra tecnologia. Noi lo chiamiamo: “EFFETTO SANIKILL”.
