Chlorine dioxide as Disinfectant

1. Chlorine dioxide has excellent bactericidal, virucidal, sporicidal, and algicidal properties and because of this, it is used to disinfect water and to inhibit the growth of algae.

Chlorine dioxide is a far more powerful disinfectant than chlorine. A comparison of the biocidal action of chlorine dioxide and chlorine on Cryptosporidium Parvum, E. Coli, and Giardia Lambila is presented in the table below

As we can see from the table chlorine dioxide is a far better disinfectant than chlorine. One of the main advantage of chlorine dioxide is that its Biocidal efficiency is not dependent on pH where as the Biocidal efficiency of chlorine is highly dependent on pH. Chlorine becomes ineffective if the pH value is above 8.

2. Chlorine dioxide is stable in water and a residual level of chlorine dioxide can be maintained to prevent recontamination. Any sample of water with O.2-PPM residual chlorine dioxide is free from contamination.

3. One more advantage of using chlorine dioxide is that it prevents the formation of bio-films in the piping system and hence keeps the piping system clean.

4. Chlorine dioxide does not react with organic matter in water to form Trihalomethanes and Chloramines like chlorine. These substances are toxic and many of them are carcinogenic. Chlorine dioxide does not leave behind any undesirable substances in the water and also due to the above reason the treated water will not have the typical chlorine smell. Due to this reason, in many cases the use of activated carbon filter can be avoided which are used to eliminate traces of chlorine.

Chlorine-di-oxide as an Oxidant

As an oxidant, chlorine dioxide is used for
