Why Chlorine Dioxide is Better than Bleach
Chlorine Dioxide has a higher oxidation capacity, and a lower oxidation strength than most species of chlorine, making it at least 2.6 times more powerful per ppm according to World Health Organization CT values. The pH of the water dilutes bleach's power to solve problems. And, chlorine dioxide does not bond with organic matter to form hazardous by-products in the process. Basically, chlorine dioxide is environmentally safer than bleach, which is commonly used by so many.
Some have asked about the corrosive nature of chlorine dioxide. As an "oxidizer" it is obvious that chlorine dioxide is corrosive, but take note that chlorine dioxide is less corrosive than bleach.
If the water has a high pH, above 8 on the scale (noting normal water is roughly a 7), bleach becomes less effective as the pH goes up. Good news! Chlorine dioxide is effective when used in a water mix as high as a 12 on the pH scale.
Chlorine dioxide breaks down the biofilm that chlorine bleach does not. While many do not know what the biofilm is, this is the ordinary micro-thin coating on all surfaces. At its worse, it can be a film, a crust, or a layer of accumlated micro-debris that contains bacteria, pollution, and so much more.
Biofilms are actually built over time by bacteria using polysaccharides to form a latticework of colonizing film. This film hardens and is mostly resistant to typical clenaing efforts. Chlorine dioxode and ozone treatments penetrating polysaccharide layers to destroy pseudomonas (really bad bacteria) and other base bacteria within the biofilm.
Chlorine dioixde is quite impressive for germ-killing power compared to bleach. Bleach must "Stay Wet on the Surface" (known as Dwell time) for 10-60 minutes to kill many types of bacteria or virus. Chlorine dioxide kills a wide array of bacteria and virus in seconds, or a few minutes. Chlorine dioxide also kills protozoa, cysts; including Cryptosporidium, Giardia and amoeba.
Chlorine dioxide should be used intelligently and there are some basic protocols to follow. Also, there are the "Best Practices for Chlorine Dioxide Treatments" put forth by ERSAI.org. However, if anyone knows how to apply bleach; using chlorine dioxide should be an easy transition.
