Use of Hypochlorite as a Disinfectant

Adding NaOCl to water, HOCl is formed according to the reaction:

The HOCl then separates into nascent oxygen (O*) and hydrochloric acid (HCl).

The O* in the atomic state is an extremely strong oxidant.

NaOCl in effective toward bacteria, viruses and fungi; it is able to disinfect with the same mechanism with which chlorine acts.

Alcavis 100 is produced by electrolytic path in optimized cells with a solution of 180 g/l of NaCl. The product has a concentration of active chlorine of about 12 g/l and a pH value of about 10. The advantage of the Alcavis product for medical use is that of being very stable, inasmuch as it is produced by a process of electrolysis of a chemically pure salt solution, with DSA electrodes, with use of correctly designed cells functioning with optimal currents so as to minimize the concentration of chlorates and maximize the stability of the NaOCl solution. In contrast to other products, it preserves its activity for much longer periods. Since NaOCl is used both to oxidize polluting organic agents and to eliminate pathogenic microorganisms, the necessary concentration of NaOCl depends on the concentration of the pollutants. It is especially necessary to know the concentration of organic pollutants in order to determine the correct concentration of hypochlorite. To decrease the use of hypochlorite in treatment of large quantities of water (sewage or purification), it is always suitable to the procedure of preliminary filtration.

Chlorine-based disinfectants act by forming HOCl. The main characteristic is the structure of the molecule, very similar to that of water (HOH ~ HOCl); therefore, HOCl can easily cross the membrane of the pathogenic cell.

Its intracellular target is represented by the energetic metabolism enzymes of the microbe. The result is that the action of chlorine and hypochlorite on bacteria is very strong and lethal and does not offer the possibility of microbic resistance.
