Chlorine dioxide
Chlorine dioxide is a powerful antimicrobial compound with a long history of use—best known for its ability to disinfect drinking water (for the past 60 years it has been the main chemical used in municipal water supplies).
The reason is that the chlorine dioxide molecule works, & works well. There are very few pathogenic microorganisms in water anywhere in the world that cannot be made safe for drinking through the use of this powerful little molecule.
It is not the same as chlorine.
There is considerable confusion about whether this product is the same as ordinary chlorine. Apart from sharing one chlorine atom, that is where the similarities end! Both chemicals are powerful oxidizing agents, but the way each does this is entirely different!
Chlorine does NOT discriminate in how it kills, while chlorine dioxide has the unique ability to give and share electrons, meaning it is more specialized in its target. One unique ability of the chlorine dioxide molecule is to actively break down biological membranes—particularly useful in the food industry.
At room temperature it is a yellowish, water-soluble gas with an odor similar to that of chlorine. Once dissolved in water, this gas releases free oxygen—in the same way that hydrogen peroxide does.
The remarkable thing is that when oxygen and chlorine are linked in one molecule, there are VERY few pathogenic microorganisms in water that can survive contact with this compound!
That is why this compound has become the chemical of choice for water sanitation around the world!
